General Plastics LAST-A-FOAM® WSF-1121 Foam
Categories: Other Engineering Material; Composite Core Material; Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced

Material Notes: LASTAFOAM WSF1121 (Impact Energy Absorption): These flame-retardant, durable, self-skinning foams (also referred to as integral-skin foams) are used extensively in aircraft flight decks and cabin applications. The harder, more durable of our flexible polyurethane foams, this tough integral-skin polyurethane foam system can be pigmented and in-mold painted for a lasting finish. WSF1121 products are used by airframe manufacturers for molded and fabricated flight-deck padding and aircraft interior parts. This self-extinguishing, flexible urethane foam can be custom-molded to your exacting specification. PLEASE NOTE: These foams are not offered for sale as liquid kits or sheet stock. They are only available within a finished parts program.

Advantages:

  • Durable
  • Flame-retardant
  • Self-skinning
  • Custom-molding ability
Applications
  • Flight-deck Padding
  • Flight-deck Parts
  • Passenger Cabin Walls and Ceilings
