Flexible ultra low temperature insulation system does not need to install moisture-proof layer. Due to its unique closed cell structure and polymer blend formulation, low temperature elastomeric foam material have been highly resistant to water vapor permeation. This foam material provides continuous resistance to moisture penetration throughout the entire thickness of the product.

Flexible ULT insulation system does not require the use of fiber materials as expansion and expansion fillers. (This type of construction method is typical on rigid foam LNG pipes.) On the contrary, it is only necessary to install the low temperature elastomeric material in each layer according to the recommended reserved length to solve the expansion joint problem required by the conventional system. The elasticity at low temperatures gives the material the characteristics of expansion and shrinkage in the longitudinal direction.
