Liquid silica gel is a kind of amorphous substance with high activity adsorption data, the chemical formula is mSiO2·nH2O, liquid silica gel products with high transparency and no odor, no obvious mold and hair edge shortcomings, delicate and beautiful appearance, liquid silica gel in the molding process, do not add any curing agent and other auxiliary materials.

    Silicone liquid viscosity are general and siloxane molecular weight, molecular weight, the lower monomer, the lower the viscosity, molecular weight, the higher the present linear adding viscosity for example from 100 CPS to tens of thousands of tens of CPS have, this also has relationship with inorganic fillers and curing agents, chemical components and physical structure of the silica gel, resolution to it has many other similar characteristics of the data will be hard to replace.Silica powder for high solid content after curing, even if it is low viscosity silicone will become very hard, various types of silica gel, also because it make way, constitute different microporous structure, liquid silicone pad printing silicone purposes, it is close to 50 degrees hardness sticky, raw material is relatively thick, molecular weight is more closely together, there is no liquidity, As for the rubber head, the product is relatively hard. It is necessary to adjust the viscosity of diluted silica gel through silicone oil to achieve the required liquidity to complete the hardness of pad printing rubber head. 

    Food grade mold silica gel is hardness, the more viscous silica gel its hardness is higher, the thinner the viscosity, the better the fluidity of silica gel hardness is lower!Therefore, we can adjust the viscosity, hardness and color according to the customer's product requirements.The raw material has good high temperature resistance, food grade, non-toxic, tasteless, and has passed FDA food grade certification.

    Silk screen silica gel raw material is also relatively thick, used for one-time molding of non-slip point plastic processing, for fast thickness, silica gel three-dimensional sense, strong adhesion.If you do the printing pattern trademark operation, you can adjust the fluidity through the release of dilute agent, which is used to enhance the brightness of the cover, better highlight the vividness and flexibility of the pattern, so that the effect is more natural and beautiful.

    The higher the viscosity, the higher the cross-linked molecular weight, the tighter it is, and the higher the hardness.Viscosity liquid silicone raw materials according to different products have different advantages, so in the operation of different products, to choose appropriate silicone raw materials, to the operation of different products, for different hardness, when the choice can communicate with suppliers according to the actual product, can better regulate the suitable raw materials for a targeted silicone products!
