How does food grade silicone rubber pass the test

Hits: 520 img

Nowadays, silicone rubber products are more and more widely used in our daily life, such as: silicone rubber kitchenware, silicone rubber gloves/shoe covers, silicone rubber facial cleaners, silicone rubber fresh-keeping covers, silicone rubber seals and other products. As such products need to be in close contact with the human body, they must be produced with food grade silicone rubber raw materials and meet the corresponding food grade environmental protection testing requirements. At present, the mainstream food grade testing standards in the world include FDA, LFGB, ROHS, etc. Only after passing the corresponding testing standards can they be exported.

However, silicone rubber products are difficult to pass the test because some peroxides and other auxiliary materials are added during the molding process. If the silicone rubber product wants to pass the corresponding food level test report, first of all, we should choose the odorless vulcanizing agent or platinum vulcanizing agent in the production. After the silicone rubber products are vulcanized for the first time, they should be put into the oven for secondary vulcanization treatment, and then put the silicone rubber products into the boiling water for repeated boiling. After the chemical residues in the silicone rubber products are completely removed, they can basically pass the food level test.
