In the s Bell Laboratories devised a test for ESCR Thus, for example, constant-strain tests (such as the ASTM D the bent-strip test) have been criticized because of stiffness variations among specimens The environmental stress crack (ESCR) induced by chemical agents plays a significant role on material performances. ESCR problems get more pronounced in the summer, because of several factors related to increased heat and humidity. In this contribution, in-depth studies have been carried out on different medical plastic materials, such as polycarbonate, copolyesters, ABS, acrylics, rigid thermoplastic polyurethane and their blends Plastic containers comprising two or more layers wherein the external or the internal layer consists essentially of a metallocene-produced medium density polyethylene resin, said plastic container having respectively an external or internal gloss of at least 40 and an environmental stress crack resistance, as measured by the time to rupture, of at least 30 days The stress cracking is more severe with detergent, bleach, motor oil and some industrial chemical packaging. Thus, for example, constant-strain tests (such as the ASTM D the bent-strip test) have been criticized because of stiffness variations among specimens Therefore it is essential to consider ESCR in the early part design phase. High performance polymers such as PPSU have an inherently good resistance towardsESCR Testing. ESCR or Environmental Stress Cracking Resistance Tester is a highly unique and advanced design test equipment which is used to estimate the quality of plastic and examine the sustainability of polymer under stressful conditions ESCR Testing. A present limitation of ESCR testing is its inability to isolate the yield-stress property as a parameter independent of the polymer's mechanical properties.
