Nowadays, silicone products are increasingly widely used in our daily lives, such as silicone kitchenware, silicone gloves and shoe covers, silicone cleansers, silicone fresh-keeping covers, silicone sealing rings, and so on. Due to the need for close contact with the human body, this type of product must be produced using food grade silicone raw materials and meet the corresponding food grade environmental testing requirements. Currently, the mainstream international food grade testing standards include,, etc. Only after passing the corresponding testing standards can it be exported for foreign trade.

Due to the addition of some peroxides and other auxiliary materials during the molding process, silicone products have certain difficulties in passing the testing. If silicone products want to pass the corresponding food grade testing report, first of all, we need to add vulcanizing agents during production. We should choose odorless vulcanizing agents or platinum vulcanizing agents. After the silicone product is vulcanized once, it needs to be placed in an oven for secondary vulcanization treatment. Then, the silicone product is repeatedly boiled in boiling water, and after the chemical residues inside the silicone product are completely removed, it can basically pass food grade testing.
