The rubber foam insulation operates efficiently within a temperature range of -50°C to 110°C, tested in compliance with the GB/T 17794-1999 standard.
The insulation material achieves Class 0 and Class 1 fire ratings according to BS 476 Part 6 & 7 standards, indicating superior fire retardant performance.
Tested under ASTM C 518, 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, ensuring excellent thermal efficiency.
The product features highly resistant water vapor permeability (≤0.91×10⁻¹³ Kg/(m.s.pa), with μ ≥10000) and a maximum water absorption of 20% by volume (ASTM C 209), preventing moisture build-up.
Yes, the material exhibits excellent resistance to environmental factors, scoring "Good" for fungi resistance (ASTM 21), ozone resistance (GB/T 7762-1987), and resistance to UV rays and weathering (ASTM G23).
They are widely applied in central air-conditioning pipelines, hot water pipes, industrial low-temperature systems, refrigeration lines, as well as environments with high cleanliness and fire safety demands like electronics, food production plants, chemical factories, and public buildings.
