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

With the continuous penetration of silicone products in people's lives, more people are aware of the uses of silicone products. I believe that many people have heard of the ring silicone products are graded, one of them is food-grade silicone products, but what is food-grade silicone products in the end? What is the difference between food-grade silicone products and silicone products made of ordinary materials?

Food-grade silicone products are a kind of inorganic polymer colloid material made of silicic acid condensation, which is characterized by non-toxic, odorless, high transparency, no yellowing; soft, elastic, kink-resistant, no deformation, no cracking, long service life, cold and high temperature resistance, and higher tear strength and superior electrical properties.

In terms of application areas, ordinary silicone materials are commonly used in machinery, electronics, automobiles and some accessories in the agricultural industry, while food-grade silicone products can achieve a higher purity of environmental effects, as well as the improvement of various performance effects, so food-grade silicone products are more powerful and better texture. At present, they are mainly used for silicone products needed by families, candy molds, food cake molds, household appliances (keyboard silicone keys), silicone ice grids, silicone pacifiers, silicone bowls, silicone spatulas, silicone fresh covers, silicone gloves, silicone heat insulation mats, etc.

From the point of view of cost, the cost and price of ordinary silicone products are low, the quality of the product is medium, whitening phenomenon will occur when stretching, tearing effect is common, on the basis of ordinary glue, improved vapor phase adhesive, the higher the quality of raw materials, no whitening phenomenon, the longer the service life, the wider the application area, the higher the purity of raw material density, the price is also relatively expensive.

Through the above introduction, I believe that you have a certain understanding of food-grade silicone products. Of course, it is not to say that ordinary silicone products must be bad, ordinary silicone products also have their own field of application, according to the material applicable is the best, such as food-related products try to choose food-grade silicone products, if it is some other machinery, agricultural industry, no special requirements, you can choose ordinary silicone products to reduce costs.
