PVC Nitrile

As one of the UK’s leading foam converters, Intec Foams specializes in the precision engineering and custom supply of high-performance PVC Nitrile (NBR) sponge rubber. We bridge the gap between raw material manufacturing and bespoke component design, transforming low-density thermal insulation foams into precision-cut gaskets, seals, and specialized industrial components tailored to your exact application.

PVC Nitrile is renowned for its exceptional resilience against oils, fuels, acids, and extreme temperature variations (-50°C to +110°C). Offering superior acoustic absorption, UV resistance, and fire retardancy—including compliance with BS 476 Class O and UL94 V-0 standards—this supersoft, semi-closed cell material provides an ideal barrier for fluid sealing, thermal insulation, and vibration dampening across demanding building, automotive, and medical environments.

Whether your project requires continuous 10-meter rolls, custom-split tube formats, or intricate die-cut shapes, our state-of-the-art conversion facilities deliver exact-spec solutions. From applying custom self-adhesive backings to slitting precision sealing tapes and coils, our technical team works directly with engineers and procurement specialists to ensure optimal material performance, tight tolerances, and reliable UK-wide supply.

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
