Our flame-retardant neoprene sponge is a premium closed-cell, general-purpose material that offers excellent weathering and physical resistance along with fire, oil, and chemical resistance. This makes it an ideal choice for applications where fire risk is present.

Key Features

  • Excellent resistance to weathering, fire, oil, and chemicals
  • Available in densities from 130 to 170 kg/m³
  • Thicknesses range from 1mm to 40mm
  • Customisable formats: sheets, strip cut lengths, and bespoke gaskets
  • Option for adhesive backing or lamination

As a closed-cell material, our flame-retardant neoprene sponge forms an air and watertight seal with minimal pressure, providing superior thermal and acoustic insulation compared to open-cell materials. However, it’s important to avoid over-compression, as it can break the cellular structure and significantly reduce sealing capabilities. Always compare the compression data of the material with the pressure rating of your application to ensure optimal performance.

Benefits

  • Creates air and watertight seals
  • Superior thermal and acoustic insulation
  • Versatile and suitable for various applications
  • Customisable to meet specific requirements
