Explore our premium engineered, high-density closed-cell insulation materials tailored specifically for heavy industrial applications, mechanical HVAC systems, and low-temperature projects.
An in-depth look at cryogenic thermal dynamics, mechanical vapor barrier engineering, and material lifecycle longevity at -162°C (-260°F).
Liquefied Natural Gas (LNG) must maintain a constant temperature around -162°C to remain in a liquid state. Ambient heat penetration into pipeline arrays results in the vaporization of LNG, commonly known as Boil-Off Gas (BOG). Controlling this heat leak requires thermal insulation materials with incredibly low thermal conductivity (K-value) at cryogenic temperatures.
Traditional elastomeric foam is augmented via specialized NBR/PVC formulations to remain stable under severe thermal contraction. The closed-cell matrix prevents moisture migration, which would otherwise crystallize into ice, causing structural failure and an exponential increase in K-value.
One of the costliest hazards in cryogenic facility maintenance is Corrosion Under Insulation (CUI). When ambient atmospheric moisture permeates insulation layers and meets cold pipeline steel, water condenses and freezes. Because ice takes up more volume than liquid water, it creates internal mechanical pressure, fracturing the cellular structure of insulation materials.
By leveraging Kingflex Closed-Cell Rubber Foam with a vapor permeability resistance factor (µ) of >10,000, industrial operators establish a permanent, integrated moisture barrier. This eliminates the necessity of additional metallic vapor barrier wraps, significantly lowering overall material and labor costs.
