Kingflex
1 / 1
Kingflex 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.

No, it does not. The elastic foam material is made of nitrile butadiene rubber with a unique closed-cell structure and polymer mix formula, which provides continuous, high resistance to water vapor penetration through the entire thickness of the product.
The recommended operating temperature for Kingflex ULT ranges from -200°C to 125°C, making it highly suitable for extreme cryogenic applications.
The material features a closed-cell rate of over 95% (tested under ASTM D2856), which prevents moisture migration and maintains long-term thermal efficiency.
It is designed for industrial applications including low-temperature storage tanks, agricultural chemical production plants, gas stations, nitrogen plants, and platform piping systems.
According to ASTM C177 test standards, the thermal conductivity of Kingflex ULT is 0.028 W/(m·K) at -100°C and decreases to 0.021 W/(m·K) at -165°C.
