Environmental Stress Crack Resistance Test Bath for Molded Parts

Thermostatic bath for evaluating stress cracking of molded polyethylene and other plastics under bent strip conditions in surfactant. Used by molders of closures, fittings and containers to rank resin grades and process quality.

Specification

Notched or bent specimens are immersed in a surfactant solution held at constant temperature while time to crack is recorded. Racks hold many samples at once so batch comparisons are practical. A circulating heater maintains the bath within tight limits.

Features

• Stainless steel tank with insulated lid
• Circulating heater, 50 deg C
• Holds 10 or 20 specimens
• Digital timer and temperature display
• Bent strip holders included
