How much is the mold silica gel hardness appropriate?

   Mold silica gel, as the name suggests, is used to make mold with silica gel raw materials, mold silica gel according to different types into condensed mold silica gel and molding mold silica gel. Condensed mold silica gel is industrial grade mold silica gel, which is not environmentally friendly material. Because its curing agent is organic tin curing agent, it is also called organic tin industrial silica gel. Molding mold silica gel is food grade liquid silica gel, which belongs to environmental protection materials, divided into two components, AB group B is divided into platinum catalyst, so it is also called platinum environmental protection silica gel.
   Whether industrial grade silica gel or food grade silica gel, there are a lot of hardness, from 0 degrees to 50 degrees of high and low ranking, every 5 degrees in the middle of a unit. Mold silica gel under different hardness, their tear strength, elongation and tensile strength are not the same, customers can choose the appropriate hardness according to their own products. So the most widely used mold silica gel hardness is how much degree, mold silica gel hardness how much is appropriate?
   Among many different hardness silica gel, 25 degrees of hardness of the mold silica gel is the most widely used. 25 degrees of hardness is a representative of medium hardness, which can be applied to the production of many products, such as 25 degrees of industrial grade mold silica gel, which is widely used in the production of cement block carving, cultural stone and other molds. 25 degrees of mold silicone tear resistance and tensile strength is a strong performance. In addition to the molding mold silica gel liquid silica gel, 25 degree mold silica gel can be used to make a variety of food silicone mold, environmental protection, non-toxic and tasteless, and simple operation.
There are many application fields of customers, and each application has silica gel with appropriate hardness. In principle, silica gel with appropriate hardness is recommended according to the size of customers' products.
