Frequently Asked Questions

What dimensions and thicknesses are available for the insulation rolls?

The insulation rolls come in various thicknesses ranging from 1/4" (6mm) up to 2" (50mm), and are available in standard widths of 1m, 1.2m, and 1.5m to fit different application demands.

What is the operating temperature range of this material?

The material performs reliably within a wide temperature range of -50°C to 110°C, conforming to the GB/T 17794-1999 test standard.

How does the insulation rate in terms of fire and smoke safety?

It meets strict safety requirements, achieving Class 0 and Class 1 ratings under BS 476 Part 6 & 7, and a Flame Spread/Smoke Developed Index of 25/50 in ASTM E 84 testing.

Is the insulation material resistant to environmental factors and weather?

Yes, it demonstrates excellent (Good) resistance to UV, ozone, fungi growth, and general weathering, making it durable for demanding external conditions.

What are the primary applications of this elastomeric foam?

It is widely used in air conditioning, automotive components, machinery parts, sports and medical equipment, and architectural projects like supermarkets, exhibition centers, and stadium construction.

Why does it maintain its thermal conductivity over time?

Due to its excellent water resistance and extremely low water vapor permeability (≤0.91×10⁻¹³ Kg/(m.s.pa)), moisture does not easily penetrate the material, ensuring the thermal conductivity remains stable.
