The organic compound of silicon combines the excellent inorganic properties of silicon with the properties of organic materials, making the organic silicon compound unique and opening up new areas. It has the basic properties of low surface tension, low viscosity-temperature coefficient, high compressibility, high gas permeability, etc., and has high and low temperature resistance, electrical insulation, oxidation stability, weather resistance, flame retardancy, hydrophobic Toxic, odorless, and physiologically inert, and other excellent characteristics, mainly used in sealing, bonding, lubrication, coating, surface activity, demoulding, defoaming, foam suppression, waterproof, moisture-proof, inert filling, etc. With the continuous growth of the number and variety of silicones and the continuous expansion of application areas, silicones have become a unique and important product system in the field of new chemical materials. Many silicones are irreplaceable and indispensable for other chemicals.
According to their different forms, silicone materials can be divided into: silane coupling agent (organosilicon chemical reagent), high temperature vulcanized silicone rubber, liquid silicone rubber, silicone oil (silicone grease, silicone emulsion, silicone surfactant), silicone resin, composite Things etc. For example, organic plastics can be made into waterproof fabrics with excellent performance. Silicone sprayed on the four walls of the subway can solve the problem of water seepage. The surface coatings of ancient cultural relics and sculptures are also organic silicon compounds. Silicone oil can be made into a good lubricant. Silicone rubber can be used as an insulating material as well as a medical polymer material. Affected by the distribution and demand of my country's textile, electronics, medical, daily chemical and other terminal industries, silicone rubber occupies half of the downstream products of organic silicon.
