Product Introduction

The Environmental Stress Cracking Resistance (ESCR) Tester is a high-precision laboratory instrument designed to evaluate the susceptibility of thermoplastics, particularly polyethylene and other polymers, to environmental stress cracking. By simulating real-world chemical and mechanical conditions, this tester provides quantitative data on material durability, enabling manufacturers to optimize product formulations and ensure long-term performance under stress.

The instrument can perform both bending beam and constant load tests in a controlled temperature and chemical environment. It features an automated multi-specimen testing platform, integrated temperature control, and advanced data acquisition software to provide reliable, repeatable, and traceable results.

Applications

Testing the environmental stress cracking resistance of polyethylene, polypropylene, and other thermoplastics.

Assessing material performance in aggressive chemical environments, including oils, surfactants, and alcohols.

Applicable to automotive, packaging, consumer goods, and industrial plastics.

Used for research, quality control, and material certification.
