Stress Crack Resistance


The most important function of a tank is containment!  That’s why it’s very important for a tank to be resistant to cracking.  AS/NZS 4766 requires that the tank material survives 500 hours of exposure to a harsh reagent without failure due to cracking.  This measure is known as ESCR (environmental stress crack resistance).

Alkatuff polyethylene offers an ESCR performance of over 1,000 hours ensuring years of reliable service.
