Silicone oil is usually a linear polysiloxane product that remains liquid at room temperature. It is generally a 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 usually called silicone oil.It is usually not simply used, but made through special formulations, and is often used as an auxiliary material to produce a certain effect.Generally speaking, there are three basic forms of silicone oil on the market: pure silicone oil, solution, and emulsion. 

    1, pure silicone oil has very strong stability

    Heat resistance, frost resistance, good storage, with high flash point and high ignition point, storage and transportation problems are few.

    2, in fact, often need to dilute the silicone oil solution

    Sometimes want to add active auxiliary agents in the solution (catalyst, crosslinking agent, etc.) for storage and use, according to the need can be used aliphatic, aromatic or chlorinated hydrocarbons as solvents, special cases to use other kinds of solvents, general polymer polysiloxane solution, concentration can only reach 35%, otherwise the viscosity is too large.

    3, a large part of the silicone oil or silicone oil containing products are made into emulsion form

    Compared with solvent silicone oil, it has the advantages of cheap, not easy to burn, harmless to health and so on.Different from the solvent type, all silicone emulsions are "oil in water" type heterogeneous system, its external closed phase is the aqueous phase, silicone oil dispersed in the aqueous phase with very small drops, it is easy to dilute with water to the required concentration for application, the stability of this emulsion can be achieved by making the droplets as fine as possible and the stabilization effect of the emulsifier.

    Different forms of silicone oil have their own unique characteristics, pure silicone oil is the simplest form, convenient transportation and storage.And silicone oil solution and silicone oil emulsion convenience will be less, in short, each has its own good, we can choose according to the needs.
