Silicone Rubber

Silicone rubbers differ from other elastomers in their wide and unique property range. These properties result from their special chemical structure, consisting of an inorganic backbone with organic groups.

Our silicone HCR (high-consistency rubber) provides excellent high temperature resistance combined with low-temperature flexibility, chemical inertness, water repellency, dielectric properties and excellent resistance to environmental influences and weathering.

The curing

High-consistency silicone rubber (HCR) is cured via peroxide crosslinking or platinum-catalyzed addition curing.

All SILMIX® compounds are ready-to-use products that already contain the additives, crosslinkers and catalysts required for easy processing in your equipment.

They are easily cured by high temperatures and/or pressure during manufacturing. At our large testing facilities, we can test a special formulation to make sure our compounds work in your manufacturing process.

The manufacturing

Silicone can be processed in a variety of options. Our compounds are preformed to suit your equipment for compression molding, injection molding, extrusion and calendering.

At our large testing facilities, we can test a specific formulation catering to your manufacturing process.


Due to their special chemistry, silicones have unique properties such as chemical and flame resistance, high tear resistance and a wide operating temperature range. Stringent SILMIX® standards bring quality to each batch.
