Environmental Stress Cracking Resistance apparatus, designed as per ASTM D-1693 for ethylene plastics.
The E.S.C.R Apparatus is designed as per ASTM D-1693 to determine the Environmental Stress Cracking Resistance of ethylene plastics. Environmental stress cracking is one of the most common causes of failure in polyethylene products: when a plastic is under stress and in contact with certain chemicals or surfactants, fine cracks can form and grow over time, even at stress levels well below the material’s strength.
To run the test, notched specimens are bent, placed in a specimen holder and immersed in a reagent inside a temperature-controlled bath. The time taken for cracks to appear indicates the material’s resistance to environmental stress cracking. With six stations, a stainless-steel inner bath and a temperature range up to 200°C, the apparatus lets laboratories test several specimens at once for reliable polyethylene quality control and product development.
