Liquid silica gel is a kind of highly active adsorption material and belongs to amorphous substance. Its chemical formula is mSiO2 nH2O. Liquid silicone products have high transparency and no odor. Product injection edge, no obvious pattern, burr defects, beautiful appearance. In addition, liquid silica gel is also in the molding process without adding any auxiliary materials such as vulcanizing agent.

The viscosity of liquid silica gel is generally related to the molecular weight of siloxane between them. Low molecular weight, low viscosity of monomer. Linear additions to viscosity exist, for example from 100cps to tens of thousands of CPS, which are also associated with inorganic fillers and hardeners. For example, even low viscosity silica gel can become very hard when the silica micropowder has a high solid content and solidifies. Various types of silica gel due to different manufacturing methods, also constitute different microporous structures. The chemical composition and physical structure of silica gel determines that it has many other similar types.

Compared with solid high temperature vulcanized silicone rubber, liquid silicone rubber can be divided into two categories: one is the far-claw type liquid rubber with functional groups at both ends of the molecular structure; The other is the active functional groups randomly distributed on the main chain, that is, the molecular structure of functional groups known as non-teleclaw liquid rubber.
