What is the difference between food grade silicone and ordinary silicone?

With the continuous penetration of silicone products in our life, let more people understand the use of silicone products. I believe that many people have heard that there is a classification of ring silicone products, one of which is food grade silicone products, but what is food grade silicone products? What are the differences with ordinary silica gel?

Food grade silicone products is a kind of abbreviation of inorganic polymer colloidal materials made of silicic acid condensation, which is characterized by: non-toxic, odorless, high transparency, no yellowing; Soft, good elasticity, kink resistance, no deformation, no cracking, long service life, cold and high temperature resistance, and has higher tear strength and superior electrical properties.

From the application field, ordinary silicone material is often used in machinery, electronics, automobile and some accessories in the agricultural and industrial industries, and food grade silicone products can achieve higher purity of environmental protection effect, as well as various aspects of performance effect improvement, so the role of food grade silica gel products is more powerful, texture is better. At present, it is mainly used for silicone products, candy mold, food cake mold, household appliances (silicone keyboard cover), silicone bottle stopper, silicone pacifier, silicone bowl, silicone spatula, , silicone placemat, silicone heat insulation pad and so on.

From the point of view of cost, the cost of ordinary silica gel products and low price, product quality is medium, tensile whitening phenomenon would appear, tear general effect, on the basis of ordinary glue, the gas phase adhesive is improved and the higher the quality of raw materials, without bleaching, longer service life and application field is wider, material density, the higher the purity, the price is relatively expensive.
