When producing molds that contact food, safety is non-negotiable. Our food-grade platinum silicone is formulated to meet the rigorous standards of FDA 21 CFR 177.2600, ensuring it's safe for repeated contact with chocolate, candy, baked goods, and ice.

The Food Safety Difference:

Unlike cheaper peroxide-cured silicones that can leave residues and odors, our platinum-cure system uses a pure catalyst that creates no harmful by-products. The result is a material that imparts absolutely no taste or smell to your food products—critical for delicate chocolates and confections where flavor purity is paramount.

Key Performance Benefits:

  • FDA Certified: Full compliance documentation available, giving you and your customers complete confidence in food safety.
  • Superior Release Properties: Chocolates release with a glossy, professional finish without spraying or wiping with oil. Candy doesn't stick, and ice cubes pop out effortlessly.
  • Thermal Versatility: Withstands temperatures from freezer conditions (-50°C) to oven heat (250°C), suitable for diverse applications from ice cube trays to baking molds.
  • Long-Term Durability: Maintains release properties and mechanical integrity through hundreds of cycles and dishwasher washes.
  • Stain Resistance: Formulated to resist staining from colored foods like berry candies and colored chocolates.

For Food-Grade Mold Production:
1. Clean Equipment: Ensure all mixing containers and tools are clean and food-safe.
2. Mix Thoroughly: Combine Parts A and B at 1:1 ratio, mixing gently but completely for 2-3 minutes.
3. Pour Carefully: Pour into mold frame with master model, avoiding bubble introduction.
4. Room Temperature Cure: Allow to cure at room temperature for 3-5 hours.
5. Post-Cure for Food Use: For optimal food contact safety, post-cure molds at 80°C for 2 hours before first use.
6. Wash Before Use: Clean finished molds with mild soap and warm water before food contact.

FAQ:

Q1: Can you provide FDA certification documents for my regulatory files?
A: Yes, we provide compliance statements and test reports confirming FDA 21 CFR 177.2600 compliance with every order. Additional documentation available upon request.

Q2: Is this silicone safe for boiling water or commercial dishwasher use?
A: Yes, it's heat resistant to 250°C, making it safe for boiling water, commercial dishwashers, and ovens. The material maintains integrity through repeated high-temperature cleaning.

Q3: Will this silicone stain from colored candy mixtures?
A: Our food-grade formulation is resistant to staining from most food colors. For heavily pigmented products, we recommend testing and prompt cleaning after use.

Q4: What's the recommended hardness for chocolate molds?
A: Shore A 15-20 is ideal for chocolate work—soft enough for easy demolding of detailed pieces, firm enough to maintain shape during production.

Q5: How long will food-grade molds last in commercial production?
A: With proper care, 5,000-10,000+ cycles depending on application. Chocolate molds typically last longer than gummy molds due to less abrasive materials.
