Silicone oil, as a versatile lubricant, is widely used in demoulding, anti-sticking and smoothing. Silicone oil has a long history of use in industries such as rubber, plastics, metal casting, glass, paper and fiber production, and its application scope and dosage continue to expand with the development of technology.



Classification and characteristics of silicone oil High viscosity silicone oil: provides excellent demoulding and anti-sticking properties while maintaining smooth surface treatment. Low viscosity silicone oil: has excellent coating and surface affinity, suitable for fine coating applications.

Typical applications of silicone oil Dimethyl silicone oil: a commonly used silicone oil with a viscosity range of 0.1 to 30 Pa·s, which can balance demoulding and coating performance. Methylphenyl silicone oil: in certain specific applications, such as fiber production, it is favored due to its thermal stability and low viscosity-temperature coefficient.

Formulation and use of silicone oil Silicone oil can be used not only alone, but also in the form of solution, emulsion, aerosol or grease to meet different industrial needs.

Application of silicone oil in the textile industry Oil for fiber raw silk and raw cotton: Low-viscosity dimethyl silicone oil is widely used as an oil because of its temperature resistance and non-discoloration characteristics. Oil for spinning: Oil prepared by dimethyl silicone oil and methylphenyl silicone oil in combination with antistatic agents, emulsifiers, etc., is used in the spinning process of synthetic fibers such as nylon, polyester, and spandex to effectively prevent broken wires and looseness.

Application of silicone oil in metal casting Demolding treatment: In the melt spinning process, dimethyl silicone oil is used for the demolding treatment of the nozzle to prevent carbide or melt from adhering, thereby avoiding broken wires.
