Polysiloxane type Jun 14, 2018

There are many kinds of polysiloxanes, which are mainly divided into three categories according to the chemical structure and properties of the products.

1.Silicone oil is a low-molecular-weight (typically less than 10,000) linear structure polymer that will also undergo graft modification of the molecular structure in order to achieve certain properties. Colorless or light yellow transparent liquid, hydrophobic oleoresin oil, high boiling point and low freezing point, good heat resistance and chemical stability, applied to all walks of life as chemical additives; the most common is Silicone,Silicone can be used as a defoamer in all walks of life, hydraulic oil, advanced lubricants, filler surface treatment agents and demulsifiers, latex accelerator, can also be used as waterproofing/reducing water for building materials, textiles, paper and many other materials. Agents, lubricants for the plastics industry, mold release agents, hair humectants for personal care, foam stabilizers for foaming polyurethanes, and agricultural ink coating industries can also be used as leveling agents, gold, etc., and are good electrical insulators at the same time .

2.Silicone rubber is a linear structural polymer with a large molecular weight (100,000). After adding fillers and other additives, vulcanization, available elastomer, that is, silicone rubber. Silicone rubber has the characteristics of electrical insulation, chemical stability, physiological inertness, and good elasticity over a wide range of temperatures; it is mainly used for the manufacture of rubber products that are used at high or low temperatures and artificial organs that are needed in plastic surgery.

3.Silicone resins are linear structural polymers that contain reactive groups that can be further cured. Can be made of high-grade heat-resistant electrical insulation paint (silicone paint), heat-resistant plastic (silicone plastic), laminated glass cloth and protective coating.
