NYLONNYCAST ® / NYLOIL® / NYMETA LTM / SUSTA MID® / TECAMID TM

4 NYLON • 1.888.CURBELL • www.curbellplastics.com

Nylon is a strong, stiff engineering plastic with outstanding bearing and wear

properties. Nylon is frequently used to replace metal bearings and bushings,

often eliminating the need for external lubrication. Other benefits include a reduc-

tion in part weight, less operating noise, and decreased wear on mating parts.

Nylon is available in a variety of specialty formulations. Molybdenum disul-

phide-filled and oil-filled nylons have enhanced wear properties, while heat

stabilized nylon will withstand higher operating temperatures. For enhanced

strength and stiffness, nylon is also available in glass-filled grades.

In power transmission applications NYMETALTM billets made with nylon and a

metal core combine the performance advantages of nylon and metal into one

cohesive unit. The billets can be manufactured into many different components

including gears, rollers, sprockets, and augers.

PAI (polyamide-imide)TECATORTM

6 PAI • 1.888.CURBELL • www.curbellplastics.com

PAI (polyamide-imide) is an extremely strong and stiff plastic material. It is often

used in elevated temperature environments where other thermoplastics would

lose their mechanical properties.

PAI is a very dimensionally stable material with an extremely low coefficient

of thermal expansion making it an excellent choice for applications that require

machining to tight tolerances.

PAI is available in a variety of formulations including electrical, bearing and wear,

and glass-filled grades. Electrical grade PAI has extremely high dielectric strength

and it is often used for applications where it functions as an electrical

insulator. Bearing grade PAI can be used for demanding bearing applications that

require extreme loads, speeds, and/or elevated temperatures. Glass-filled PAI has

enhanced strength and stiffness.

ULTEM®

(polyetherimide)

SUSTA ® PEI / TECAPEI TM

2 ULTEM® • 1.888.CURBELL • www.curbellplastics.com

Ultem® is a semi-transparent high strength plastic material that can operate in

high service temperature environments. Ultem® is resistant to hot water and

steam and can withstand repeated cycles in a steam autoclave. Ultem® has

outstanding electrical properties, with one of the highest dielectric strengths of any

thermoplastic material. Ultem® is often used instead of polysulfone when superior

strength, stiffness, or temperature resistance is required.

Ultem® is available in glass-filled grades with enhanced strength and stiffness.

POLYIMIDE SHAPES

POLYIMIDE SHAPES • 1.888.CURBELL • www.curbellplastics.com

DupontTM Vespel® Polyimide is an extremely high temperature, creep resistant

material that is often used in high heat environments where thermoplastic materials

lose their mechanical properties.

Vespel® is available in a variety of formulations including unfilled grades and

several low friction and wear grades. Unfilled Vespel® has outstanding sealing

properties when it interfaces with metal mating parts. These properties make

Vespel® ideal for use in high temperature and high pressure or high vacuum valve

seat and gasket applications.

Bearing grade Vespel® will operate successfully without lubrication in many high

load, high speed, and/or high temperature environments where thermoplastic

bearings and many metal bearing materials may quickly fail.

The new SCP family of DuPontTM Vespel® Polyimide Shapes exhibits enhanced

mechanical properties and superior thermal stability.
