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 (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
