attack (hydrolysis). Polyethers also have lower viscosity and
specific gravity.
Polyester based urethanes have superior cut, tear,
abrasion, oil and solvent resistance.
MDI based products have lower isocyanate odour than
similar TDI types and have superior hydrolysis resistance
and often have higher resilience.
TDI based products are less sensitive to moisture, have
shorter demould times and are more user friendly than MDI
product.
Polycaprolactones exhibit good cut, tear, load bearing
and abrasion resistance with the added advantage of
better hydrolysis resistance when compared to Polyesters.
Aliphatic Systems have high resistance to weathering,
high chemical resistance and durability in aggressive
environments.
Polyurea Systems are fast reacting amine terminated
systems used typically in spray applications. These systems
have very good water and chemical resistance.
What are Polyurethanes?
Polyurethane Elastomers are unique design and construction
materials combining many of the advantages of rigid plastics,
metals and ceramics with the
extensibility of rubber.
While it is not claimed that polyurethanes are the answer to
all problems, they are extremely versatile and this is the key
to their widespread and growing use.
The main types of polyurethanes are:
POLYETHER/TDI POLYCAPROLACTONE/TDI
POLYETHER/MDI POLYCAPROLACTONE/MDI
POLYESTER/TDI ALIPHATIC SYSTEMS
POLYESTER/MDI POLYUREA SYSTEMS
These are also known as the “chemical backbones”. Each
has its own performance advantages. Please consult the
Era Polymers Technical Service Department for specific
recommendations.
As a general guide:
Polyethers are recommended for applications where
parts undergo dynamic stress, i.e. they incur lower heat
build-up. They also have advantages in high resilience,
low temperature performance and resistance to water

They are polymeric materials containing urethane groups
produced by the reaction of a polyol with an isocyanate.
They are materials offering a
number of unique properties
which enable products to be
manufactured to meet a range of
demanding applications.
They are materials which can
be processed with low energy
consumption and relatively low
capital outlay for machinery
to yield products which show
cost saving through improved
performance.

Properties of Erapol Elastomers
Polyurethanes compete against
many other materials including rubber,
plastic and metals.
The most common method of
classifying polyurethanes is
according to their hardness.
The diagram (right) shows
how polyurethanes compare
in hardness to other materials.

1 . HardnessErapol elastomers are available
in a wide range of hardness, from
10 Shore A, which is softer than
an eraser, to 85 Shore D which is
much harder than a golf ball. For
those unfamiliar with this method
of measuring hardness, the pictures
to the right show two typical
Durometers.
Hardness measurement is a useful
tool, however variation in readings by
one or two units can be encountered
when measuring most polyurethane
and rubbers.
Shore A is the most common
hardness scale used up to 95 Shore A.
Any reading above this hardness level
should be measured in Shore D scale.
The comparison between the two
scales is outlined above in Diagram 1.

DIN Abrasion Testing Machine
Taber Abrasion Testing Machine
2 . Abrasion ResistanceIn severe wear applications Erapol
elastomers offer outstanding
durability when compared with
rubbers, plastics or even metals.
It should be emphasised that
abrasion resistance is a complex
property. Selection of an appropriate
Erapol elastomer should be based
on actual experience or simulated
service tests. For comparative
abrasion data please see Resistance
Charts on pages 34 – 35.

Properties of Erapol Elastomers
3 . Compression PropertiesErapol elastomers exhibit greater
load-bearing capacity than
conventional elastomers of equal
hardness. This leads to successful
applications such as wheels and
industrial tyres, feed rollers and
stripper springs. In addition to high
load bearing properties in both
tension and compression, Erapol
elastomers also have a high load
bearing capacity in shear.
4 . Mechanical PropertiesAt low hardness all elastomeric
materials, including Erapol
elastomers will flex under impact.
As conventional elastomers are
compounded up to higher hardness
they tend to lose elasticity and
crack under impact. On the other
hand, Erapol elastomers when at
their highest hardness levels, have
significantly better impact resistance
than almost all plastics.
The inherent toughness, combined
with the many other outstanding
properties associated with the high
hardness Erapols, leads to many
applications in engineering.
5 . Tear StrengthTypically, tear strength is a strong
indication of toughness and
durability. High tear strength leads to
longer service life. Erapol elastomers
in this regard have a distinct
advantage over other conventional
elastomers.
6 . ResilienceResilience in conventional elastomers
is generally a function of hardness.
This often undesirable relationship
does not hold true with Erapol
elastomers. Products are available in
a wide range of resilience.
In shock-absorbing elastomer
applications, low rebound
compounds are usually used i.e.
resilience range of 10-40%. For high
frequency vibrations or where quick
recovery is required, compounds
of 40-65% resilience are used. In
general, toughness is enhanced by
high resilience.
7 . Low Temperature Properties
Many Erapol elastomers remain
flexible at very low temperatures and
possess outstanding resistance to
thermal shock. The low temperature
resistance of Erapol elastomers has
led to applications below -50°C.
1. Compression Set (ASTM D-395 Method B)
Measures the amount of
permanent deformation a part will
undergo when loaded for a period
of time. In ASTM D-395 Method B
(see above) a load is generated by
imposing a 25% compression on
the sample.
2. Compression Deflection
(ASTM D-575)
This is defined as a compression
test in which the force required
to cause a specified deflection
is determined. Commonly used
strain values for this test are 5%,
10% and 25%.
There are two common test types used to measure tear strength:
Measures resistance to tear initiation.
Measures tear propagation.

Properties of Erapol Elastomers
8 . Tensile PropertiesErapol elastomers are characterised
by high elongation, high tensile
strength and high modulus. This
provides a combination of toughness
and durability, over conventional
elastomers.
Tensile tests are performed on a
tensometer as shown (see right). In
this test we are interested in the shape
of the overall stress strain curve (see
graphs below). The more area there is
under the stress-strain curve the higher
the toughness of the material.
We are also interested in various points
along the curve including the ultimate
tensile strength and elongation of the
Erapol elastomers.
Tensile Strength (ASTM Methods D412 and E6)
The maximum tensile stress a
material is capable of developing.
It is the force per unit of the original
cross-sectional area which is
applied at the time of rupture of a
specimen. It is known variously as
breaking load, breaking stress and
ultimate tensile strength. A dumbell
specimen is used for the test.
Elongation (ASTM Method D412)
The extension between two points produced by a tensile force applied to a
specimen. Measured as a percentage of the original distance between the
marks. A dumbell specimen is used for the test. Ultimate elongation is the
elongation at the moment of rupture.
9 . Flex PropertiesErapol elastomers resist cracking
under repeated flexing. The rate of
cut growth under flexing may be
reduced by decreasing the thickness
of the part. Unlike other conventional
elastomers, Erapol elastomers can be
used in very thin sections because of
their strength and toughness.
10 . Dry Heat ResistanceWhilst many Erapol elastomers
are only suitable for continuous
operation up to 90°C, intermittent
use up to 120°C is possible. Using
specially formulated materials,
continuous operation up to 120°C or
even higher can be achieved.

Properties of Erapol Elastomers
11 . Water ResistanceErapol polyether elastomers are
resistant to the effects of water
immersion and have excellent
long-term stability in water up to
50°C. Continuous use in hot water
over 80°C is not recommended for
standard systems.
Water absorption is very low, in
the range of 0.3-1.0% by weight
and volume swell is negligible.
This means, for example that
Erapol elastomers can operate at
close tolerance in water lubricated
bearings without fear of seizure.
The moisture vapour transmission
rate of Erapol elastomers is relatively
high and advantage is taken of
this fact in some applications, e.g.
poromeric shoe upper materials.
However, where this property might
be disadvantageous, the advice of
our Technical Service Department
should be sought on the suitability of
Erapol elastomers for any particular
application.
13 . Oxygen and Ozone Resistance
Products made from Erapol
elastomers are highly resistant to
degradation by atmospheric oxygen
and ozone. Tests on samples, aged
over 500 hours in an atmosphere
containing 3ppm ozone, show
no attack even while under 20%
strain. Past experience has shown
that materials which resist the
concentration for several hundred
hours are virtually immune to
attack by normal atmospheric
concentrations.
This makes Erapol elastomers highly
successful when employed around
electrical equipment, without the
hardening and cracking often
experienced with conventional
elastomers and indeed many plastics.
14 . Oil, Grease and Chemical Resistance
Many rubbers and plastics have
excellent resistance to one or more
specific solvents, oils or chemicals.
Erapol elastomers are resistant to
a wide range of chemicals which
means they can be used in a
multitude of chemical environments
with the exception of strong acids,
alkalis and certain solvents.
As with all materials being examined
for oil and chemical resistance, it
is best to place a sample of the
material in actual service. If this
is not practical, tests should be
devised which simulate actual service
conditions as closely as possible.
For specific information on chemical
resistance, please see the Chemical
Resistance Chart on
page 36.
12 . Electrical PropertiesTypically Erapol elastomers have very
good insulating properties and are
used in potting and encapsulating
applications.
8
Properties of Erapol Elastomers
15 . Radiation ResistanceErapol elastomers are considered
to have better resistance to gamma
ray radiation than conventional
elastomers. They retain a high
proportion of their original flexibility
and toughness when exposed to
gamma radiation.
16 . Fire ResistanceErapol elastomers can be formulated
to meet several self extinguishing or
fire resistant specifications.
17 . Mould, Mildew, Fungus Resistance
Suitably formulated Erapol
elastomers, usually polyether based,
do not support fungal growth and
are generally resistant to such attack.
This makes them particularly suitable
for tropical environments.
18 . Frictional PropertiesErapol elastomers resemble most
plastics and elastomers, in that
friction against non-lubricated
surfaces generally decrease with
increasing hardness. A high
coefficient of friction is valuable for
such products as solid industrial
tyres, feed rollers, drive rollers etc.
High hardness compounds have the
lowest coefficient of friction, and
formulations having very low values
are available. Such formulations are
widely used for bushings, bearings
and wear strips. Wear of shafts and
mating surfaces is minimal, and
usually considerably less than with
plastic materials.
20 . MachinabilityErapol elastomers can be
machined using conventional
equipment but you should consult
our Technical Service Department for
more information.
21 . Variable Temperature Testing
Sub zero temperature testing
is primarily designed for foam
cryogenic applications where
products are routinely analysed at
temperatures below -165oC. This
equipment also allows Era Polymer’s the capability of testing elastomers
at elevated temperatures to specific
test methods including Tensile,
Elongation, Compression and Angle
tear (Die C). Elevated and sub zero
temperature testing has extended
Era Polymer’s testing capabilities.
19 . Bonding to other materials
During the initial moulding process
and under controlled conditions,
Erapol elastomers can be bonded
to a wide variety of substrates. High
bond strength can be obtained to
most metals, wood and many plastics.
Bond strength often exceeds the tear
strength of the Erapol elastomers.
The bond strength of Erapol to metal
is usually several times higher than
that of rubber to metal.
It is more difficult to bond cured
Erapol elastomer sheet or moulding
to other materials but special
techniques have been developed to
satisfy most requirements.

Erapol Product Data and Processing Guide
1 . Shelf Life and StorageMost Erapol brand prepolymers have
a shelf life of at least 12 months when
stored unopened in their original
containers at temperatures less than
30°C. The isocyanate content of all
Erapol prepolymers will decrease by
reaction with moisture or heat. Partial
drums should be blanketed with dry
nitrogen.
2 . Effects of Heating the Prepolymer
The isocyanate (NCO) content of all
prepolymers decreases with time and
especially with exposure to heat. The
table below shows the accumulated
time taken at various temperatures to
degrade prepolymers.
3 . ToxicityErapol prepolymers contain reactive
isocyanate groups and should be
handled with care. Avoid inhalation
of vapours and skin contact.
Appropriate personal protective
equipment (PPE) should be worn
and adequate ventilation provided.
For further information consult the
Material Safety Data Sheets.
4 . Effects of Curative LevelAll physical properties of Erapol elastomers are sensitive to curative level.
The curative level is often expressed as % theory. The table below shows how
physical properties vary with % theory.

Glossary of Terms
Additive – A material which does not take part in the chemical reaction but is included to alter the final product eg. fillers, pigments, flame retardants etc.
Casting – The filling of moulds with liquid polyurethane.
Catalyst – An ingredient in polyurethane systems which initiates a chemical reaction or increases the rate of chemical reaction.
Chain Reaction – Lengthening of the main chain or backbone of polymer molecules by end to end attachment.
Component – A separately metered stream of liquid which will be directly introduced into the mixing head.
Cross Linking – The formation of chemical links between the molecular chains.
Cure – Refers to the hardening or build-up of properties of a polymer material by cross-linking of polymer chains.
Curing Agent – Material that starts the reaction with the Prepolymer when added.
Cycle Time – A term most commonly used in situations where many items are being manufactured on an automatic or semi–automatic production line. It includes the time required for mould preparation, including release agent application, dispensing of components, reaction, cure and demould.
Degradation – The deterioration of a substance caused by contact with its environment.
Demould Time – The time between dispensing the liquid components into the mould and removing the article being produced.
Dew Point – The temperature at which a vapour begins to condense.
Elastomer – A flexible or semi-rigid rubber-like material not necessarily made from what is conventionally thought of as a rubber.
Elongation – The increase in length of a specimen at the instant before rupture occurs. Expressed as a percent of original length.
Exotherm – Heat generated by a chemical reaction.
Flame Retardant – A substance which is added to a polymer formulation to reduce or retard its tendency to burn.
Hardness – The surface property relating to the resistance of indentation.
Hydroxyl Group – The combined oxygen and hydrogen radical (–OH) which forms the reactive group in polyols.
Impact Resistance – Ability to withstand mechanical force without failure or loss of properties.
Isocyanate – The group of chemical compounds having one or more NCO groups attached to the main chain.
MDI – An abbreviation for diphenylMethane Di Isocyanate.
Microcellular – An elastomer of cellular or foam structure.
Mil – One thousandth of an inch, 0.001 inch. A unit used to measure coating thickness.
Moulding – The process of producing a finished article from a closed mould.
NDI – Naphthalene Di Isocyanate.
NCO – Nitrogen, Carbon, Oxygen. The chemical formula for an isocyanate group.
Polyester – Polymeric compound, with the reactive hydroxyl groups containing ester linkages.
Polyether – Polymeric compounds with reactive hydroxyl group containing ether linkages.
Polymer – A high molecular weight compound, natural or synthetic, whose chemical structure can be represented by a repeated small unit.
Polyol – A chemical compound with more than one reactive hydroxyl group attached to the molecule.
Post Cure – Refers to the period after casting, either in mould or after demoulding, before the material has developed full physical properties by cross linking of polymer chains.
Pot Life – The length of time after mixing together of the two components during which the polymer remains sufficiently liquid to be poured.
Prepolymer – A chemical intermediate manufactured by reacting raw isocyanate with polyol.
PTMEG – Poly Tetra Methylene Ether Glycol
PU – Abbreviation for Polyurethane
RIM – Reaction Injection Moulding. A process of injecting a fast reacting mixture of polyurethane into a mould.
System – A rather ambiguous term used to describe almost any combination of mechanical parts or chemicals which have some relationship to each other. Often used to describe the supply of all chemical components needed to produce a polyurethane.
TDI – An abbreviation for Toluene Di Isocyanate.
Thermoset – A polymer that irreversibly cures from a liquid state to a solid state.
Thermoplastic – A polymer that turns to a liquid when heated and freezes to a solid state when cooled.
Thixotropic – A material that resists slumping or sagging when applied to a vertical surface.
Viscosity – A measure of how easily a liquid flows. The lower the number the thinner the liquid.
Volatile Organic Components (VOC) – Organic materials which evaporate at normal temperatures and pressures, organic materials which have vapour pressure greater than 0.1 mm Hg at one atmosphere.
