Silicone Polymers
Silicone is an inert synthetic compound that come in a variety of forms (oil, rubber, resin).
Basic Upstream Silicone Products
Chlorosilanes
The building blocks of silicones
Chlorosilane is chemical compounds prepared by reacting silicon powder and methyl chloride (CH3CI) gas through direct synthesis. The methyl chlorosilanes produced (trimethyl, dimethyl and methyl chlorosilane) are the building blocks for various silicone substances.

Silicone Oils
The ideal material for thermal stability
The most common silicone oils are linear polysiloxane compounds, that orient in spiral chains, which easily glide and slip over one another. Silicone oils offer great thermal stability and fexible and flowable forms at extreme temperatures. Polydimethylsiloxane is the predominant silicone polymer made, but other organic groups (phenyl, vinyl, epoxide or amino) can be added to the siloxane polymer that can in some cases offer special characteristics or reactivity.

Silicone Fluids
Silicone fluids are silicone oils (polydimethylsiloxane) which exhibit different degrees of polymerization, and thus viscosity.
Silicone Elastomers
Liquid Silicone Rubber
A Liquid silicone rubber is a high-purity, two-component platinum-cured silicone, ideally formulated for the production of technical parts, where strength, resistance and high quality are a must. LSRs are viscous, but pumpable materials, mostly processed through liquid injection molding (LIM)

Heat Cured Rubber
Heat Cured Rubber is a silicone elastomer formed of straight chains with very high molecular weight. The system will be cured with either an organic peroxide crosslinker, or a platinum catalyst. HCR offers great temperature and aging resistance.

RTV-1 silicone
RTV-1 is a one-component, Room Temperature Vulcanization silicone rubber that cures at room temperature. They are simple to use, apply and require no special preparation. RTV-1 silicones are ideal in critical applications where convenience and speed are prime requirements.

RTV-2 Silicones
RTV-2 silicones are two-component, Room Temperature Vulcanization silicone rubbers, gels or foams. Each part of the system comprises of either a crosslinker or a catalyst that will react when the two parts are mixed together to render the intended properties. It can be customized to produce variable degrees of viscosity, adherence and mechanical, chemical or temperature resistance characteristics.

Silicone Elastomers
Silicone elastomers are compounded using reactive, straight chained molecules together with a cross-linking agent and reinforcement.
Fluids
Silicone Resin
Silicone resins are relatively low molecular weight polymers with a three-dimensional branched-chain structure. With excellent thermal stability their many properties make them suited for use as binders in paints, varnishes and impregnating products.

Silicone Compounds
A silicone compound is made up of a hydrophobic particle (generally silica) dispersed in silicone oil, which produces a foam control or antifoam agent used in a great variety of applications.

Silicone Grease
Silicone grease is silicone oil based thickened with a lithium soap. Silicone Paste is silicone oil based with inert fillers. This type of grease and paste are waterproof and offers great fluidity and performances over a wide temperature range.

Silicone Emulsion
Silicone emulsions are silicone oils dispersed in an aqueous system. Emulsions are ideal for surface treatments, being easy to apply, and are simple to prepare.
