Foam bead supplier and molder JSP Corp. presenting at IPF show

November 07/2011

(Plastics Today) -- Foams made from polystyrene, polypropylene, polycarbonate, and even biodegradable polylactic acid (PLA) will play a key role in vehicle lightweighting moving forward according to foam bead supplier and molder JSP Corp. (Tokyo, Japan). The company sees potential for another 10 kg of foam use in addition to the 5-6 kg that is estimates is currently used.

On show at the IPF show in Japan was a concept foam sandwich door, with partially bio-derived unsaturated polyester (UP) resin covering both sides of an expanded PLA foam. While the UP resin is currently glass fiber, theoretically natural fiber could also be used as a reinforcing material according to Hidehiro Sasaki, General Manager of the Development Department at JSP. The door weighs in at 9 kg, including around 1 kg of PLA foam.

Prototype door module comprises unsaturated polyester sandwiching polylactic acid (PLA) foam. Polycarbonate foam (orange tag) may join expanded polypropylene (blue tags) in auto applications.
Rear seat bases represent a substantial potential market for foamed plastics.

Expanded polystyrene finds use as a protective packaging material for automotive components. Fellow IPF exhibitor Sekisui Chemical (Osaka, Japan) pegs foam usage at 10 kg per vehicle for the OEMs that it serves. The company's strategic product is a blend of PS foam and polyethylene foam, Piocelan, that exhibits superior compression strength as compared to EPP foam and can be molded on conventional EPS machines.
