Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a food-grade non-toxic core product, specially developed for food contact, food packaging and sterile food-related scenarios. 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 additives, featuring food-grade safety, non-toxic, tasteless, fine uniform closed-cell structure, good elasticity and safety stability. It meets FDA 21 CFR §177.2600 and LFGB certification, no harmful substances, can be in direct contact with food, effectively solving the problem of traditional foaming materials’ non-food-grade and toxic risks in food-related scenarios. Compatible with most of our food-grade and sterile products, it is ideal for food contact components, food packaging buffers and sterile food scenarios.

How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a clean, sterile container to eliminate sediment, ensure no impurities (avoid affecting food-grade safety).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure food-grade uniformity and closed-cell structure).
3. Pour the mixture into food contact component mold (paired with liquid tank silicone), foam and cure at room temperature or by heating in a sterile environment.
4. After full curing, the product is food-grade, non-toxic, ready for use in food contact, food packaging and sterile food scenarios.
Application Scenarios
Focus on food-related scenarios: Food packaging buffers (paired with liquid tank silicone), food contact components (paired with high-precision mold silicone), food processing equipment buffers (paired with Industrial mold silicone rubber), catering utensil linings (paired with high-precision mold silicone), and food storage protection (paired with liquid tank silicone). It helps food-industry buyers ensure food safety and meet food-grade standards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS food-grade certification, FDA 21 CFR §177.2600, LFGB certification, excellent food-grade and non-toxic performance, meeting the food-grade procurement requirements of B2B buyers in food processing, food packaging and catering industries, facilitating export to global markets.
Customization Options
Customizable food-grade level (meets more international food standards for high-demand scenarios), sterility level, foaming ratio and hardness, adapting to different food contact and food packaging requirements, helping buyers optimize food safety protection.
Production Process
Food-grade-oriented production process: High-purity food-grade Silicone raw materials → formula optimization (add non-toxic food-grade additives) → precision mixing in sterile workshop → food-grade test (FDA/LFGB) → sterility test → standardized curing → food safety inspection → packaging. Strict food-grade testing ensures product food contact safety and non-toxic performance.
