China NBR/PVC Rubber Foam Insulation For Cryogenic System Supplier, Quotes
Multi-layer composite structure: ULT for inner layer; LT for outer layer.
Main material: ULT—alkadiene polymer; color in Blue
LT—NBR/PVC; color in Black
The 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
Q: Does this low-temperature insulation system require an additional moisture barrier?
No, it does not. The unique closed-cell structure and polymer mix formulation of the nitrile butadiene rubber elastic foam provide outstanding, continuous resistance to water vapor penetration across the entire thickness of the material.
Q: What is the recommended operating temperature range for the ULT and LT grades?
The ULT Grade is designed to withstand extreme cold environments, operating efficiently between -200°C and 125°C. The LT Grade is recommended for temperatures ranging from -50°C to 105°C.
Q: What are the standard dimensions and sizes available for these insulation rolls?
The insulation is available in thickness specifications of 3/4" (20mm) with a roll size of 10m x 1m (10㎡/roll), and 1" (25mm) with a roll size of 8m x 1m (8㎡/roll).
Q: What are the key application areas for these insulation materials?
Common applications include low-temperature storage tanks, industrial gas and agricultural chemical production plants, platform piping, gas stations, and nitrogen plants.
Q: How well does this material resist moisture according to industry standards?
Both ULT and LT grades feature a closed cell ratio of over 95% (tested under ASTM D2856). The LT grade has a wet resistance factor (μ) of over 10,000 (tested under EN12086 / EN13469) and a low water vapor permeability coefficient of 0.0039g/h.m² (for a 25mm thickness).
Q: What is the thermal conductivity of the ULT grade at extremely low temperatures?
Based on the ASTM C177 test standard, the ULT grade maintains a low thermal conductivity of 0.028 W/(m·K) at -100°C and decreases to 0.021 W/(m·K) at -165°C, ensuring high thermal performance.
