Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low-viscosity high-flow core product, specially developed for complex molds, fine structures and easy-pouring 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 and high-flow additives, featuring ultra-low viscosity, excellent flowability, fine uniform closed-cell structure, good elasticity and flow stability. It has a viscosity of ≤5000 mPa·s, easy to pour, can fill complex molds and fine structures completely, effectively solving the problem of traditional foaming materials’ high viscosity and poor flowability in complex mold scenarios. Compatible with most of our precision and electronic products, it is ideal for fine-structure components, complex mold pouring and easy-processing scenarios.
