What are the primary materials used in this rubber foam insulation?
The primary materials are nitrile rubber and polyvinyl chloride (PVC), formulated through advanced manufacturing processes including sulfuration and foaming.
What is the thermal conductivity of this insulation material?
The thermal conductivity varies by temperature: ≤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 as tested per ASTM C 518 standards.
What temperature range can this insulation material handle?
The material is designed to operate effectively within a temperature range of -50°C to 110°C, making it suitable for a wide range of industrial and commercial applications.
How does the closed cell structure benefit the insulation performance?
The closed cell structure creates an effective barrier that prevents water vapor penetration, reducing the risk of moisture absorption and prolonging the service life of the insulation.
What is the fire rating and safety performance of the material?
The insulation features high safety performance with a Fire Rating of Class 0 & Class 1 (BS 476 Part 6 & 7) and a Flame Spread / Smoke Developed Index of 25/50 (ASTM E 84).
Is the insulation material resistant to environmental factors and mold?
Yes, it demonstrates good resistance to fungi (ASTM 21), ozone (GB/T 7762-1987), and weather/U.V. radiation (ASTM G23), ensuring long-term durability outdoors and indoors.
