I. Demolding and Polishing in Manufacturing Industries

Demolding and polishing silicone oils, with their excellent lubricity and anti - stick properties, have become indispensable in the manufacturing of rubber, plastic, metal casting, and building materials. As a demolding agent, they significantly reduce friction between molds and products, enabling easier demolding, increasing production efficiency, and extending mold life. For example, in rubber product manufacturing, complex rubber parts can be easily demolded without damage thanks to silicone oil. In polishing, a small amount of silicone oil added to polishing agents brings remarkable results to cars, leather, and furniture. After polishing with silicone - oil - containing agents, these products have a good gloss that is durable and resistant to water washing and pollution, enhancing their appearance and service life.

II. Surface Treatment Applications

Surface - treatment silicone oils, with their outstanding water - repellent properties, are widely used to treat various materials. For fabrics, paper, glass, and building materials, silicone oil treatment improves their water - repellency, moisture - proofing, and softness. Treated ceramics are used in radio elements and electrical equipment to prevent insulation performance degradation in humid weather. Special papers like kraft paper and glassine, after silicone oil treatment, have good hydrophobicity, wear resistance, and anti - stick properties. Building materials such as asbestos and cement, when surface - treated with silicone oil, have increased wind - erosion resistance and hydrophobicity, and the workability and fluidity of mortar are also improved, allowing them to better cope with complex building environments and climate conditions.

III. Uses in Daily Chemicals

Silicone oil has a wide range of applications in daily chemicals. In skin - care products, its addition improves the wetting and spreading of cosmetics on the skin, providing moisturizing and protective effects. It forms a breathable protective film on the skin surface, preventing water loss and keeping the skin soft and hydrated. In lipstick, silicone oil improves the dispersion of pigments, enhancing extensibility and user - friendliness, making the lipstick apply more evenly and smoothly with a fuller color. In hair - care products, silicone oil addition significantly improves hair combability, making it smooth and soft. It fills the gaps in hair cuticles, reducing tangles and frizz, making hair easier to comb and style in daily life, and helping to maintain hair health.

IV. Key Support for the Electronic and Electrical Industry

Electronic and electrical silicone oils, with their excellent high - and low - temperature resistance, good viscosity - temperature properties, and dielectric properties, are excellent electrical insulating materials. Compared with traditional oil - filled transformers, silicone - oil - filled transformers have the advantages of small size, high power, long life, and good electrical insulation. When used as electrical oil, silicone oil can replace polychlorinated biphenyls, reducing energy consumption, increasing working temperature, and improving safety. It plays a key role in the stable operation and energy saving of electronic and electrical equipment, ensuring good performance in various complex working environments and meeting the requirements of modern society for environmental protection and safety, promoting the sustainable development of the electronic and electrical industry.

V. Special Operation Assistance in the Mechanical Industry

Although silicone oil's lubricity is not as good as that of general mineral oils, its high - and low - temperature resistance is more outstanding. This enables it to be used in mechanical operation and bearings under high - and low - temperature conditions, ensuring the normal operation of mechanical equipment in extreme temperature environments. In addition, silicone oil has high compressibility, a small viscosity - temperature coefficient, and is less affected by temperature, so it can be used as shock - absorbing oil for various instruments and meters. It can effectively absorb and buffer vibrations, protecting the precision parts of instruments and meters and ensuring the accuracy of measurement and control. With good thermal oxidation stability, low vapor pressure, and low freezing point, silicone oil can be used as high - vacuum diffusion pump oil. Its excellent high - and low - temperature performance, as well as high radiation resistance and oxidation resistance, make it irreplaceable in some special fields and high - end equipment of the mechanical industry, providing strong support for the technological progress and equipment upgrading of the mechanical industry. By modifying the side chains and ends of silicone oil with different groups, a variety of properties can be achieved, thus expanding its application range in various downstream fields. Different modifiers and modification methods endow silicone oil with different characteristics, making it play an increasingly important role in modern industry and daily life and becoming an indispensable important material in many industries.
