Frequently Asked Questions (FAQs)
What is the recommended operating temperature range for Cryogenic Rubber Foam?
Depending on the grade, the ULT Grade is recommended for extreme environments operating from -200°C up to 125°C, while the LT Grade is optimized for temperature ranges between -50°C and 105°C.
How does Cryogenic Rubber Foam prevent corrosion under insulation (CUI)?
With a high percentage of closed cell areas (>95%) and superior wet resistance, the material prevents moisture intrusion and condensation on the cold surfaces, drastically minimizing the risk of corrosion under insulation.
Does this insulation maintain flexibility in extreme cold?
Yes. Unlike rigid insulation materials, Cryogenic Rubber Foam is designed to retain its elasticity and flexibility at temperatures as low as -200°C. This greatly reduces the risk of crack formation and stress-induced propagation.
What are the standard densities for the ULT and LT grades?
The ULT Grade features a density range of 60-80 Kg/m³, designed for heavy-duty ultra-low applications. The LT Grade has a density range of 40-60 Kg/m³ to cover standard low-temperature requirements.
How does Cryogenic Rubber Foam react to mechanical impact?
Its elastomeric closed-cell structure operates as a cushion that absorbs mechanical impacts and shocks, protecting both the pipework and the insulation barrier from physical damage during operations.
What testing standards are used to measure the material properties?
The insulation properties are tested in compliance with globally recognized testing methods, including ASTM C177 for thermal conductivity, ASTM D1622 for density, and ASTM D1623 for tensile strength.
