Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-flowability easy casting core product, specially developed for complex molds, precision casting and thin-walled component environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with flowability modifiers and casting aids, featuring ultra-high flowability, easy casting, fine uniform closed-cell structure, good elasticity and flow stability. It has a viscosity of ≤5000 mPa·s at 25℃, good fluidity, can fill complex molds and thin-walled gaps without dead corners, effectively solving the problem of traditional foaming materials’ poor flowability in precision casting scenarios. Compatible with most of our precision and mold products, it is ideal for precision casting components, thin-walled buffers and complex mold casting scenarios.
