About Foams and Foam Materials

Foams and foam materials are made from low density elastomers, plastics, and other materials with various porosities. They are used in a variety of architectural, industrial, medical, and consumer applications. There are six basic types of foams and foam materials: open cellular, closed cellular, flexible, rigid, reticular and syntactic. Open cellular foams have interconnected pores or cells and are suitable for filtration applications. Closed cellular foams do not have interconnected pores or cells, but are useful for buoyancy or flotation applications. Flexible foams can bend, flex or absorb impacts without cracking or delaminating. Reticular foams have a very open structure with a matrix consisting of an interconnecting network of thin material strands. Rigid foams feature a matrix with very little or no flexibility. Syntactic foams consist of rigid microspheres or glass micro-balloons held together by a plastic or resin matrix. 

Foams and foam materials are available in a variety of forms. Some products contain metal, metal alloy or ceramic materials. Others contain plastics, polymers, elastomers, thermoset plastics, thermoset resins, or thermoplastics. Casting resins are plastic or elastomer compounds used to cast parts or molds, or form structures in place. They usually consist of two part (A + B) systems where A is the resin and B is the catalyst or hardener. Casting resins are available as spray foams, froth packs and pourable materials. Molding grade resins are also available, but in the form of pellets. These plastic and elastomer products are suitable for fabricating parts by injection molding, compression molding, blow molding or film extrusion, reaction injection molding (RIM), and resin transfer molding (RTM). Stock shapes for foams and foam materials include bars, boards, blocks, buns, film, rods and sheets.
