Introduction

The environmental stress cracking (ESC) apparatus is suitable for determining the ESCC resistance of polyethylene homopolymers and other copolymers containing less than 50% (m/m) of 1-olefin monomers and no more than 3% (m/m) of functional non-olefin monomers under specified conditions. This apparatus, designed by our company based on the recommendations of GB/T1842-2008, "Polyethylene Plastics Test Method for Environmental Stress Cracking," and ASTM D1693:2008, "Standard Test Method for Environmental Stress Cracking of Ethylene Plastics," is used to determine how the stress acting on the specimen and the thermal history of the specimen affect the ESCC resistance of the material.
