WebOver the past decade, high-density polyethylene (HDPE) materials have improved significantly and now meet more stringent performance standards. Some performance evaluation tests that once took only days to run now take months with today’s resins. One such performance criteria is Environmental Stress Crack Resistance (ESCR). WebAt room temperature the designer can choose from almost any of the available plastics but below –40°C there are a very limited number of plastics that are suitable and more importantly this number decreases rapidly as the application temperature decreases. The Application Requirements At extremely low temperatures other factors become important.
