Organosilicon, it is also called organosilicon compound. Organosilicone compound is what is composed by Si-C bonds and at least one organic group is directly connected to the silicon atom.Usually, those organic groups like oxygen, nitrogen, sulfur, etc, connecting to the silicon atom are also called silicone compound. Among all of them, polysiloxanes composed by silicon-oxygen bonds (-Si-O-Si-) are the most popular types. They are the most widely applied and researched type among all organosilicon compounds, which accounts for more than 90%. As per different forms, silicone materials can be grouped into: biologically active silicone, silane coupling agent (organosilicon chemical reagent), silicone oil (silicone emulsion, silicone surfactant, silicone grease), liquid silicone rubber,high-temperature vulcanized silicone rubber, silicone resin, etc. Silicone compounds have both properties of organic materials and inorganic materials. They have excellent performance such as:low and high temperature resistance, radiation resistance,oxidation resistance, flame resistance, good dielectric properties, hydrophobic, mold release,and low temperature viscosity coefficient. Silicone compounds are also tasteless, non-toxic, tasteless and physiological inertia. With these properties, silicone products are widely applied in different industries, such as:construction, electrical and electronic, chemical, light industry, medical, personal care, textile, agrochemical industry and other industries. Along with the continuous increase of organic silicon products varieties, the application fields are also expanding. Silicone compounds has formed an important and unique product line in the field of new chemical materials. Many silicone varieties are irreplaceable and indispensable by other chemicals. With its wide application and development prospects in the forefront of science and technology, it is also known as technological catalysts and industrial vitamins. There are different types of organic silicone products. Its varieties and brands are over 10,000, and around 4,000 of them are commonly used. In 2018, the polysiloxane consumption in China was about 1.044 million tons. Silicone rubber accounted for 66.90% of the total consumption, silicone oil accounted for 29.50%, and silicone resin and others accounted for 3.60%. From the downstream part, the largest consumption is in industries like construction, electricity and new energy, electronic appliances, personal care and. It is expected that in the next 5 years, the main application of silicone materials will still among industries like construction, textiles, electronics, textiles, medical treatment and personal care;Photovoltaic, 3D printing, smart werable device and other new market will be the breakthrough point and market increase point for silicone materials.
