2. Expanded polyethylene - Wikipedia

   en.wikipedia.org/wiki/Expanded_polyethylene

   EPE foams are low density, semi-rigid, closed cell foam that are generally somewhere in stiffness/compliance between Expanded polystyrene and Polyurethane. Production of EPE foams is similar to that of expanded polystyrene, but starting with PE beads. [1] Typical densities are 29 to 120 kg/m 3 (49 to 202 lb/cu yd) with the lower figure being ...

3. Ethylene-vinyl acetate - Wikipedia

   en.wikipedia.org/wiki/Ethylene-vinyl_acetate

   In recent years, EVA foam has seen popular use in cosplay communities, largely in part due to its ease to work with, durability, and comfort in comparison to traditional plastic-based costumes. [ 7 ] Flower-making foam is a thin sheet made of EVA, which is flexible, and is used by artists and craft makers to make artificial flowers.

4. Polymeric foam - Wikipedia

   [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 ...

5. Sandwich-structured composite - Wikipedia

   en.wikipedia.org/wiki/Sandwich-structured_composite

   The core material is normally of low strength, but its greater thickness provides the sandwich composite with high bending stiffness with overall low density. 2)Open- and closed-cell-structured foams like Polyethersulfone , polyvinylchloride , polyurethane , polyethylene or polystyrene foams, balsa wood , syntactic foams , and honeycombs are ...

7. Polyethylene - Wikipedia

   en.wikipedia.org/wiki/Polyethylene

   [8] [9] Many kinds of polyethylene are known, with most having the chemical formula (C 2 H 4) n. PE is usually a mixture of similar polymers of ethylene, with various values of n. It can be low-density or high-density and many variations thereof. Its properties can be modified further by crosslinking or copolymerization.
