In many stages of industrial production, there are always some "invisible heroes"—those that, though not directly present on the surface of the final product, can improve product quality and efficiency and optimize processes through their unique properties. Hydroxyl silicone oil is such a high-performance additive widely used in many fields. Its excellent comprehensive properties make it an indispensable core raw material in many industries.



From a basic property perspective, hydroxyl silicone oil is a colorless and transparent liquid, pure in appearance and free of impurities. It possesses multiple excellent properties, making it a versatile industrial additive. It has excellent electrical insulation properties, enabling it to function stably in complex circuit environments. At the same time, it has extremely strong resistance to high and low temperatures, maintaining stable performance within an extreme temperature range of -50℃ to 250℃, and will not fail due to drastic temperature changes.

Furthermore, hydroxyl silicone oil boasts a high flash point and low freezing point, ensuring greater safety during use. Its low viscosity-temperature coefficient means its viscosity is minimally affected by temperature, maintaining stable performance under various operating conditions. Its high compressibility and low surface tension contribute to its excellent wetting and diffusion properties, while also providing superior hydrophobicity and moisture resistance, effectively preventing moisture erosion. More importantly, it is both chemically and physiologically inert, will not react chemically with other substances, and is non-irritating, making it suitable for a wider range of applications.

The application value of hydroxyl silicone oil largely depends on the differences in its hydroxyl content and viscosity. Products with different parameters can be precisely matched to the needs of different industries, achieving a "tailor-made" application effect. In the paper industry, medium-to-high viscosity hydroxyl silicone oil is a high-quality anti-sticking agent base for paper. When applied to label backing paper, asphalt packaging paper, sealing paper backing paper, and decorative paper backing paper, it can form a dense anti-sticking film after curing, effectively preventing paper from sticking, ensuring paper flatness and user experience, while also improving the paper's weather resistance.

In the power and electrical appliance industry, the high insulation properties of hydroxyl silicone oil have been fully utilized, and it is often used as a major component of insulating varnishes or a core component of insulators. It can form a stable insulating layer on the surface of electrical equipment, effectively isolating current, preventing leakage, improving the insulation performance and service life of the equipment, and safeguarding power transmission and electrical operation. It is especially suitable for electrical equipment in complex working conditions such as high temperature and humidity.

In the field of silicone rubber processing, hydroxyl silicone oil is an indispensable core raw material. It can be used as a base rubber and diluent for condensation-type room temperature vulcanizing silicone rubber, and is widely used in the production of sealants and mold adhesives, which can optimize the molding performance and stability of silicone rubber. Among them, small molecule hydroxyl silicone oil (25-30 CP, hydroxyl content of about 8%) plays a special role and can be used as a structure control agent for silicone rubber.

Compared with traditional raw material diphenyl dihydroxysilane, small molecule hydroxy silicone oil can not only simplify the processing technology of silicone rubber, eliminate the cumbersome heat treatment process, greatly improve processing efficiency and reduce production costs, but also significantly increase the transparency of products, enabling silicone rubber products to achieve dual improvement in appearance and performance, while reducing cumbersome steps in the processing process and improving the production environment.

Furthermore, hydroxyl silicone oil can replace dimethyl silicone oil and has the advantage of easy emulsification, making it more convenient and flexible for use in industries such as daily chemicals and textiles that require emulsification systems. Whether it's optimizing product performance, simplifying production processes, reducing production costs, or increasing product added value, hydroxyl silicone oil can empower various industries with its unique comprehensive properties.
