Environmental Stress Cracking Resistance Tester- ESCR

Environmental Stress Cracking Resistance Tester

Environmental Stress Cracking Resistance Tester is a unique test cabinet designed to detect the change in the physical characteristics of the plastic material and to ascertain the actual working life of test samples at environmental stress. It is important resin property caused by tensile stresses.

The Presto Environmental Stress Cracking Resistance tester is accompanied by standard accessories such as cutting die, glass tubes, digital temperature controller and foils. The aesthetic appeal is enhanced by the autumn gray and blue combination finishing and bright chrome/zinc plating to ensure resistance to corrosion.

Presto offers an Environmental Stress Cracking Resistance Tester specially designed for evaluating the effect of environment on blow molded polyethylene containers. In the presence of certain substances like, soaps, oils, detergents or wetting agents plastic containers may exhibit mechanical failure by cracking. A similar effect is witnessed under conditions of stress and cracking occurs at appreciably lower stress than in the absence of such environments or conditions.

The Presto Environmental Stress Cracking Resistance Tester is widely used for measuring the environmental stress cracking resistance of plastic containers, which is essentially the summation of various parameters. It is influenced by the container design, resin blow molding condition, treatments during and after production and other factors that affect this property. This test procedure helps plastic manufacturers to isolate and identify the effect of the related factors on stress crack resistance of the container.

The Presto environmental stress cracking resistance tester has been made in accordance with industry standards that include ASTM D1693-15 which provides highly accurate testing results. This lab testing equipment consists of a temperature range (for silicone oil) from ambient to 250 degree Celsius whereas the temperature range (for water) will be available from ambient to 90 degrees Celsius.

This mild steel duly powder-coated lab testing instrument has been equipped with rapid heaters for uniform and homogenous heating and maintaining the temperature inside the chamber. It comes with an integral water drain system & integral water drain system along with inbuilt calibration features with reference to the master PID controller.

Users can easily conduct environmental stress-cracking resistance tests with the help of this testing machine. It comes with the provision of a set value (SV) and process value (PV) on the temperature display. With the help of this lab testing equipment, one can easily test their products effectively in different environmental conditions and test the change in the physical characteristics of the products.
