China NBR/PVC Rubber Foam Insulation For Cryogenic System Manufacturer, Supplier
Multi-layer composite structure: ULT for inner layer; LT for outer layer.
Main material: ULT—alkadiene polymer; color in Blue
LT—NBR/PVC; color in Black
Kingflex flexible ultra-low temperature insulation system does not require a moisture barrier. Thanks to the unique closed cell structure and polymer mix formula, the elastic foam material of nitrile butadiene rubber has a high resistance to water vapor penetration. This foam material provides continuous resistance to moisture penetration throughout the thickness of the product.

Frequently Asked Questions (FAQ)
Why does this ultra-low temperature insulation system not require a moisture barrier?
It utilizes a unique closed-cell structure and polymer mix formula with elastic nitrile butadiene rubber foam, which features a high inherent resistance to water vapor penetration, eliminating the need for an external moisture barrier.
What is the recommended operating temperature range for these materials?
The ULT base material supports operating temperatures from -200°C to 125°C, while the LT base material is designed for temperatures between -50°C to 105°C.
What are the primary applications of this insulation system?
It is ideal for low temperature storage tanks, industrial gas and agricultural chemical production plants, platform pipes, gas stations, and nitrogen plants.
What is the closed-cell percentage of the insulation?
Both the ULT and LT base materials feature a closed-cell percentage of greater than 95%, ensuring reliable thermal conductivity and resistance to moisture.
What test standards are used for testing thermal conductivity?
The thermal conductivity properties are verified and tested using the ASTM C177 standard method.
