Organic silicon material consists of silicone rubber, silicone oil and two processing products, silicone resin and silane coupling agent four categories of products. Because silicone products have radiation resistance, electrical insulation, flame retardant, corrosion resistance, high and low temperature resistance, morphological diversity and physiological inert and other excellent characteristics, known as "industrial monosodium glutamate", is widely used in electrical and electronic, textile, building materials, light industry, medical, transportation, machinery, plastics and rubber industries, and further to all areas of people's lives, to become a leader in the development of new chemical materials, it can be just unfolding. At present, the global annual production capacity of more than 1200000 tons, the product varieties are about 5000 - 10000 of the total market value of about $7000000000.

The main products and application of silicone

At present, many varieties and grades of silicone products, up to more than 10000 kinds of commonly used, there are more than 4000 species, can be roughly divided into raw materials, intermediates, products and three categories of products:

Organosilicon monomer: mainly refers to the single organic chlorosilane synthesis of organosilicon polymers, such as methyl chlorosilane, phenyl trichloro silicane, vinyl chloride silane as raw materials.

Silicone intermediates: mainly refers to the linear or ring siloxane oligomers, such as six methyl siloxane (MM two), eight methyl siloxane ring four (D4), two dimethyl cyclosiloxane (DMC) etc..

Silicone products and products: from the intermediate by polymerization, and add all kinds of inorganic fillers or modified additives for silicone products. The main (high temperature vulcanization silicone rubber and RTV silicone rubber, silicone oil) and two products, silicone resin and silane coupling agent four categories. Silicone rubber by molding, extrusion and vulcanization molding, the conductive cap sealing ring, such as buttons, eventually activities.

1, silicone monomer

2, silicone intermediate

3, the silicon rubber

(1), heat vulcanized silicone rubber (RTV)

(2) the room temperature vulcanized silicone rubber (LTV 'S) and addition reaction type silicone rubber (LSR)

Application of room temperature vulcanized silicone rubber silicone rubber composition by changing structure filler, additives and polymer, crosslinking, and choose a variety of catalytic system, can be made of many different varieties of performance. The room temperature vulcanized silicone rubber is easy to use, and can be prepared to meet the technical requirements of the wide variety of its production and use, to grow with each passing day, the room temperature vulcanized silicone rubber grade foreign sales of more than 300. It is no exaggeration to say, is it play in every industrial field.

Application Department

The use of the characteristics of the

Main application range

The construction industry

Aging, pigmentation, adhesion

Replace the asphalt road, used as a sealant joints; sealing curtain wall panels, high-rise buildings and inner wall joints; kitchen tiles around the void fill the bathtub, urinals and water, around the seal etc..

Electronics industry

Electrical, weather resistance, excellent adhesion mediated, may at any time to the emergency

Widely used as encapsulation, perfusion, bonding, dipping and coating materials.

Aviation and aerospace industry

Flame resistant, corrosion resistant, radiation resistant

For a spacecraft window, vacuum pump system and electronic equipment, sealing, coating, sealing oil resistant parts.

The automobile industry

Fatigue resistance, adhesion

As the forming sealing washer, the car windshield, window and door frames, lamps, the exhaust pipe and sealing adhesive is easily affected by water spray device.

Medical and health work

Liquid silicone rubber, physiological inert

Concealed glasses and artificial cornea, dental impression material, such as anti noise earplug.

Other aspects

Adhesive, simulation

Manufacture of mould of ancient relics replication, seal on conventional weapons.

4, silicone oil

(1) the classification of silicone oil, silicone oil is a kind of different viscosity, non-toxic, odorless, non corrosive liquid, silicone oil is not easy to burn. Among them, methyl silicone oil is the main varieties of silicone oil, the type of polymerization degree and organic radical change or polysiloxane, silicone and other organic copolymer can be prepared with silicone oil, waterproof, anti adhesive, release, defoaming and other basic characteristics. A lot of silicone oil variety, can be broadly divided into linear and modified silicone oil silicone oil two categories.

(2) silicone products and application of silicone oil has many special properties, such as small viscosity temperature coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non corrosive to metal, non-toxic and so on. Because of these characteristics, the application of silicone oil in many ways but with excellent results. In all kinds of silicone oil with methyl silicone oil, the most widely used, is the most important oil in varieties, followed by methyl phenyl silicone oil. A variety of functional silicone oil and silicone oil is mainly used for special purposes.
