E.S.C.R. Apparatus is used for determination of susceptibility of ethylene plastics to environmental stress cracking when subjected to certain conditions.
E.S.C.R. Apparatus is used for determination of susceptibility of ethylene plastics to environmental stress cracking when subjected to certain conditions. Bent specimens of the plastics each having a controlled imperfection on the surface are exposed to the action of a surface active agent, oils or detergent. The proportion of the total number of specimens that crack in a given time is observed.Inside bath is of S. S. and outside bath in M. S. with heat insulation.The heating system is having a RTD, Heater and Digital Temp. Controller ( PID )Max. Temperature 1500 °CMax. Temperature - R.T.,Resolution 0.10 °CAccuracy = + 0.50 °C
