Frequently Asked Questions
1. What is the thermal conductivity of this rubber foam sheet?
The material features low and stable thermal conductivity, rated at 0.034 W/m.k generally, and ranges from ≤0.030 W/(m.k) at -20°C to ≤0.036 W/(m.k) at 40°C as tested under ASTM C 518.
2. Does the rubber foam sheet offer reliable fire protection?
Yes. It has a Class 0 & Class 1 Fire Rating according to BS 476 Part 6 & 7 standards. It also achieves an oxygen index of ≥36 (GB/T 2406, ISO4589) and limits Flame Spread and Smoke Development to a 25/50 index (ASTM E 84).
3. What are the common applications for these sheets?
These sheets are widely implemented in wall planking sound isolation, air duct sound absorption, acoustic decoration in entertainment facilities, and shock/pressure absorption for heavy instruments and equipment.
4. How resistant is the material to moisture and water vapor?
The rubber foam sheet demonstrates highly effective water resistance with a low water absorption rate (20% by volume via ASTM C 209) and extremely low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa) via DIN 52 615).
5. What dimensions and thicknesses are available for the sheets?
Thicknesses range from 1/4" (6mm) up to 2" (50mm). Standard roll widths are offered in 1m, 1.2m, and 1.5m versions, with roll lengths varying based on thickness requirements to optimize coverage.
6. How does the product perform under harsh environmental conditions?
It offers excellent durability and stability. The sheet has proven "Good" resistance ratings against fungi growth (ASTM 21), ozone breakdown (GB/T 7762-1987), and long-term exposure to UV radiation and weathering (ASTM G23).
