Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a food-grade safety food contact core product, specially developed for food packaging, food processing equipment and food contact environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with food-grade raw materials and non-toxic modifiers, featuring food-grade compliance, non-toxic, odorless, fine uniform closed-cell structure, good elasticity and food safety stability. It complies with FDA 21 CFR §177.2600 and EU 10/2011, no harmful substances, no odor, effectively ensuring food safety, 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.
