Environmental Stress, Cracking Resistance

Model PTE013

Environmental Stress Cracking is the brittle failure of a polymeric material from a combination of stress and environment. The frequency of failure depends on the material properties, the environment conditions, its level and type of stress under certain conditions of stress, and in the presence environments like wetting agents, soaps, detergents, oils. Blow molded polyethylene container exhibit involuntary failure by cracking at stresses substantially below those that would cause cracking in the absence of such environments.Test methods of ESCR are clearly described in various standards that can be used to calculate the environmental stress- crack resistance of plastic containers, which is the precise of container design, blow-molding conditions, resin, post treatment and various other factors that can influence this property.

Hoverlabs  Environmental Stress Cracking Resistance is widely used to measure the cracking resistance of plastics due to environmental stress, which is necessarily the abstract of various parameters.  It is influenced by the design of the container, molding conditions, treatments during and after production and other related factors that affect this. This test procedure helps plastic manufacturers to separate and identify the effect of the related factors on stress crack resistance of the container.
