How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a clean, food-safe 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 food residue).
3. Pour the mixture into food contact component mold (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating (heating helps enhance food safety stability).
4. After full curing, conduct food contact test (no harmful migration) to confirm qualification, then use in food processing and food contact scenarios.
Application Scenarios
Focus on food contact scenarios: Food processing equipment food-safe buffers (paired with industrial mold silicone rubber), food packaging contact parts (paired with high-precision mold silicone), food-safe packaging (paired with Liquid Tank Silicone), food processing machinery components (paired with industrial mold silicone rubber), and food contact robot parts (paired with robot silicone). It helps food processing and food packaging 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 food contact certification, excellent food safety performance, meeting the food contact procurement requirements of B2B buyers in food processing, food packaging and food contact industries, facilitating export to global markets.
Customization Options
Customizable food contact certification (additional EU food contact certifications for high-demand scenarios), food safety stability (≥98% for high-demand scenarios), foaming ratio and hardness, adapting to different food contact and food processing requirements, helping buyers meet global food safety standards.
Production Process
Food contact-oriented production process: High-purity food-grade Silicone raw materials → formula optimization (add non-toxic modifiers) → precision mixing (clean, food-safe environment) → food contact test → FDA/LFGB certification test → standardized curing → food safety stability inspection → food-grade packaging. Strict food safety testing ensures product food contact grade and food safety.
