Foam, honeycomb and core materials are plastics, ceramics or metals containing closed or open internal cells or pores for composites, tooling, modeling, insulation or floatation.
Foams and foam materials are industrial products made from low density elastomers, plastics, and other materials with various structures and porosities.
Glass fibers and fiberglass cloth consist of bulk, chopped fibers or continuous strands of glass. Glass fibers and fiberglass cloth is used in reinforcing plastics and composites as well as other specialized electrical and thermal applications.
Thermal insulation and fireproofing materials reduce the flow of heat through the thickness of the material. They are typically fiber-based or foam structures prepared from thermally-stable materials.
