Frequently Asked Questions
What are the main benefits of rubber foam insulation rolls and sheets?
Rubber foam insulation offers key advantages including easy installation, outstanding moisture resistance, and a closed-cell structure that effectively blocks thermal conduction. It is also manufactured cleanly without the use of CFCs or HCFCs.
How does the closed-cell structure prevent thermal conduction?
The closed-cell structure traps tiny pockets of air, restricting air movement and minimizing heat transfer. It achieves low thermal conductivity, varying from ≤0.030 W/(m.k) at -20°C to ≤0.036 W/(m.k) at 40°C.
What temperature range can this insulation material withstand?
Our insulation material is designed to operate safely within a broad temperature range from -50°C to 110°C, making it highly versatile for various piping and equipment applications.
What fire safety standard credentials does the material possess?
The materials are tested under strict criteria, achieving Class 0 & Class 1 fire ratings according to BS 476 Part 6 & 7 standards. It also meets the ASTM E 84 standard with a Flame Spread / Smoke Developed index of 25/50.
How resistant is the material to environmental factors like U.V. and mold?
According to specialized test methods (such as ASTM G23 for UV and ASTM 21 for fungi), this rubber foam material exhibits excellent (Good) resistance to mold, fungi, ozone, and weathering.
