Polymeric foam

A polymeric foam is a special foam, in liquid or solidified form, formed from polymers.[1]

Examples include:

  • Ethylene-vinyl acetate (EVA) foam, the copolymers of ethylene and vinyl acetate; also referred to as polyethylene-vinyl acetate (PEVA)
  • Low-density polyethylene (LDPE) foam, first grade of polyethylene (PE)
  • Nitrile rubber (NBR) foam, the copolymers of acrylonitrile (ACN) and butadiene
  • Polychloroprene foam or Neoprene
  • Polyimide foam
  • Polypropylene (PP) foam, including expanded polypropylene (EPP) and polypropylene paper (PPP)
  • Polystyrene (PS) foam, including expanded polystyrene (EPS), extruded polystyrene foam (XPS) and sometimes polystyrene paper (PSP)
    • Styrofoam, including extruded polystyrene foam (XPS) and sometimes expanded polystyrene (EPS)
  • Polyurethane (PU) foam
    • LRPu low-resilience polyurethane
    • Memory foam
    • Sorbothane
  • Polyurea foam
  • Polyethylene foam, as used in PEF rod
  • Polyvinyl chloride (PVC) foam
    • Closed-cell PVC foamboard
  • Silicone foam
  • Microcellular foam
