Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a food-grade direct contact core product, specially developed for direct food contact, food processing and food packaging environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, made of high-purity food-grade raw materials and formulated with food-safe additives, featuring FDA compliance, non-toxic, tasteless, fine uniform closed-cell structure, good elasticity and food safety stability. It is compliant with FDA 21 CFR 177.2600, non-toxic, tasteless, no harmful substances, safe for direct food contact, effectively solving the problem of traditional foaming materials’ non-compliance in food contact scenarios. Compatible with most of our food-grade products, it is ideal for food contact components, food-safe buffers and food packaging scenarios.
