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 components, food packaging and food-grade scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of food-grade flowable Part A and Part B, formulated with food-grade raw materials and safety modifiers, featuring food contact compliance, non-toxic, odorless, fine uniform closed-cell structure, good elasticity and food-grade stability. It complies with FDA 21 CFR 177.2600 and LFGB standards, 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-grade components, food contact buffers and food packaging scenarios.

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