Rubber compound IRP-1377 NTA TU 38 0051166-2015

heat-oil-petrol-aggressive rubber

is intended for the manufacture of rotating shaft seals and other sealing parts operating in air with a high ozone content, CIATIM-221 lubricant in the temperature range from minus 50 to plus 150ºС, in saturated steam at temperatures up to plus 150ºС, in NGZh-5U liquid in the temperature range from minus 55 to plus 125ºС, in water and solutions of acids and alkalis with a mass fraction of up to 20% in the temperature range from plus 4 to plus 100ºС, in the environment of technical ethyl alcohol - in the temperature range from minus 50 to plus 70ºС.

Heat-oil-benzo-aggressive-resistant rubber is more heat-resistant and technologically advanced compared to IRP-1287.

From a mixture of rubber IRP-1377 NTA, sealing parts are obtained with a 1,2-2,0 times increased service life.
