HindiMAXSIL organosilicon rubber mixes for electrical industry
MAXSIL organosilicon rubber mixes, intended for the electrical industry, can be produced both with and without added curing agent. Depending on the purpose, MAXSIL rubber mixes are produced in the following grades: K-8, K-69, K-69 “D”, K-69T, K-69T “D”, K-673, K-1520, K-1520 “D”, FS-55-2. Working temperature range from -50 °С to +200 °С (K-673: up to +250 °С). MAXSIL rubber mixes are designed for manufacture of heat and frost-resistant insulation and sheaths of wires, cables, electrical insulating tubes, and sealing gasket materials and profiles. K-69T, K-69T “D” are designed for increased hardness cables. K-673 has increased heat resistance. K-1520 is designed for manufacture of heat and frost-resistant insulation and sheath of single-stage cure cables. FS-55-2 are designed for manufacture of heat and frost-resistant products in electrical and other industries operating in the environment of various fuels, oils, lubricants, and for insulation of cable and wire sheaths
