Technical Insulation Material
The impact from any part can be widely dispersed and attenuated by elastomer material, thus avoiding the risk of cracking due to stress concentration. Reducing the temperature change stress makes the cooling system superior to traditional materials such as foam glass, polyurethane PIR, and PUR.

Frequently Asked Questions
What are the advantages of elastomer insulation materials over traditional options like foam glass or PIR?
Elastomer materials widely disperse and attenuate physical impacts, eliminating cracking risks from stress concentration. In cooling systems, they outperform traditional choices like foam glass, PIR, and PUR by significantly reducing stress caused by temperature variations.
What temperature ranges are suitable for the ULT and LT base materials?
The ULT system is engineered for cryogenic and extreme applications, performing safely between -200°C and 125°C. The LT version is optimized for temperature environments ranging from -50°C to 105°C.
Does this insulation system require fiber-based expansion and contraction fillers?
No, the flexible ULT insulation system does not require fiber expansion or contraction fillers, which is a common requirement in typical rigid foam LNG piping applications.
What are the water vapor permeability characteristics of the LT base material?
The LT base material features a high wet resistance factor (μ > 10,000) and a very low water vapor permeability coefficient of 0.0039g/h.m² at a 25mm thickness, ensuring excellent defense against moisture intrusion.
What dimensions are available for this flexible insulation system?
The standard roll dimensions are available in two sizes: 3/4" (20mm thickness) in 10m x 1m rolls (10㎡/roll), and 1" (25mm thickness) in 8m x 1m rolls (8㎡/roll).
