Organic open cellular foam

By focusing on customer-driven development, American Aerogel has successfully commercialized a form of aerogel materials. Aerocore, a black organic monohthic open cellular rigid foam, can be produced with a wide range of properties and sizes. It can be used as a thermal insulator, acoustic attenuator, chemical support media, electrical conductor, and mechanical shock absorber. 

Cellular rubber is a generic term and includes latex foam produced chiefly by aeration of compounded latex, which is of necessity open-cell because water must be removed rapidly during processing (1). ASTM D 1055 defines flexible cellular rubber as "a cellular organic polymeric material that will not rupture within 60 seconds when a specimen 200 by 25 by 25 mm is bent around a 25-mm diameter mandrel at a uniform rate to produce 1 lap in 5 seconds in the form of a helix at a temperature between 18 and 29 C." The structure of latex foam rubbers consists of a network of open or interconnecting cells. Latex foam rubbers are made from rubber lattices or liquid rubbers. They are manufactured in sheet, strip, molded, or specific shapes (3). 

The UF foam plastics are open-cell cellular materials with the capability of absorbing oils and solvents. UF foam is non-toxic, nonflammable, and stable with respect to almost all organic solvents, light and... 

Javni et al. (2011) studied the possibility of replacing polyol copolymers used in the preparation of flexible PU foams by the incorporation of unmodified and modified montmorillonites. While the addition of the unmodified MMT increased hardness, compression strength, and resilience of the foams, the incorporation of the organically modified MMT resulted in foams with lower modulus, hardness, and compression strength values, a direct result of the higher open-cell contents and poorer cellular structure of the resulting foams, apparently leading to the conclusion that in this specific case the addition of modified MMT led to a counterproductive result.
