Wholesale Dienes Rubber Foam Insulation For the Cryogenic Systems Supplier, Suppliers

These are flexible, closed-cell, rubber foams based on dienes rubber. Flexible elastomeric foams exhibit such a high resistance to the passage of water vapour that they do not generally require additional water-vapour barriers. Such high vapour resistance, combined with the high surface emissivity of rubber, allows flexible elastomeric foams to prevent surface condensation formation with comparatively small thicknesses.

Frequently Asked Questions
What is the temperature range for Kingflex Cryogenic Rubber Foam?
Kingflex Cryogenic Rubber Foam provides exceptional thermal performance at extreme temperatures. Kingflex ULT is designed for temperatures ranging from -200°C to 125°C, while Kingflex LT operates effectively between -50°C to 105°C.
Does this cryogenic foam maintain its flexibility in extreme cold?
Yes, one of the primary features of Kingflex Cryogenic Rubber Foam is its ability to maintain high flexibility at very low temperatures down to -200°C, preventing cracking and structural failure.
How does the insulation perform against moisture and chemicals?
With a closed-cell structure of over 95%, it provides excellent resistance to moisture absorption, water vapor permeability, chemicals, and UV radiation, making it suitable for both harsh indoor and outdoor environments.
What are the standard sizes and dimensions available?
The product comes in rolls with standard sizes. These include 3/4" (20mm thickness) rolls measuring 10m x 1m (10㎡ per roll), and 1" (25mm thickness) rolls measuring 8m x 1m (8㎡ per roll).
What is the thermal conductivity of Kingflex ULT?
Kingflex ULT has a thermal conductivity rating of 0.028 W/(m·K) at -100°C and 0.021 W/(m·K) at -165°C under the ASTM C177 test method, ensuring optimal energy savings.
Is the material environmentally stable and corrosion-resistant?
Yes, it has a neutral to slightly alkaline pH value of ≥8.0 (tested under ASTM C871), which helps prevent corrosion under insulation (CUI) on copper or steel piping.
