One- and two-part RTV silicone rubbers resemble gels in that they are made up of low molecular-weight polymers. As a result, these silicone rubbers generally have good flow properties without external pressure. However, individual grades are modified for the particular application, for example as pastes and/or shear-thinning grades. Depending on the viscosity and the specific rheological properties, these materials are dispensed or sprayed via metering systems at low pressure. Manual processing is also possible.
Liquid silicone rubbers are processed by injection molding. However, these materials only become really liquid under shear, at the high pressure during mold filling. When stationary, they are usually paste-like liquids with a consistency like honey. Liquid silicone rubber is always addition-curing (platinum-catalyzed).
Solid silicone rubber contains polymers with a high molecular weight and relatively long polymer chains. It is referred to as HTV (= high-temperature-vulcanizing). We offer you solid silicone rubber in two product lines: peroxide-curing grades and addition-curing (platinum-catalyzed) grades. The standard form of supply of solid silicone rubber is in block form. In the ready-to-use compounds, the material is also supplied in the form of strips, cord, pellets and profile strips.
