What is Elastomeric Foam Insulation? Essentially, elastomeric foam insulation is a synthetic rubber composed of a closed-cell structure available in factory-made tubes, sheets, or rolls. The outside edge consists of a smooth surface or “skin” which serves as a built-in vapor retarder. Due to elastomeric foam’s flexible nature, it is less susceptible to cracks, breakage, and material loss when compared to rigid insulation options such as cellular glass, polyiso and phenolic foam. Finally, it’s also fiber-free and low-VOC for chemical emissions.阿

Frequently Asked Questions (FAQ)
What is the operating temperature range for these rubber insulation products?
Our rubber insulation products are designed to operate efficiently within a temperature range of -50°C to 110°C, making them highly versatile for various industrial and commercial systems.
What fire ratings does the insulation material achieve?
The material is highly fire-resistant, meeting Class 0 & Class 1 fire ratings under the BS 476 Part 6 & Part 7 test standards. It also features a low smoke and flame spread index of 25/50 according to ASTM E 84.
How does this rubber insulation perform against water and moisture?
It offers exceptional water resistance with a high water vapor permeability resistance value (μ ≥ 10,000) and low water absorption of 20% by volume. This prevents moisture accumulation and protects underlying systems.
Are these insulation products resistant to environmental factors like UV and Ozone?
Yes. The technical specifications indicate good resistance to UV rays, weathering, and ozone under ASTM and GB testing standards, ensuring durability in diverse outdoor climates.
What size and thickness configurations are available?
We supply rolls with thicknesses ranging from 1/4" (6mm) to 2" (50mm). Width options include standard 1.0m, 1.2m, and 1.5m widths to accommodate different duct and pipe dimensions.
Is this insulation material resistant to mold and fungal growth?
Yes, the material exhibits excellent fungi resistance tested under the ASTM G21 standard, ensuring a cleaner, safer, and mold-free environment.
