Nitroprene is a high quality, technical grade, closed cell foam derived from Nitrile rubber. Applications include thermo-acoustic insulation, pipe insulation and wrestling mats. Its chemical durability and UV resistance makes Nitroprene a strong candidate for superior performance in the aquatic, aerospace, and automotive industries as well as many others requiring materials that need to be non-flammable (25/50 rating), hypoallergenic, chemically resistant, heat sealing, and/or be post formed into various designs. See the technical specification sheet below. Nitroprene insulation is one of the best thermal insulators sold in the U.S. for hot/cold water lines
