Silicone oil usually refers to the linear polysiloxane product that keeps liquid state at room temperature. It is generally colorless (or light yellow), tasteless, non-toxic and non-volatile liquid. Their molecular weight is not high, at room temperature for the flow state, so it is usually called silicone oil. It is not only used, but also made by special formula. It is often used as auxiliary material to produce a certain effect.










Generally speaking, there are 3 basic forms of silicone oil in the market: pure silicone oil, solution and emulsion.










1. Pure silicone oil has very strong stability








Heat resistant, frost resistant, good storage, high flash point and high ignition point, few storage and transportation problems.










2. In fact, it is often necessary to dilute the silicone oil solution








Sometimes it is desirable to add active auxiliary agents (catalyst, cross-linking agent, etc.) to the solution to facilitate storage and use. Aliphatic, aromatic or chlorinated hydrocarbons can be used as solvents as required. In special cases, other kinds of solvents are used. Generally, the concentration of high molecular polysiloxane solution is only 35%, otherwise the viscosity is too high.










3. a large portion of silicone oil or silicone oil is made into emulsion form.








Compared with solvent silicone oil, it has the advantages of low price, not easy to burn and harmless to health. Different from the solvent type, all silicone emulsions are "oil in water" heterogeneous systems. The external sealing phase is water phase, and silicone oil is dispersed in water in very small drops. It is easy to dilute the water to the desired concentration for application. The stability of the emulsion can be achieved by minimizing the droplet size and stabilizing the emulsifier.
