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

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
