The rubber foam sheet features a low and stable thermal conductivity of 0.034 w/m.k. Under specified test conditions (ASTM C 518), the thermal conductivity is ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C.
These sheets are widely used for sound isolation in wall planking, sound absorption in air ducts, and decorative acoustic treatments in entertainment venues. They are also suitable for shock absorption and pressure relief in delicate instruments and industrial equipment.
Yes, the rubber foam sheet has an excellent fire rating of Class 0 & Class 1 according to BS 476 Part 6 & Part 7 standards. It also achieves a Flame Spread and Smoke Developed Index of 25/50 (ASTM E 84) and an Oxygen Index of ≥36 (GB/T 2406, ISO4589).
It features a low water absorption rate with a value of 20% by volume tested under ASTM C 209, combined with high water vapor permeability resistance (μ ≥ 10000) under DIN 52 615 standards, making it highly effective against moisture ingress.
Yes, the sheet exhibits outstanding durability. It has passed tests showing good resistance to fungi (ASTM 21), ozone (GB/T 7762-1987), and long-term exposure to U.V. radiation and weathering (ASTM G23).
Thicknesses range from 1/4" (6mm) up to 2" (50mm). Depending on the thickness selected, rolls are available in widths of 1m, 1.2m, and 1.5m with lengths adjusting from 4m up to 30m to meet different installation requirements.
