Product Description

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.

Testing the effect of cracking due to environmental stress is now become easy to determine using artificial means of temeprature creation through Presto's ESCR. Now creating the desired temperatures in side the laboratory becomes easy. I must thanks Presto for this.
