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)
Polyethylene bead foams (including) EPE can be used to replace both polystyrene foam, and both rigid and flexible polyurethane. Uses include cushioning applications, and impact absorption applications including packaging. [4] Consumption of polyethylene for PE foam was estimated at 114x10 6 kg in 2001. The majority was used for non-crosslinked ...

A printer cartridge made of PPE and polystyrene; it is an example of a product which requires good dimensional stability and accuracy to fit.. PPE blends are used for structural parts, electronics, household and automotive items that depend on high heat resistance, dimensional stability and accuracy.
IKEA's Better Shelter uses structural panels made out of polyolefin foam, stating, "They are tough and durable.". [17] Piping systems for the conveyance of water, chemicals or gases are commonly produced in Polypropylene, and to a much greater extent Polyethylene. Piping systems in high-density Polyethylene (HDPE, PE100, PE80) are fast becoming ...
Demand for plastic resins in Europe during 2017 as a percentage of total plastic demand. [1] A comparison of standard plastics, engineering plastics, and high-performance plastics
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

Polymer foam beads [ edit ] Polymer Foam Beads can have a bulk density as low as 0.011 g/cc and range in size from 45 microns to over 8 mm. Common drawbacks to using Polymer Foam Beads in formulated systems include static, temperature, and chemical resistance limitations and difficulty achieving a homogenous blend within a formulated system due ...
