Are GoSili products free from harmful substances like PFAS, formaldehyde, and BPA?Updated 2 days ago

Yes. Our products are made from premium platinum-cured silicone, which is the highest purity grade of food-safe silicone available. They are free from PFAS (per- and polyfluoroalkyl substances), formaldehyde, formaldehyde-releasing substances, BPA, BPS, phthalates, lead, and other harmful chemicals.

Platinum-cured silicone differs from lower-cost peroxide-cured silicone in important ways. The platinum vulcanization process uses platinum catalysts to create cross-linking at the molecular level, which produces a stable, inert material with no volatile byproducts. This is why our products have no chemical odor or taste transfer, and why they remain safe through years of daily use with hot and cold liquids.

Our manufacturing process follows three rigorous stages: compound preparation with precisely measured raw materials, platinum vulcanization under controlled temperature and pressure, and quality control inspection for every product. Each stage is designed to ensure consistent safety and performance.

Our products comply with FDA 21 CFR 177.2600 requirements for food-contact materials and undergo independent laboratory testing for migration, material composition, and food-contact safety. Third-party testing documentation and certification reports are available upon request to [email protected].
