Organosilicon Materials
Organosilicon materials are divided into four categories, namely silicone rubber, silicone oil, silicon resin and silane coupling agent. Since silicone products have good electric insulation resistance and are radiation resistant, flame retardant, corrosion resistant, high and low temperature resistant, they are known as the 'Industrial monosodium glutamate' and are used in the fields of electric products, building materials, textiles, medical treatment, machinery, transportation, plastics, etc. Presently, the world's annual production capacity of silicone products is about 1.2 million tons and there exists 5,000-10,000 different varieties. The total market sale is approximately 70 billion US dollars.

At present, there are more than 10,000 kinds of silicone products, of which 4,000 kinds are commonly used. Silicon products are generally divided into three groups, i.e. organosilicon monomer, organosilicon intermediates and organosilicon products.
Organosilicon monomer: Refers to the monomer synthesis of organochlorines silane and silicone polymers, such as methyl chlorine silane, phenyl chlorine silane, vinyl chloride silane materials, etc.
Organosilicon intermediates: Refers to linear or ring-shaped siloxane oligomer, such as hexamethyldisiloxane (MM), octamethylcyclotetrasiloxane (D4), dimethylchlorosilane (DMC), etc.
Organosilicon products: Obtained by polymerizing the intermediates and adding various inorganic fillers or modified additives. Examples of this category are silicone rubber, silicone oil, silicon resin and silane coupling agent. By means of extrusion or compression molding, silicone rubbers can be processed to become conductive buttons, sealing rings, swim caps and many useful products.

Silicone Rubber
Hot Vulcanization Silicone Rubber

The hot silicone rubber can be processed into various products just like other rubbers. For instance, it can be molded into rubber tubes, rubber strips, rubber rollers, and rubber tapes. The key feature of the hot vulcanization silicone rubber is its biocompatibility. Note that this material does not have actual use value without reinforcing it.

Room Temperature Vulcanization Silicone Rubber (RTV)
The RTV silicone rubber requires silica reinforcing agent, otherwise its intensity is even lower than hot vulcanization silicone rubber. By using different filler materials, additives, cross-linking agents, and catalyzing systems, this silicone rubber can be used to make numerous kinds of products. It is used in hundreds of industrial fields, including electric industries, construction industries, textiles, machinery, etc.

RTV Rubber Application
Application Field Property Main Application Range
Construction Industry Anti-ageing property, coloring, good adhesiveness It can replace asphalt to serve as highway seam sealants; curtain wall and inner wall sealing for high building; sealing of ceramic tiles, basins, etc.
Electronic Industry Good dielectric property, weather resistance, adhesiveness Encapsulation, pour molding, dipping, adhesive bonding, etc.
Aviation and Aerospace Industry Flame retardant, corrosion resistance, radiation resistance. Used as sealant for spacecraft windows, vacuum air pump systems, electronic devices, oil resistance parts; ablation coating.
Automobile Industry Fatigue durable, good adhesiveness To seal automobile windows, door frames, reflector lamp, exhaust pipes, etc.
Medical and Health Liquid silicone rubber, physical inertia Contact lenses, artificial corneas, dental stamping materials, earplugs.
Others Adhesiveness, good simulation Used to make molds for antiquity replication and conventional weapon sealing.

Silicone Oil
Silicone oil is a non-toxic, odorless, corrosion resistant, nonflammable polisiloxane oily substance. Different silicone oil comes with different viscosities. By altering the polymerization degree and the type of organic group, various useful properties can be added to silicone oil, such as water resistance, adhesive resistance, de-foaming, etc. Silicone oil can be roughly divided into linear silicone oil and modified silicone oil. The main properties of silicone oil are extreme temperature resistance, antioxidant, low volatility, good insulation resistance, good surface tension, non-toxic, etc. Silicone oils are primarily used as lubricants or hydraulic fluids, and working fluid in diffusion pumps, etc.

Silicone Oil Application
Application Field Property Main Application Range
Machinery Industry High temperature resistant, antioxidant, strong shear resistance Lubricants for transmission devices, shockproof damping oil, vacuum oil diffusion pump.
Electrical appliance Industry Dielectric property, heat resistant, hydrophobic property Providing insulation, heat resistant, etc. for transformers, capacitors, transistors, etc.
Chemical Industry Low surface tension, good chemical stability De-foaming agent for chemical processing steps such as fermentation, papermaking, fabric dyeing.
Medical Non-toxic, hydrophobic property, surface activity De-foaming agent, additives, lubricants for artificial eyeball, disinfectant, etc.
Common Industry Adhesive resistance, weather resistance Serve as paints, rubbers, plastic additives, demolding agent, etc.
Common Industry Anti-corrosion, hydrophobic property Surface processing for glasses, ceramics, paper, leather, metal, textiles, etc.
Silicon Resin Application
Product Type Application Range
Insulation Paint Coil varnish for electrical equipment; binding material for mica; insulation paint for glass silk, fiberglass, asbestos cloth, etc.
Paint Heat resistant and weather resistant paint, scratch resistant transparent paint, de-foaming paint, radiation resistant paint, damp proof paint, etc.
Adhesives Binding material between metals and heat resistant non-metal materials, binding material for heat resistant rubbers and metals, adhesives for binding insulation material with steel or titanium alloy, etc.
Organosilicon Plastics Mold pressing plastics for semiconductor encapsulation, laminated plastics, foam plastics, etc.

Silane Coupling Agent
Silane was first developed as a fiberglass reinforcing agent since it can strengthen the bonding between fiberglass and resins. Today silane is used as coupling agents to adhere fiberglass to polymer matrix, stabilizing the composite material. Silane coupling agent is static resistant, moldproof, anti-odor and anti-clotting, etc. and can be used for surface treatment.

Silane Coupling Agent Application
Application Field Application Effect
Fiberglass Reinforcement Effectively improve the wet state machinery properties and stabilize the electric properties.
Filler Materials for Mineral Powder Enhance the machinery intensity of composite materials, optimize processing property, improve the wet-ability and dispensability of filler materials.
Tackifier Used as tackifier for general sealants and adhesives such as epoxy, polyurethane, chloroprene rubber, etc.
Rubber Processing Enhance the dispensability of inorganic filler materials in rubber, improve the physical electric property and overall processing property of rubbers.
Others Used for glass surface treatment to prevent glass from freezing
