Is food grade silicone graded

Food grade silicone is classified into different grades due to differences in material formulas and production processes, as well as differences in the selected raw materials and production costs. For example, although food grade silicone used for mold making meets food grade standards, its flexibility, tear resistance, shrinkage rate, aging resistance, oil resistance, and mold turning life may vary. These differences are often related to the quality of the added raw materials. When consumers purchase food grade silicone, they should choose based on their own production needs and the concept of product quality requirements, rather than just considering price factors.
