Product Description

Flexible ultra-low temperature insulation system does not require a moisture barrier. Thanks to the unique closed cell structure and polymer mix formula, the elastic foam material of nitrile butadiene rubber has a high resistance to water vapor penetration. This foam material provides continuous resistance to moisture penetration throughout the thickness of the product.

Frequently Asked Questions

Does this low temperature insulation system require a separate moisture barrier?

No, it does not require a separate moisture barrier. The elastic foam material made of nitrile butadiene rubber has a unique closed cell structure and a polymer mix formula that provides built-in, continuous resistance to water vapor penetration.

What are the recommended operating temperatures for the ULT and LT grades?

The ULT Grade is recommended for temperatures ranging from -200°C to 125°C, making it suitable for ultra-low cryogenic systems. The LT Grade is recommended for operating temperatures from -50°C to 105°C.

What is the closed-cell percentage of this insulation foam?

Both the ULT and LT grades have a closed-cell ratio of greater than 95% (tested under ASTM D2856), which ensures outstanding resistance to moisture absorption and excellent thermal performance.

Where is this ultra-low temperature insulation typically applied?

Common applications include low-temperature storage tanks, industrial gas plants, agricultural chemical production plants, platform piping, gas stations, and nitrogen plants.

How does the thermal conductivity change at cryogenic temperatures for the ULT grade?

According to the ASTM C177 test method, the thermal conductivity of the ULT grade is 0.028 W/(m·K) at -100°C, and it decreases to an even lower 0.021 W/(m·K) at -165°C.

What are the tensile and compressive strengths of the ULT grade?

Tested under ASTM D1623, the tensile strength is 0.30 Mpa at -100°C and 0.25 Mpa at -165°C. Under ASTM D1621, the compressive strength is ≤0.3 Mpa at -100°C.
