Rubber foam insulation sheet is a black flexible elastomer nitrile butadiene rubber foam. It is an original closed cell elastic foam with a slightly wrinkled surface that makes it adaptable to various shapes of installation, while the expanded closed cell structure makes it an excellent insulating material, which is also effective for reducing HVAC noise.

The rubber foam insulation sheet operates efficiently across a wide temperature range, specifically from -50°C to 110°C, according to the GB/T 17794-1999 test standard.
Yes, it has Class 0 and Class 1 fire ratings under BS 476 Part 6 & Part 7. It also features a flame spread and smoke developed index of 25/50 (ASTM E 84) and an oxygen index of ≥36, making it self-extinguishing and compliant with strict fire safety demands.
The elastomer nitrile butadiene rubber foam is constructed with an expanded closed cell structure. This provides low density (45-65Kg/m³), low thermal conductivity, and high water vapor resistance (μ ≥ 10000), making it an excellent barrier against heat transmission and condensation.
Yes. Under technical testing, it exhibits "Good" resistance to fungi growth (ASTM 21), ozone resistance (GB/T 7762-1987), and long-term resistance to UV radiation and weathering (ASTM G23).
Apart from thermal insulation, the flexible, expanded closed cell structure acts as an acoustic dampener, which is highly effective in reducing HVAC system noise and vibration.
The rolls come in thicknesses starting from 1/4" (6mm) up to 2" (50mm). You can select from standard width options of 1m, 1.2m, and 1.5m to fit your custom installation requirements.
