Polymeric foam

Solid polymeric foam for packaging under the optical microscope.

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#Foams (PS) foam
  • Expanded polystyrene (EPS)
  • Extruded polystyrene foam (XPS), sometimes sold under brand name Styrofoam
  • sometimes polystyrene paper (PSP)
• 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
