Shanta Engineering offers Environmental Stress Cracking Tester for determining ethylene plastic susceptibility. This apparatus determines susceptibility of ethylene plastics to environmental stress cracking when they are 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, oil or detergent. The proportion of the total number of specimens that crack in a given time is observed by this machine. The Environmental Stress Cracking Tester for determining ethylene plastic susceptibility features the following accessories:
