Frequently Asked Questions
What is the temperature range for this closed-cell rubber foam insulation?
The material operates reliably within a temperature range of -50°C to 110°C, conforming to GB/T 17794-1999 test standards.
What is the fire performance rating of the insulation material?
It achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & Part 7, and meets the ASTM E 84 standard with a Flame Spread and Smoke Developed Index of 25/50.
How effective is this material at preventing moisture condensation?
With a highly resilient closed-cell structure, the water vapor permeability is extremely low (≤0.91×10⁻¹³ Kg/(m.s.pa)), which provides superior condensation prevention and frost protection.
Does this insulation withstand outdoor weathering and UV exposure?
Yes, it has been tested under ASTM G23 standards and demonstrates good resistance to U.V. radiation, ozone (GB/T 7762-1987), and fungi (ASTM 21).
What is the thermal conductivity rating at different temperatures?
Tested using 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.
