Silicone rubber-based rubber mixes

Silicone rubber-based rubber mixes

14RР-2, 14R-6, 14R-15, 5R-129, IRP-1265, IRP-1266, IRP-1267 rubber mixes are based on SKT, SKTV, SKTV-1, SKTE silicone rubbers. The mixes are designed for manufacture of heat and frost resistant rubber products used in various sectors of the national economy. Grades 14r-2, 14r-6, 14r-15, 5r-129 are used for manufacture of gaskets and other molded parts operating in air environment with high ozone content and in electric field conditions with up to 10% deformation in fixed joints. Grades IRP-1265, IRP-1266, IRP-1267 are used for manufacture of molded sealing parts operating in air with high ozone content and in electric field conditions with up to 20% deformation in fixed joints.
