Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high thermal conductivity heat dissipation core product, specially developed for thermal management, heat dissipation and high-temperature heat transfer scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with composite thermal conductive fillers and heat-dissipating modifiers, which are compounded with fibrous inorganic substances to form fluffy thermal conductive powder, constructing multi-level heat conduction channels that penetrate the foam pores, significantly improving heat dissipation efficiency. It has a thermal conductivity of ≥0.6 W/(m·K), low thermal resistance, efficient heat transfer, fine uniform closed-cell structure, good elasticity and thermal stability, effectively solving the problem of poor heat dissipation of traditional foaming materials due to foam pore thermal resistance. Compatible with most of our electronic and high-temperature products, it is ideal for heat dissipation gaskets, thermal management components and high-power heat transfer scenarios.
