Environmental Stress Cracking Resistance Tester

Environmental Stress Cracking Resistance Tester

Product introduction

The whole test device is composed of five devices: sample holder, sample device, sample bending device, sample transfer clamp, and constant temperature bath. The equipment has a perfect structure and advanced technology.

Functional requirements: Stress cracking ability of resins and plastics mainly made of polyethylene.

Design standards

According to the test device recommended by GB/T1842-1999 and ASTM D1693: 1997 "Environmental Stress Cracking Test Method for Polyethylene Plastics", a set of experimental devices for environmental stress cracking test of polyethylene plastics was designed. This set of test devices retains the prototype device. Technical requirements, and innovative in structure.
