caption_attribution_description: English: Solid polymeric foam for packaging under the optical microscope
context_page_description: A polymeric foam is a foam, in liquid or solidified form, formed from polymers.
  Examples include:
  Ethylene-vinyl acetate foam, the copolymers of ethylene and vinyl acetate; also referred to as polyethylene-vinyl acetate
  Low-density polyethylene foam, first grade of polyethylene
  Nitrile rubber foam, the copolymers of acrylonitrile and butadiene
  Polychloroprene foam or Neoprene
  Polyimide foam
  Polypropylene foam, including expanded polypropylene and polypropylene paper
  Polystyrene foam, including expanded polystyrene, extruded polystyrene foam and sometimes polystyrene paper
  Styrofoam, including extruded polystyrene foam and sometimes expanded polystyrene
  Polyurethane foam
  LRPu low-resilience polyurethane
  Memory foam
  Sorbothane
  Polyethylene foam, as used in PEF rod
  Polyvinyl chloride foam
  Closed-cell PVC foamboard
  Silicone foam
  Microcellular foam
