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.
Sound proofing and acoustic materials are used to attenuate, deaden, or control sound and noise levels from machinery and other sources for environmental amelioration and regulatory compliance.
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.
