Frequently Asked Questions

What are the main advantages of using these Rubber Foam Sheets?

These sheets offer a low and stable thermal conductivity of 0.034w/m.k, exceptionally low water absorption rates, and outstanding fireproof and soundproof features. Additionally, they exhibit excellent flexibility, robust aging resistance, and strong vibration resistance.

What applications are Rubber Foam Sheets best suited for?

They are widely applied in sound isolation for wall planking, sound absorption inside air ducts, acoustic treatment in entertainment spaces, as well as providing shock absorption and pressure relief in sensitive equipment and instruments.

What is the thermal conductivity rating of the sheet under different temperatures?

According to standard ASTM C 518 tests, the thermal conductivity values are: ≤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.

What fire ratings do these foam sheets comply with?

The rubber foam sheet meets Class 0 and Class 1 fire rating standards in accordance with BS 476 Part 6 & Part 7, boasting an oxygen index of ≥36 and a Flame Spread & Smoke Developed Index of 25/50 under ASTM E 84.

Do they perform well under outdoor conditions, UV, and moisture?

Yes, they show excellent resistance to UV, weathering (ASTM G23), and ozone (GB/T 7762-1987). With a low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)) and high water resistance, they are highly reliable in high-humidity or outdoor environments.
