Product Description

Insulation Material
Flexible Insulation
Thermal Insulation
  • Insulation that maintains its flexibility at very low temperatures down to -200℃ to +125℃.
  • Reduces the risk of corrosion under insulation.
  • Protects against mechanical impact and shock.
  • Low thermal conductivity.
  • Low glass transition temperature.
  • Easy installation even for complex shapes.

Cryogenic Rubber Foam is highly durable and resistant to wear and tear. It is resistant to moisture, chemicals, and UV radiation, making it suitable for use in both indoor and outdoor environments.

Frequently Asked Questions
What is the temperature range of the Cryogenic Rubber Foam?
The Cryogenic Rubber Foam maintains its exceptional flexibility at extremely low temperatures ranging from -200°C up to +125°C for the ULT class, and from -50°C to +105°C for the LT class.
Does this insulation prevent corrosion under insulation (CUI)?
Yes, our Cryogenic Rubber Foam has a high closed-cell structure (>95%) and a built-in water vapor barrier, which significantly reduces the risk of moisture penetration and corrosion under insulation (CUI).
Is it suitable for outdoor environments?
Absolutely. The foam material is highly durable and exhibits excellent resistance to wear, tear, chemicals, moisture, and UV radiation, making it suitable for both indoor and outdoor applications.
Can it be installed on complex shapes?
Yes, the material features high flexibility and a low glass transition temperature, ensuring easy installation and customized fitting even for complex pipeline configurations and shapes.
What are the core differences between the ULT and LT base materials?
The ULT (Ultra-Low Temperature) class is designed for extreme cryogenic applications down to -200°C, features a density range of 60-80Kg/m³, and maintains lower thermal conductivity at lower temperatures. The LT (Low Temperature) class is optimized for temperatures down to -50°C and has a density range of 40-60Kg/m³.
