Silicone Adjuvant Manufacturers introduced that siloxane has excellent physical properties and can be directly used in moisture-proof insulation, damping, shock absorption, defoaming, lubrication, polishing, etc. In addition to direct use, in order to disperse the methyl silicone oil well, it is convenient for dipping and spraying and improves efficiency. It can also be used in three types: solution type, lipid type, and emulsion type.
There are many types of polysiloxane, which are mainly divided into three categories according to the chemical structure and performance of the product:
①Silicone oil (modified silicone oil) is a low molecular weight (generally less than 10,000) linear structure polymer. In order to achieve certain properties, the molecular structure will also be grafted and modified. Colorless or light yellow transparent liquid, water-repellent, and oil-repellent, with high boiling point and low freezing point, good heat resistance, and chemical stability, used in various industries as chemical additives; the most common one can be used as Defoamer in various industries, hydraulic oil, high-grade lubricating oil, filler surface treatment agent and demulsifier, latex coagulant, also used as waterproof/water reducer for building materials, textiles, paper, and many other substances, plastics Lubricant and release agent in the industry, hair moisturizer in personal care, foam stabilizer in foaming polyurethane, leveling agent in the agricultural ink coating industry, etc., and also a good electrical insulator.
②Silicone rubber is a linear structure polymer with a large molecular weight (100,000 grade). After adding fillers and other additives and vulcanization, an elastomer, that is, silicone rubber can be obtained. Silicone rubber has the characteristics of electrical insulation, chemical stability, physiological inertness, and good elasticity in a wide temperature range; it is mainly used in the manufacture of rubber products used at high or low temperatures and artificial organs required in plastic surgery.
③Silicone resin is a linear structure polymer that contains active groups and can be further cured. It can be used to make heat-resistant high-grade electrical insulating varnish (silicon varnish), heat-resistant plastic (silicon plastic), laminated glass cloth and protective coating, etc.
