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.
Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.
Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
Thermosets and thermoset materials are crosslinked polymeric resins that are cured or set using heat or heat and pressure. They generally have a higher resistance to heat than thermoplastics.
