OKT increased fire resistance organosilicon rubber mix
OKT increased fire resistance organosilicon rubber mix is available both with and without added curing agent. The rubber mix is non-toxic, it has FV 0 flammability class. Products made from OKT rubber mix have the following properties: high tracking and erosion resistance, good electrical insulating properties in wet condition, high resistance to ozone, UV rays, precipitation and pollution, weather temperature fluctuations. OKT rubber mix products working temperature conditions are from -50 °С to +200 °С. OKT increased fire resistance rubber mix is intended for manufacture of various rubber products. It can also be used for manufacture of polymer housings of high-voltage insulators and other electrical products.
