Frequently Asked Questions (FAQ)

What are the main advantages of using closed cell rubber insulation sheets?

Closed cell rubber insulation sheets provide excellent thermal and acoustic insulation. The closed cell structure prevents moisture penetration, exhibits outstanding flame resistance, resists deformation under pressure, and has extremely low thermal conductivity.

Is this insulation material environmentally friendly and safe for indoor use?

Yes, this rubber insulation sheet is designed with environmental safety in mind. It is completely formaldehyde-free, fiber-free, dust-free, and has low VOCs (volatile organic compounds), making it highly resistant to mold and mildew growth.

What temperature range can this rubber insulation sheet withstand?

The product performs efficiently within a service temperature range of -50°C to 110°C, conforming to testing standard GB/T 17794-1999.

What are the fire safety ratings of this material?

This material has been certified for fire performance, achieving Class 0 & Class 1 ratings based on BS 476 Part 6 and Part 7 tests. It also has a low Flame Spread and Smoke Developed Index of 25/50 according to ASTM E 84.

What sizes and thicknesses are available for the insulation sheets?

The sheets are available in thicknesses from 1/4" (6mm) up to 2" (50mm). Standard widths are 1m, 1.2m, and 1.5m, with varying lengths to optimize coverage area per roll.
