pvc nitrile foam and sponge rubber

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.

  • Excellent resistance to acid, fuel and oil
  • Density: 60 – 90 Kg/m³
  • Soft with low compression force to create a seal
  • Low compression set
  • Ozone resistant
  • Chemically inert
  • Temperature range from +85°C to – 50°C (+110°C in Tube format)
  • Fire Retardant to BS476 pt. 6 & 7 Class O

Typical Uses:

  • Oil Seals
  • Cushioning
  • Vibration Dampening
  • Shock Absorption
  • Pipe Lagging
  • Thermal Insulation
  • Construction Applications
  • Medical Applications
