Insulation structure detail

The 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 of the ULT insulation system?
The ULT insulation system maintains its outstanding flexibility at extremely low temperatures, with an operational temperature range from -200℃ up to +125℃ (technical data specified at -200°C to +110°C).
Does this insulation require an additional moisture barrier?
No, it does not. The unique closed-cell structure and advanced polymer blend formulation make the material highly resistant to water vapor permeation, providing continuous moisture resistance throughout its entire thickness.
How does the insulation protect piping systems?
It significantly reduces the risk of crack development and propagation under low temperatures, prevents corrosion under insulation (CUI), and provides excellent defense against mechanical impacts and physical shocks.
Is the material environmentally friendly?
Yes, our insulation system is manufactured without the use of fibers, dust, CFCs, or HCFCs, making it clean, safe to install, and environmentally compliant.
What international standards and certifications do these products meet?
Our materials are fully tested and certified to comply with major global standards, including BS476, UL94, ROHS, REACH, FM, and CE regulations.
