    There are many reasons for unqualified silicone products in the production process, especially the hygiene of food-grade silicone, which is mainly reflected in the production of silicone kitchenware.Below, Xinjia will give you an analysis of the reasons leading to the unqualified food grade silicone products.


    Some silica gel factories pay attention to the raw materials used in kitchenware. Without testing the raw materials, they use silica gel with low quality grade for the production of food tools, or use unqualified color glue and additives for coloring in the production process, resulting in unqualified product hygiene.It is mainly manifested in the following aspects:


    1. The production process is not standard. Due to the particularity of the safety requirements of silica gel tableware, the production process of food silica gel products is very strict, and the products need enough time to remove volatile substances after molding.In order to pursue efficiency, some factories do not have enough processing time for their products.


    Two: the secondary vulcanization of silica gel products, secondary vulcanization is also called after vulcanization.The role of secondary vulcanization: when silicone rubber is vulcanized by peroxides, the decomposition of peroxides leads to the reaction of polymers, resulting in low molecular compounds (such as benzene and benzoic acid, etc.) that exist in rubber will affect the mechanical properties of rubber.


    Three: From the appearance, some silicone products break with a pull of the hand, no elasticity.If the mixed rubber at a certain temperature at a certain temperature vulcanization molding can be obtained products, like we usually see silicone spatula, silicone spoon, silicone steamer, as long as the poison is not toxic as long as the silicone manufacturers can provide food certification, generally speaking, are non-toxic. 


    So the overall effect food-grade silicone product unqualified outside the production technology and process, also is the food grade silica gel raw material choice, choose good quality food grade silicone materials can reduce a lot of problems, so I'd recommend new food grade silica gel, new of food grade silica gel is not restricted by the thickness of the products, deep sulfide, The raw material has been certified by FDA and EU ROHS as non-toxic and odorless, safe and environmentally friendly, and the product performance can be specially adjusted according to the requirements of production, welcome your consultation and understanding.
