Frequently Asked Questions (FAQ)

What are the primary fire safety ratings of this material?

This material features exceptional fire-resistance performance with Class 0 & Class 1 fire ratings under BS 476 Part 6 & 7 test standards. It also maintains a high oxygen index (≥36) and a low smoke density.

How does the thermal conductivity perform at different temperatures?

The material offers low thermal conductivity (K-value) to optimize thermal efficiency: ≤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.

Is this insulation material resistant to moisture and water vapor?

Yes, it features good moisture resistance and a water vapor permeability factor (μ) of ≥10000. It also shows a water absorption rate of 20% by volume under ASTM C 209 standards.

Can this material withstand outdoor environmental conditions?

Absolutely. The material has excellent resistance properties, including good resistance to ozone (GB/T 7762-1987), UV radiation, weather conditions (ASTM G23), and fungi growth (ASTM 21).

How can I place an order for customized dimensions?

To order customized products, please provide your drawing, technical parameters, and application environment details (including size, material type, hardness, and tolerance). We will provide a quotation and a sample check prior to mass production.
