SShR type rubber mixes

SShR type rubber mixes are based on silicone rubbers and are produced in the following grades: SShR-73-2K, SShR-73-2KV, SShR-73-2KV-S. The rubber mix is non-toxic, non-explosive. Designed for injection molding and compression molding production of gaskets for SNTs, SNO type plug connectors operating in air, electric field environment in the temperature range from -60 °C to +200 °C with up to 20% compression strain.
