POWERSIL® silicone rubber grades and POWERSIL® insulator coatings are 1- and 2-pack silicone compounds. The rubbers cure at either ambient or elevated temperature in accordance with how they are processed. Conventional methods are employed for this, i.e. spraying (silicone coatings), compression molding, injection molding, low-pressure mold filling (LPMF), and extrusion. The products are used for making:
- Insulators
- Surge arresters and bushings
- Coupling sleeves, cable terminals and connectors
POWERSIL® products are supplied in different classes that offer a full range of properties for all kinds of applications:
HTV
- Broad product range for various processing technologies, such as injection molding and extrusion
- Outstanding electrical insulation is a basic property. Several grades have been modified to provide electrical conductivity
- Huge selection of modification options with regard to curing process, color and other properties
LSR
- Comprehensive product portfolio, e.g. including electrically conducting grades
- Exceptional mechanical properties
- High potential for new developments and modifications
RTV-1 (especially coatings)
- Hydrophobic coatings, with transfer of hydrophobic properties to adjacent layers of grime
- Adhesion to most common substrates
RTV-2 (especially cable accessories)
- Good electrical properties
- Good mechanical properties
- Simple production technology
