Frequently Asked Questions (FAQ)
What are the primary applications of Cryogenic Rubber Foam?
Cryogenic Rubber Foam is specifically designed for thermal insulation in low-temperature environments. It is ideal for cryogenic tanks, pipelines, cold storage equipment, and other industrial cold-preservation systems.
What is the difference between Kingflex ULT and Kingflex LT?
Kingflex ULT is engineered for ultra-low temperature applications ranging from -200°C to 125°C, with higher density and exceptional low-temp thermal conductivity. Kingflex LT is designed for moderate low-temperature applications ranging from -50°C to 105°C.
Does this insulation require an additional moisture barrier?
No. The material has a built-in moisture-proof feature due to its closed-cell structure (exceeding 95% closed cells), which naturally prevents moisture penetration without the need for extra barriers.
Why is the closed-cell structure important for cryogenic systems?
A high closed-cell ratio (above 95%) significantly restricts heat transfer and prevents water vapor absorption. This maintains long-term thermal efficiency and prevents condensation or ice formation on low-temperature pipelines.
Is the cryogenic rubber foam safe and environment-friendly?
Yes. The material is formulated without fiber, dust, CFCs, and HCFCs, making it safe to handle and environmentally sustainable during its entire service life.
