Fire Retardant Foam

We stock more fire retardant (FR) foams that meet the FAR 25.853 specification than anyone. We carry FR foam from the following manufactures: Carpenter, Dow Chemical, EAR Confor, Foamex, NCFI (DAX), Zotefoams, Rubatex, and Youngbo just to name a few.

These foams are always in stock and we can provide certification to the FAR 25.853 specification.




ETHAFOAM™ Packaging Products offer foam solutions that are lightweight and buoyant, making them ideal for commercial airline industry applications. These specially formulated foams contain flame-retardant additives designed to meet the Federal Aviation Regulation (FAR) 25.853 (a) for commercial aircraft interior compartment components.

Special flame retarded grades of PLASTAZOTE foams are able to meet the requirements of FAR/CS 25.853(a) App F Pt I. Additionally, ZOTEK F grades, being inherently non flammable, are able to meet the Radiant Heat Panel test FAR 25.856 (a) App F Pt VI and have low smoke density, low toxic gas emission and low heat release. The new ZOTEK F grades designated ZOTEK F HT offer an additional operational temperature limit of 160°C, an improvement of +50°C over the current ZOTEKF range. They also offer enhanced chemical and solvent resistance, combined with higher levels of structural rigidity.

All of these closed cell foams can be converted easily using traditional foam fabrication techniques such as sawing, routing, gluing, laminating, welding and die-cutting. They can also be thermoformed into complex single component structures providing many benefits over multi-layer foam systems, such as weight and cost reduction.

PLASTAZOTE foams are used in many seating and soft trim areas. The low-density closed cell nature of these foams allows significant weight reduction in seat cushions. Additionally, they are used to provide buoyancy or support in crucial areas of seat cushions, improving both comfort and durability.

PLASTAZOTE foams are used to provide soft touch and energy management around seating areas. These include foam-backed fabrics used around superior seating, seat armrests and crash pads on the rear of headrests

ZOTEK F foams show very low heat-release values, (a requirement for cabin interiors) and may be used in conjunction with other materials, such as leathers, that generally exhibit higher OSU values where ‘average’ results for material combinations need to be achieved.
