Poly-Foam Shanghai 2015

This conference hosted by Foam Update had 22 quality presentations with over

100 attendees from all over the world at the Hilton Shanghai hotel; Dec. 2-3,

2015. Its front page with enhibition and support is attached in Fig. 1. Counting

years of participation in polymeric foam, it is literally over thousand years of

experience directly and indirectly, chemically and mechanically, regionally and

worldly. Fig. 2 is part of the auditorium during one of the technical sessions. It

is exciting to see so many experts complimenting and challenging one another

in one room for two days. Intermission seemed not long enough for ambitious

young participants in chasing new ideas and developmental paths.The bottom

line is new foam technology, application, and innovation are quite intriguing

and challenging, and its future simply way beyond our comprehension. The

good news is networking and wechat offer a good platform for continued

communication.

The keynote speech delivered by Mr. Mark Donzella; Vice Presdient of

performance packaging of Sealed Air Corp. left a clear impression regarding

the role of marketing in this ever changing and competitive new business

development environment. How to define, develop, and deliver the value to the

targeted customers is so critical to make them successful, then monetize the

value to close the development cycle. Thermoplastic polyurethane (TPU) foam

also captured technical and business attention, due mainly to its performance

merits and economics. As global polyethylene terephthalate (PET) has surplus

in 2015, its performance/cost can make it a good application case. A separate

session was dedicated to PET foam and its cellular formation which simply

highlight its R&D stand for new applications.

Professors Park (U. Toronto) and Cassagnau(U. Lyon1) talked about molded

bead PP foam technology and PMMA nanofoaming, respectively. When we

strive forward into new foaming technology, development trend would always

remind us be realistic in keeping right paces. In PMMA nanofoaming, the

thermoconductivity was reported around 25 mW/oK-min., which seemed lower

than anticipated. We know it is an ongoing research, but, no doubt, it is a good

reality check. Looking at future, 3D printing and elastic networks as shown in

Fig. 3 are intriguing methodology in making cellular structure products yet

without using blowing agent. It is not wise to be locked in a box. We need to be

careful on the frontier technology development to make every benefit for the

business. This conference offers wonderful and useful components, which

should be used properly with other elements to offer a valuable solution to

customers. With this, we are reasonably optimistic to expect more success

stories in the future PFC.

Abstract:

The U.S House on Monday swiftly passed a bill to ban

plastic microbeads in over-the-counter (OTC) and

personal-care products, starting in 2017. The

legislation, which is headed next to the Senate for

review, would ban the manufacture of microbeads

beginning in 2017 and eliminate their use in cosmetics

and over-the-counter drugs in 2018 and 2019,

respectively. The bill cleared the House unanimously

after previously passing the House Energy and Commerce Committee, also without

objection, in November. Plastic microbeads caused concerns among clean water

advocates on the challenging removal process typically done in wastewater treatment

processes. The microbeads are able to crossover into the waterways during these,

inflicting harm to marine life. Currently, there are other natural alternatives available to

replace plastic microbeads in personal care and OTC products.

Publication Date November 30, 2015

Abstract:

What differentiates complex fluids from mere fluids? What makes them unique is that

they are neither solid nor liquid. Among such complex fluids are foams. They are used as

a model to understand the mechanisms underlying complex fluids flow. Now, a team of

French physicists has gained new insights into predicting how complex fluids react under

stretching conditions due to the interplay between elasticity, plasticity and flow. These

findings were recently published in EPJ E by Benjamin Dollet and Claire Bocher from

the Rennes Institute of Physics, in Brittany, France. Ultimately, potential applications

include the design of new, optimised acoustic insulators based on liquid forms, or the

mitigation of blast waves caused by explosions.

Abstract:

Original calcium alginate beads with porous structure and high adsorption surface are

proposed. The beads were synthesized using sodium alginate in the presence of sodium

dodecyl sulfate as foaming agent, NaCl as porogen agent and CaCl2 as cross-linker. They

were characterized by Fourier transform infrared spectroscopy, scanning electron

microscopy and Brunauer–Emmett–Teller method. The adsorption capacity of beads was

tested with methylene blue (MB). The data show that the adsorption efficiency increases

with the amount of beads, decreases with pollutant concentration, and is maximal at pH =

9. The adsorption is fast in the first 3 hours, and slows down thereafter. The kinetic

results show that the adsorption of MB on alginate porous beads obeys the Langmuir

model. A scheme of MB adsorption taking into account the ionic interactions with

calcium alginate beads has been proposed.

Abstract:

The footwear market is addressing eco-sustainable solutions to the continuous demand

for materials that at the same time show lighter weight with higher comfort. Toward this

aim, a biodegradable matrix, poly(vinyl alcohol) (PVA), was used to obtain foams

through an eco-sustainable methodology based on high speed mixing, without the use of

chemical blowing agents. Moreover, considering that good thermoregulating performance

in terms of heat transfer and perspiration is required for good quality shoes,

microencapsulated phase change materials (PCMs) were incorporated into PVA foams.

Foam morphologies investigated by SEM reveal that PCMs are finely dispersed through

the PVA matrix. Mechanical properties of foams were analyzed in terms of compression

behavior and shape memory recovery, triggering the dimensional changes by both

temperature and relative humidity. The thermoregulating properties confirm that the

presence of microcapsules affects the heat transfer phenomenon, since part of the heat

provided by the source is involved in the wax phase transition.

NOVEL CORDIERITE FOAMS FROM PRECERAMIC POLYMERS AND

REACTIVE OXIDE FILLERS

Author(s) Fiocco, L., Bernardo, E.

Sources Materials Letters 159, No.1, 2015, p.98-101



Abstract:

Cordierite (Mg2Al4Si5O18) ceramic foams have been successfully prepared by a novel

approach, consisting of the firing at 1350 °C of commercial silicone resins (Silres® MK

and H62C) embedding micro-sized Mg(OH)2 and Al2O3 powders, acting as reactive

fillers. The foaming was due to a preliminary heating stage, at 300 °C, at which

magnesium hydroxide decomposed, releasing water vapor in the viscous mass offered by

silicone resins before their ceramic conversion. Two different strategies were employed

for the mixing of components, depending on the nature of the preceramic polymer used.

For a liquid polymer, the fillers were added starting from polymer solutions; for a solid

polymer, the fillers were incorporated by melting in a conventional extruder. Despite

significant differences in the formulations and in the mixing, the resulting ceramics are

similar, in terms of remarkable phase purity, total porosity (in the order of 64%) and

mechanical properties (compressive strength≈2.3 MPa).

Abstract:

The incorporation of nanoparticles to polymer foams not only reinforces the cell walls

and struts but can also lead to a decrease of cell size and enhanced cell morphology

which in turn, yield foams with superior mechanical properties. For this purpose, several

studies have focused on identifying close-to-ideal nucleating agents as well as

understanding the influence of processing parameters on foam cell morphology.

This research provides a systemic approach to low-density polystyrene foams produced

with graphene (thermally reduced graphite oxide), talc and carbon nanotubes (MWCNTs)

via foam extrusion. Remarkably, the cell morphologies of polystyrene/thermally reduced

graphite oxide foams show enhanced cell homogeneity with a tremendous increase of the

cell densities by more than one order of magnitude compared to neat polystyrene and its

counterparts.

Abstract:

We studied the foaming behavior of

poly(vinyl alcohol) (PVOH) and

microfibrillated cellulose (MFC)

composites in a batch process using

supercritical carbon dioxide (scCO2)

and water as co-blowing agents. In PVOH/MFC composites, water is an economical

plasticizer. It not only suppresses the potential thermal degradation of PVOH but also

extends the processing window. A uniform cell structure and a high cell density were

achieved in the PVOH/MFC foams. The results showed that cell density was increased by

increased water content. Further, the MFC contained both micro- and nano-sized fibers.

These created numerous heterogeneous nucleation sites and caused local pressure

variations. However, cell density decreased when the MFC was overdosed. Due to the

high crystallinity that then developed around the MFC, the gas content was too low, and

the stiffness was too high. The experimental results also showed that the cell morphology

and density could both be controlled by the water and the MFC content. The effects of

the foaming temperature and pressure on the cellular morphology of the PVOH/MFC

composite foams were examined systematically.

Abstract:

The large quantities of the petroleum-based foam materials used have raised concern due

to their negative effects on the environment, predominantly single-use articles in

packaging applications. Thus, considerable efforts have been put forth to develop

environmentally friendly alternatives and, in particular, starch foams. Many techniques

including extrusion, hot-mold baking/compression, microwave heating, freeze-

drying/solvent exchange, and supercritical fluid extrusion can be used to produce starch

foams with different cellular structures and properties. Starch by itself is, however, rather

weak and water sensitive. To improve microstructure, mechanical and thermal properties,

moldability, water resistance, lightness and other properties of starch-based foams, many

approaches, e.g., chemical modification of starches, blending with various biodegradable

polymers, incorporation of natural fibers, and addition of nanofillers, have been

attempted and are intensively reviewed in this article.

Abstract:

Foam Update

January 2016


In this paper, polypropylene glycol Y-1900, unmodified nano-montmorillonite (MMT)

and organically modified nano-montmorillonite (OMMT) serving as cell openers are

introduced into slow-resilience flexible polyurethane foams (FPUFs), aiming at

investigating the effects of them on cell morphology and the relationships between cell

structure, nano-montmorillonite types and resilient performance of slow-resilience

FPUFs. Experimental results indicate that OMMT can sever as an excellent alternative

for conventional cell openers. The ability of nano-montmorillonite to open cells mainly

depends on their surface property. Both MMT and OMMT are exfoliated in foaming

process and play a significant role in cell diameter for nucleating function. The resilient

performance of foams is closely related to open cell content and polyurethane matrix

nature, due to that the friction effect of nano-montmorillonite and the deformation of

open cells will lead to large energy dissipation. The mechanical properties (tensile

strength, elongation at break and compression set) are related to cell structure and nano-

montmorillonite. The addition of nano-montmorillonite especially organically modified

nano-montmorillonite is an effective method to improve resilient performance and

mechanical strength. However, this improvement is at the expense of impairing

toughness of foams.

Publication Date February 5, 2015

Abstract:

BACKGROUND

Cleanup of oil spills is a worldwide task needed to avoid serious environmental pollution.

Recently, polyurethane (PU) sponge has been used as an oil absorbent, however, its

efficacy is limited by its hydrophilic property.

RESULTS

This work describes the modification of PU sponge with ZnO microrods and palmitic

acid (PA). A coating of ZnO microrods made the surface of PU sponge rough, which

improved the hydrophobicity and oil-adsorption capacity of the sponge. Further

immersion in PA solution reduced the surface energy, which enabled the rough surface to

be superhydrophobic (water contact angle (CA) > 150°). The contact angles of water and

oil on the prepared ZnO and PA modified (ZnO-PA sponge) sponge were 168.9° and 0°,

respectively. Adsorption capacities of ZnO-PA sponge varied between 33 and 44 g g−1

for different oil samples, which were higher than those of the non-modified PU sponge

(21–23 g g−1). Adsorption equilibrium for the adsorption process of ZnO-PA sponge was

achieved within tens of seconds. Additionally, the ZnO-PA sponge showed excellent

selectivity for oil over water, and high reusability.

CONCLUSION

These findings indicated that the superhydrophobic PU sponge was a promising oil

adsorbent for large-scale oil-spill collection.

Abstract:

In this article, the mesh fabric and porous filler are combined with polyurethane (PU)

Result shows that, mesh fabric improves the low-frequency coefficients, and also

increases the puncture resistance by 2 times and 1.5 times for 2-mm-diameter and 4.5-

mm-diameter probes penetrations. Absorption peak shifts to the lower frequency with

increase of fillers content and mesh opening, but static puncture resistance against 4.5-

Abstract:

Poly(methyl methacrylate) (PMMA) nanocomposites were prepared by incorporating

talc, carbon black (CB) and thermally reduced graphite oxide (TRGO) respectively. At a

loading content of 5 wt %, the fillers were well dispersed within the PMMA matrix with

the exception of CB. As expected, the inclusion of the respective fillers led to an increase

of the tensile modulus at the expense of tensile strength and elongation at break compared

to neat PMMA.

The addition of TRGO (5 wt %) increased the dynamic complex shear viscosity (η*) and

storage modulus (G/) of PMMA by one order of magnitude compared to talc and CB at

the same concentration. Van Gurp-Palmen-plot further revealed the formation of filler

network only for CB and TRGO particles.

Physisorption measurements showed that TRGO and CB fillers were more CO2-phillic in

comparison to talc and may have contributed to increasing the amount of CO2 retention

as confirmed by sorption measurements. These features were exploited to prepare closed-

cell microcellular low-density PMMA nanocomposite foams via batch-foam process.

Abstract:

In this study, foaming behaviors of polyetherimide (PEI)/polypropylene-graft-maleic

anhydride (PPMA) blends with different fractions of PPMA are investigated by the

microcellular injection molding (Mucell) using N2 as the blowing gas. The results

indicate that the addition of PPMA can obtain more the interface in blends than PP.

Meanwhile, the microcellular PEI/PPMA foams achieve higher void fraction and cell

density than that of PEI/PP and neat PEI matrix, and then the cell diameter also

significantly decreases from 30 µm to less 10 µm. The excellent cell properties can be

attributed to interfacial effect of binary blends. The binary interface decreases the

nucleation energy barrier and forms sufficient paths which improve diffusibility of

blowing gas, so the microcellular PEI/PPMA foams obtain more nucleating points and

paths of supporting cell growth.

ON THE CELL MORPHOLOGY OF POLY(LACTIC ACID)/

POLYCARBONATE BLENDS USING SUPERCRITICAL CARBON DIOXIDE

Author(s) Bao, D., Liao, X., He, G., Huang, E., Yang, Q., Li, G.



Publication Date June 6, 2014

Abstract:

Poly(lactic acid)/polycarbonate blends were prepared by melt mixing. The

transesterification reaction between poly(lactic acid) and polycarbonate was promoted by

using tetrabutyl titanate as a catalyst. For poly(lactic acid)/polycarbonate (weight ratio of

75/25) blend with catalyst content up to 0.5 wt%, polycarbonate particles finely dispersed

in the poly(lactic acid) matrix and the adhesion between the phases were improved, due

to the enhanced compatibility by transesterification reaction. The blends were foamed by

using batch-foaming process with CO2 as the blowing agent. Cell density of poly(lactic

acid)/polycarbonate blend increased at low-catalyst content, while decreased at high-

catalyst content, which was due to the changes of interfacial properties of blend phases

through transesterification reaction and crystallinity of polycarbonate component. Cell

types of poly(lactic acid)/polycarbonate blends were transferred from submicro-sized and

even nanoscale cells to microscale cells by the deceased crystallinity of poly(lactic acid)

component, which was caused by the increased degree of transesterification reaction and

temperature. The declined viscosity of poly(lactic acid)/polycarbonate blend because of

degradation during blend processing led to large cell size and low-cell density. However,

the improvement of elasticity and viscosity of poly(lactic acid)/polycarbonate blend by
