Environmental Stress Crack Resistance Tester for HDPE Bottles

Test rack with pressurised bottles in a heated detergent bath to find the time to stress crack failure of HDPE containers. Used by bottle makers for household chemical, lubricant and agrochemical packaging per ASTM D2561.

Specification

Bottles are filled with a surfactant solution, pressurised internally at a small differential pressure and kept at 60 deg C in a thermostatic bath. The time to first leakage shows the resin and moulding quality. It reveals the effect of wall thickness and base design on stress cracking.

Features

• Stainless steel bath with heater and circulator
• Multi station pressure manifold for 10 bottles
• Regulator and gauges for internal pressure
• Temperature control within +/-1 deg C
• Timer per station with failure detection
