Frequently Asked Questions
What are the primary differences between Kingflex ULT and Kingflex LT?
Kingflex ULT is designed for ultra-low cryogenic environments ranging from -200°C to 125°C, whereas Kingflex LT is engineered for low-temperature applications between -50°C to 105°C.
What is the thermal conductivity of Kingflex ULT at cryogenic temperatures?
Tested under ASTM C177, Kingflex ULT has a thermal conductivity of 0.028 W/(m·K) at -100°C and 0.021 W/(m·K) at -165°C, ensuring reliable performance in extreme cold conditions.
Why is the closed-cell area percentage important for cryogenic insulation?
Both Kingflex ULT and LT feature a closed-cell ratio greater than 95% (ASTM D2856). This high percentage effectively prevents moisture ingress and maintains long-term thermal efficiency in sub-zero environments.
What are the main applications of these insulation materials?
These materials are widely applied in liquefied natural gas (LNG) systems, petrochemical facilities, industrial gases processing, agricultural chemical pipelines, and other cryogenic equipment insulation projects.
How does Kingflex LT perform against water vapor transmission?
Kingflex LT boasts a water vapor permeability coefficient of 0.0039g/h.m² (for a 25mm thickness) and a wet resistance factor (μ) greater than 10,000, complying with ASTM E96 and EN12086 standards.
What are the standard dimensions available for Kingflex rolls?
The standard available sizes are 3/4" (20mm thickness) with dimensions of 10m x 1m (10㎡/roll) and 1" (25mm thickness) with dimensions of 8m x 1m (8㎡/roll).
