Polyether Foam

Each of our polyether foams has different additives and properties to make it suitable for a specific market.

AB: Used in flame-lamination applications, especially for automotive-trim systems. These foams will pass FMVSS-302.

AF: Similar to AB foams, but with additional flame retardant to help composite materials pass the FMVSS-302 burn test.

AL: Designed for automotive trim systems where pressure-sensitive adhesives (PSA) and other adhesives are used instead of flame lamination to attach the upholstery. These foams will pass FMVSS-302.

ET: These are standard ether foams with no additives. In higher-density ranges, these foams may pass FMVSS-302 but are not designed specifically to do so.

FL: These foams are thermoformable for flame lamination. The higher density grades may pass FMVSS-302 but are not specifically designed to do so.

FS: These foams are the same as the FL grades but with an added biocide. These foams were originally designed for boat seat covers, where anti-microbials are important. However, FS foams are also widely used in shoe insoles.
