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 ...
A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1] Examples include:
Animals do not recognize polystyrene foam as an artificial material, may mistake it for food, and show toxic effects after substantial exposure. Full or partial bans of expanded and polystyrene foam commonly target disposable food packaging. Such bans have been enacted through national legislation globally, and also at sub-national or local ...
Direct injection expanded foam molding (also known as injection molded foam) is a manufacturing process that creates soft foam products direct from a compound into a final product. [1] This process eliminates the steps normally required for die-cutting and compression molding , because it manufactures the foam and the product, simultaneously.

This is a list of insulation materials used around the world.. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber , natural latex , or polyurethane .
