Frequently Asked Questions

Q What are the main raw materials used in your rubber foam sheets?
Our rubber foam thermal insulation materials are mainly produced using high-performance Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) as main components, processed via sophisticated foaming, sulfuration, and ban burying procedures.
Q What is the standard operating temperature range for these sheets?
These rubber foam insulation sheets can operate safely and maintain high structural and thermal integrity under a wide temperature range from -50°C up to 110°C.
Q What are the fire safety classifications for this insulation material?
The material holds Class 0 and Class 1 fire ratings according to BS 476 Part 6 & 7 test methods, and complies with ASTM E 84 with a Flame Spread and Smoke Developed Index of 25/50.
Q How does the aluminum foil cladding improve sheet performance?
The aluminum foil acts as an extra protective layer that enhances moisture resistance, improves UV and weather resistance, increases mechanical durability, and reflects radiant heat for overall better thermal efficiency.
Q Are these rubber foam sheets resistant to environmental factors like ozone and UV?
Yes, our rubber foam sheets offer excellent resistance properties against fungi (ASTM 21), ozone (GB/T 7762-1987), and U.V./weather degradation (ASTM G23), making them highly durable.
