When PVC and Nitrile are combined by polymerisation, they product is a soft, closed cell sponge rubber which needs a low deflection force to create a seal.
PVC/Nitrile (NBR) Sponge Rubber ST-O – (BS 476 class O)
Used as a low density thermal insulation foam in Building & Construction. It is available in sheets, rolls or in tubes. The rolls are either skin/skin or skin/cell depending on the thickness required. It can also be converted into strips or gaskets and if required a self adhesive can be applied. We have a range of different inside diameters and wall thicknesses in semi split tube format with skin on the outside.
The foams can be supplied with or without a self adhesive backing in sheet or roll format and can be cut into coils for sealing tapes.
