How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a clean 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 structure and food safety, avoid food residue accumulation).
3. Pour the mixture into food contact component mold (paired with liquid tank silicone), foam and cure at room temperature or by heating (heating helps enhance food safety stability).
4. After full curing, clean the product (no residue), test food safety (FDA compliant) to confirm qualification, then use in food contact and food processing scenarios.
Application Scenarios
Focus on food-related scenarios: Food contact buffers (paired with liquid tank silicone), food packaging parts (paired with high-precision mold silicone), food processing equipment components (paired with Industrial mold silicone rubber), catering tool buffers (paired with robot silicone), and food-grade robot parts (paired with robot silicone). It helps food industry buyers ensure food safety and meet food-grade compliance requirements.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, FDA 21 CFR §177.2600 certification, SGS food-grade certification, excellent food safety, 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 compliance (additional EU food contact certification for high-demand scenarios), hardness, foaming ratio and color (food-grade colorants), adapting to different food contact and 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 (add non-toxic modifiers) → precision mixing (clean environment) → food safety test (FDA standard) → non-toxicity test → standardized curing → food safety stability inspection → food-grade packaging. Strict food safety testing ensures product FDA compliance and food contact safety.
