Product Description

ULT insulation material application
Flexible ULT insulation system details
Low temperature insulation details
Insulation material flexibility performance
  • Insulation that maintains its flexibility at very low temperatures down to -200℃ to +125℃
  • Reduces the risk of crack development and propagation
  • 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
  • Without fiber, dust, CFC, HCFC
ULT insulation system barrier performance
Flexible ULT insulation system does not need to install moisture barrier. Due to the unique closed cell structure and polymer blend formulation. LT low elastomeric materials have been highly resistant to water vapor permeation. This foamed material provides continuous resistance to moisture penetration throughout the thickness of the product.

Frequently Asked Questions
What is the temperature range capability of this ULT insulation?
The ULT insulation is designed to maintain its flexibility and performance at extremely low temperatures, ranging from -200℃ up to +125℃.
Does the flexible ULT insulation system require an additional moisture barrier?
No, it does not. Thanks to its unique closed cell structure and special polymer blend formulation, the material has high resistance to water vapor permeation, providing continuous resistance throughout its entire thickness.
How does this insulation help prevent corrosion and structural damage?
It significantly reduces the risk of crack development and propagation while minimizing the potential for corrosion under insulation (CUI). It also protects the systems from mechanical impact and shock.
What are the thermal conductivity properties of the ULT insulation?
The material features low thermal conductivity, measuring ≤0.028 W/(m.k) at -100°C and ≤0.021 W/(m.k) at -165°C, ensuring high thermal efficiency.
What certifications and test standards do your products comply with?
Our insulation products have successfully passed testing and obtained compliance for BS476, UL94, ROHS, REACH, FM, CE, and other international standards.
Does the material contain any harmful fibers or chemicals?
No. The material is environmentally friendly and clean, manufactured entirely without fiber, dust, CFCs, and HCFCs.
