How to Stop HDPE Tanks, Crates & Pipes from Cracking (ESCR Failure)?

HDPE Environmental Stress Crack Resistance (ESCR) Solutions

Quick Answer: Siya Polymer's HDPE grades and compounding support are selected and processed to improve Environmental Stress Crack Resistance (ESCR), reducing slow-crack failure in water tanks, crates, pipes and chemical containers under long-term load.

Why This Happens

HDPE products that hold constant load or are in contact with detergents, oils or chemicals — water storage tanks, crates, drums, pipes and chemical containers — sometimes fail months after installation through slow, brittle-looking cracks, even though the same material passes a normal short-term impact test. This is Environmental Stress Cracking (ESC), and it is one of the most misdiagnosed field failures in HDPE products because it looks like a material defect when it is actually a combination of stress, contact with certain chemicals and insufficient ESCR in the grade or process being used. It's a serious problem for manufacturers of tanks, crates and pipes where a single field failure can mean a costly recall or liability claim. Siya Polymer & Speciality Chemicals helps HDPE processors select and stabilise the right grade for genuine long-term stress-crack resistance.
