How to choose food grade silicone raw materials? 5 major standard factory direct supply guide
Five major screening criteria for food-grade silicone raw materials
Authoritative certification: FDA (USA), LFGB (EU) certification is the bottom line for safety;
Temperature resistance: -40℃~250℃ no deformation, no precipitation (third-party test report available);
Tear strength: ≥25kN/m (to ensure the service life of the mold);
Zero odor residue: platinum vulcanization process is used to eliminate sulfide pollution;
Batch stability: full process automated production, color difference and hardness error <3%.
- Actual combat case: How do well-known brands select materials?
Case 1: A pacifier project of an international maternal and child brand requires 100,000 tensile tests without damage. We achieved the goal by adjusting the proportion of phenyl silicone oil;
Case 2: Baking mold customers proposed “-50℃ quick freezing without cracking”, the factory customized a high elasticity formula, and the customer repurchase rate increased by 90%.
- FAQ
Q: Why are the prices of food-grade silicone raw materials so different?
A: The main reasons are the purity of raw materials (such as fumed silica) and process cost (platinum sulfidation vs. peroxide sulfidation).
