Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a low-viscosity core product, specially developed for complex molds, thin-walled components and high-flow-required scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-viscosity modifiers, featuring ultra-low viscosity, high fluidity, fine uniform closed-cell structure, good elasticity and flow stability. It has a viscosity of ≤5000 mPa·s at 25℃, can easily flow into complex mold cavities and thin-walled gaps, no dead corners, ensuring uniform foaming and full filling, effectively solving the problem of traditional foaming silicone’s poor fluidity. Compatible with most of our precision and electronic products, it is ideal for precision casting, electronic components and complex mold scenarios.
