Our products reach Class 0 and Class 1 ratings when tested in accordance with BS 476 Part 6 and Part 7 standards. They also show a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
The products are suitable for temperature ranges between -50°C and 110°C, making them ideal for both hot and cold medium containers and HVAC systems.
Yes, our materials exhibit excellent resistance to U.V. and weather (under ASTM G23), ozone (GB/T 7762-1987), and fungi growth (ASTM 21).
Yes. While we offer a wide range of standard thicknesses (from 1/4" to 2") and widths (1m, 1.2m, and 1.5m), we can also provide design and sampling services for your nonstandard OEM requirements.
This insulation is widely utilized in HVAC systems, construction/workshop insulation, sound absorption, sports gear padding, and controlled environments such as medical, automotive, pharmaceutical, and electronic factories.
The material maintains low thermal conductivity values: ≤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.
