Now the application of mold silicone in the market is more and more extensive, customers also have a lot of choices, you can choose the right mold silicone material for your own products according to different product needs; At present, mold silica gel is mainly divided into two kinds, one is molding food-grade mold silica gel, and the other is condensed industrial-grade mold silica gel; Food grade mold silica gel is a platinum system of silica gel raw materials, environmental protection, non-toxic and tasteless, can be used to make food molds or adult products and other fields; Condensed industrial grade silica gel is mainly used for cultural stone, resin crafts and other products, so how to distinguish food grade silica gel and industrial grade silica gel mold?

1, smell: at present, there are two kinds of mold silicone in the industry, molding food-grade silicone and condensed industrial silicone, molding silicone is non-toxic and tasteless; Condensed silica gel is also called industrial grade silica gel, which is not environmentally friendly and has a toxic odor. Food mold silica gel is added molding environmental protection grade silica gel, is non-toxic and tasteless, therefore, we can distinguish through smell, smell must not be food grade.

2, look at the mixing ratio: the mixing ratio of food-grade mold silicone is 1:1 or 10:1, and the mixing ratio of industrial grade silicone is 100:2 or 100:4.

3, touch feel: the toughness and elasticity of food mold silicone are very good, it is not easy to permanently deform due to external force, and the feel will feel relatively smooth, while industrial silicone products are easy to deform, and it is relatively rough to touch.
