Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in either closed-cell or open-cell form.
Foam rubber was first made in 1929, by E. A. Murphy [2] and Eric Owen, two research chemists at Dunlop Rubber, who used whipped latex. In 1937, isocyanate-based materials were first used to make foam rubber. After World War II, styrene-butadiene rubber replaced many natural types of foam. Foam rubber has been used commercially for a wide range ...
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [1] and textiles.
