How to Use
1. Take Part A and Part B according to 1:1 weight ratio, use food-grade mixing tools, stir separately 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 pore uniformity and food safety).
3. Pour the mixture into food contact mold (paired with food grade mold silicone), foam and cure at room temperature or by heating.
4. After full curing, sanitize the product (high-temperature or chemical sanitization), it is ready for use in edible contact scenarios, ensuring food safety.
Application Scenarios
Focus on food contact scenarios: Food processing equipment sealing (paired with food grade mold silicone), food packaging auxiliary parts (paired with liquid tank silicone), edible contact shock absorption pads (paired with Industrial mold silicone rubber), food storage equipment filling (paired with liquid tank silicone), and food-grade robot components (paired with robot silicone). It helps food industry buyers improve product 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), meeting the food-grade procurement requirements of B2B buyers in food processing, packaging and other industries, facilitating export to global food markets.
