Elkem USA Corp products

Silicone is an inert synthetic compound that come in a variety of forms (oil, rubber, resin).

Depending on processing requirements or usage, silicone fluids may be used as 100 % materials, in a diluted form – mostly in halogenated hydrocarbons, aromatic compounds or high-boiling white spirit.

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

Silicone grease is silicone oil based thickened with a lithium soap.

Silicone elastomers are compounded using reactive, straight chained molecules together with a cross-linking agent and reinforcement to give good mechanical properties (elasticity, absorption, tear strength).

RTV-1 is a one-component, Room Temperature Vulcanization silicone rubber that cures at room temperature. 

RTV-2 silicones are two-component, Room Temperature Vulcanization silicone rubbers, gels or foams.

Heat Cured Rubber is a silicone elastomer formed of straight chains with very high molecular weight.

Liquid Silicone Rubber (LSR) is a two-component system, where long polysiloxane chains are reinforced with specially treated silica.
