What is Silicone Material？What are the classifications?

Silicone materials are mainly oligo- or polymers with polysiloxane-containing main chains. Such compounds are often referred to as Silicone in English. The word Silicone is formed from the beginning of the word in (Silic) and the end of the word ketone (-one).

The word was first coined in 1857 by the German chemist F. Wohler, but it was F. S. Kipping who used it to describe polydiphenylsiloxane, the product of the hydrolysis and condensation of dichlorodiphenylsilane, and who also knew at the time that polydiphenylsiloxane was a high-molecular-weight compound and diphenyl ketone was a small molecule, and who pointed out their completely different chemical properties. Kipping also knew at the time that polydiphenylsiloxanes were high molecular weight compounds and diphenyl ketones were small molecules, and also pointed out their completely different chemical properties.

Although it has long been recognized that silicon is more likely to form two single bonds with two oxygen atoms than a silicon oxygen double bond due to the larger covalent radius of silicon, Silicone is still commonly used to define polymerized silicone products, and generally refers to complex and often undefinable products in precise scientific terms, which are usually mixtures of many components.

In terms of product form, silicone materials can be classified as silicone oil or silicone fluid (including silicone grease, silicone emulsion, silicone surfactant, etc.), silicone rubber (including room temperature vulcanized and high temperature vulcanized silicone rubber), silicone resin, and silane coupling agent (coupling agent, coupling agent, etc.). Silicone rubber (including room temperature vulcanization and high temperature vulcanization silicone rubber), silicone resin and silane coupling agent.

Silicone Oil

Silicone oil and silicone oil products is an important class of silicone materials, it has many varieties, can be divided into ordinary silicone oil and modified silicone oil two categories. Modified silicone oil in the polyether modified accounted for the vast majority, followed by chlorine modified, epoxy modified, alkyl modified, hydroxyl modified, mercapto modified, alcohol modified silicone oil and so on. Silicone oil products are mainly defoamers, release agents, paper isolators, fabric finishing agents and silicone grease. Silicone resin has lubrication, electric insulation, anti-fouling flash and thermal conductivity and other series of products. The main demand industries are machinery industry, electronic power industry, chemical industry, textile dyeing and finishing industry, paper products, medicine and cosmetics industry.

Silicone Rubber

Silicone rubber is the silicone products in the largest production, the most varieties of brands of a class. According to the structure of the raw rubber silicone rubber can be divided into methyl silicone rubber, methyl vinyl silicone rubber, phenyl silicone rubber, cyano-silicone rubber and fluoro-silicone rubber. According to its vulcanization temperature, silicone rubber is divided into high-temperature-vulcanized, HTV and room-temperature-vulcanized, RTV two kinds. Room-temperature vulcanized silicone rubber generally consists of two categories: condensed and molded. The three major industries in demand for silicone rubber are construction, electrical and electronics, and automotive.

Silicone Resin

Silicone resin is one of the main large categories of silicone products. Although it is the earliest of the silicone materials introduced, but its varieties are relatively small, the market share is also small. The main use is to formulate a variety of electrical insulation paint, weather-resistant coating, plastic surface wear-resistant coatings and high temperature coatings. In addition, it is also used as mica adhesive, asbestos cloth glass cloth impregnation paint, mud gel and masonry waterproofing agent. It is widely used in aerospace, electronics and electrical appliances, construction, machinery manufacturing and so on.

Silane Coupling Agent

Silane coupling agent is essentially a class of organic functional groups of silicon burns, in its molecule at the same time and inorganic materials can be chemically bonded to the reaction group and organic materials compatible or can be chemically bonded to the group. It was first used in the surface treatment of glass fibers in glass fiber reinforced plastics. Now it is used to improve the performance of various polymer composites, and its use is increasing year by year.
