Recently heard the most of a topic is that the choice of silicone material must choose food grade, so as to be safe, it seems that everyone is becoming more and more aware of this aspect, this is a good thing, but we do not know what is food grade, not all silicone is food grade silicone material.
Food grade silicone products products are inorganic polymer colloidal materials made of silicic acid condensation and a tube, the main ingredients are SiO2·nH2O, the content of which is more than 98%, has the characteristics of non-toxic, tasteless, stable chemical properties and so on, and under normal conditions in addition to caustic soda and hydrofluoric acid, not any acid base salt reaction.
First, the main characteristics of food-grade silicone products:
1. Non-toxic, odorless, high transparency, no yellowing;
2. Soft, elastic, kink resistance without deformation :(especially suitable for the baby to use without beating the heart accidentally broken and knock)
3. No cracking, long service life, cold and high temperature resistance;
4. With higher tear strength and superior electrical performance;
It has the advantages of high transparency, tasteless, unchanged yellow, no spray frost, especially to solve the problem of black hose spray frost, blue products fade, soft, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardant, anti-aging, environmental protection, tensile type, stable performance and other advantages.
Two, the performance of food-grade silicone products:
1, food grade silicone is a kind of environmental protection silicone, non-toxic, odorless, high transparency;
2, soft, good elasticity, kink resistance without deformation;
3, no cracking, long service life, cold and high temperature resistance;
4, with higher tear strength and superior electrical performance;
5, placed at room temperature unchanged yellow, no spray, no white, no fading, no scale in water for a long time, no odor;
Three, the main uses of food grade silicone products
At present, it is mainly used for dry household silicone products, candy mold, food cake mold, household appliances (keyboard silicone keys), silicone ice box, silicone pacifier, silicone bowl, silicone shovel, silicone fresh-keeping cover, silicone gloves, silicone heat insulation pad, etc.
