Silicone oil, as a multifunctional lubricant, is widely used in mold release, anti-adhesion, and smoothing treatments. In industries such as rubber, plastics, metal casting, glass, paper, and fiber production, silicone oil has a long history of use. And with the development of technology, its application range and usage continue to expand.
Classification and characteristics of silicone oil:
High-viscosity silicone oil: Provides excellent mold release and anti-adhesion properties while maintaining a smooth surface treatment.
Low-viscosity silicone oil: Has excellent coating properties and surface affinity, suitable for fine coating applications.
Typical applications of silicone oil:
Dimethyl silicone oil: A commonly used silicone oil. Its viscosity range is usually between 0.1 and 30 Pa·s, which can balance mold release and coating performance.
Methylphenyl silicone oil: In some specific applications, such as fiber production, it is favored for its thermal stability and low viscosity-temperature coefficient.
Formulation and use of silicone oil:
Silicone oil can not only be used alone but also be formulated into solutions, emulsions, aerosols, or greases to meet different industrial needs.
Application of silicone oil in the textile industry:
Oil agents for fiber precursor filaments and raw cotton: Low-viscosity dimethyl silicone oil is widely used as an oil agent due to its temperature resistance and non-discoloration characteristics.
Spinning oil agents: Combined with antistatic agents, emulsifiers, etc., oil agents formulated with dimethyl silicone oil and methylphenyl silicone oil are used in the spinning process of synthetic fibers such as nylon, polyester, and spandex to effectively prevent broken filaments and loosening.
Application of silicone oil in metal casting:
Mold release treatment: In the melt spinning process, dimethyl silicone oil is used for mold release treatment of nozzles to prevent the adhesion of carbides or melts, thereby avoiding broken filaments.
