🔹 What is the temperature range of the closed-cell rubber foam insulation?
The material is designed to operate efficiently within a temperature range of -50°C to 110°C, tested in compliance with GB/T 17794-1999 standards.
🔹 How does this material perform in terms of fire safety?
It features excellent fire performance, holding a Class 0 & Class 1 Fire Rating under BS 476 Part 6 & 7, and meets the 25/50 Flame Spread and Smoke Developed Index standards (ASTM E 84).
🔹 Where is this closed-cell rubber foam insulation typically applied?
It is widely used for insulating shells of large tanks and pipes in construction, commercial, and industrial facilities, central air-conditioning ducts, household air-conditioning joints, and automotive air-conditioning.
🔹 What is the thermal conductivity of this insulation material?
According to ASTM C 518 testing, the thermal conductivity values are ≤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.
🔹 Does the foam insulation provide protection against environmental factors?
Yes, it demonstrates good resistance to U.V. and weather (ASTM G23), ozone (GB/T 7762-1987), and fungi growth (ASTM 21), ensuring long-term durability in varied environments.
🔹 How does this product prevent condensation and save energy?
Thanks to its high water vapor resistance factor (μ ≥ 10000) and low permeability, it blocks moisture ingress, which effectively prevents condensation, frost formation, and thermal loss.
