Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a low permeability gas/water barrier core product, specially developed for barrier packaging, gas/water proof and low-permeability environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with barrier modifiers and impermeable fillers, featuring ultra-low permeability, gas/water barrier, fine uniform closed-cell structure, good elasticity and barrier stability. It has a gas permeability of ≤5 cm³/(m²·24h·atm) and water vapor transmission rate of ≤3 g/(m²·24h), no gas/water leakage, effectively preventing gas and water penetration, solving the problem of traditional foaming materials’ high permeability in barrier scenarios. Compatible with most of our packaging and barrier products, it is ideal for barrier components, gas/water proof buffers and low-permeability scenarios.
