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, kitchen appliances and food-grade 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 FDA and LFGB dual certification, non-toxic, odorless, tasteless, fine uniform closed-cell structure, good elasticity and food safety stability. It meets the strict requirements of food contact materials, no harmful substances precipitation, 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-grade components, food-contact buffers and food-grade scenarios.

How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a sterile food-grade environment to eliminate sediment, ensure no impurities (avoid affecting food safety).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform food safety and closed-cell structure, no residue).
3. Pour the mixture into food-grade component mold (paired with food-grade mold silicone), foam and cure at room temperature or by heating (heating helps enhance food safety stability).
4. After full curing, test food safety compliance (FDA & LFGB) to confirm qualification, then use in food-contact and food-grade scenarios.
Application Scenarios
Focus on food-grade scenarios: Food contact buffers (paired with food-grade mold silicone), kitchen appliance food-contact parts (paired with liquid tank silicone), food packaging (paired with liquid tank silicone), food processing equipment components (paired with high-precision mold silicone), and food-grade robot parts (paired with robot silicone). It helps food and kitchen appliance industry buyers ensure food safety and meet food contact standards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, FDA 21 CFR §177.2600, LFGB certification, SGS food-grade certification, fully compliant with food contact material standards, meeting the food-grade procurement requirements of B2B buyers in food, kitchen appliance and food-contact industries, facilitating export to global markets.
Customization Options
Customizable food-grade compliance (additional EU food contact standards for high-demand scenarios), foaming ratio and hardness, adapting to different food-contact requirements, helping buyers optimize food safety compliance effect.
Production Process
Food-grade-oriented production process: High-purity food-grade Silicone raw materials → formula optimization (add non-toxic food-grade additives) → precision mixing (sterile environment) → food-grade test (FDA & LFGB) → safety inspection → standardized curing → food safety stability inspection → food-grade sterile packaging. Strict food safety testing ensures product compliance with food contact standards.
