Wholesale Kingflex foam rubber pipe insulation Supplier, Factories

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
What are the available thicknesses and dimensions for these rubber insulation rolls?

The rubber insulation rolls come in thicknesses ranging from 1/4" (6mm) up to 2" (500mm). The standard width options are 1m, 1.2m, and 1.5m, with varying lengths to yield coverage from 4 to 45 square meters per roll depending on the thickness.

What temperature range can this insulation material withstand?

This insulation material functions reliably within a temperature range of -50°C to 110°C, making it highly effective for both extreme heating and cooling applications.

How does the water vapor permeability affect performance?

With a water vapor permeability rating of ≤0.91×10 ﹣¹³ Kg/(m.s.pa), the material acts as an excellent moisture barrier, preventing condensation build-up and ensuring long-lasting thermal efficiency.

What are the fire safety ratings for this rubber insulation?

The product holds a Class 0 and Class 1 fire rating in compliance with BS 476 Part 6 & Part 7, and meets the 25/50 Flame Spread and Smoke Developed Index standards of ASTM E 84.

Is this material resistant to mold and UV exposure?

Yes, it demonstrates high resistance to fungi growth (ASTM 21), ozone (GB/T 7762-1987), and weathering/U.V. radiation (ASTM G23), ensuring high durability even in harsh outdoor environments.

What is the density of this rubber insulation product?

According to ASTM D1667 test standards, the density range is 45-65Kg/m³, providing optimal balance between structural stability and flexibility.
