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