Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a heat-insulating high-thermal-resistance core product, specially developed for thermal insulation equipment, high-temperature pipelines and heat-insulation scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with heat-insulating fillers and thermal resistance modifiers, featuring ultra-low thermal conductivity, excellent heat insulation, fine uniform closed-cell structure, good elasticity and thermal stability. It has a thermal conductivity of ≤0.03 W/(m·K), effectively blocking heat transfer, reducing heat loss, solving the problem of traditional foaming materials’ poor thermal insulation in high-temperature scenarios. Compatible with most of our thermal insulation products, it is ideal for heat-insulating components, thermal insulation buffers and heat-insulation scenarios.
