Q

Heat-resistant polyethylene pipe longitudinal reversion rate exceeding standard (Variant: mass production scenario)

A

Excessive reversion rate is caused by large internal stress or excessive orientation, and needs to be solved from temperature control, cooling rate and haul-off speed. Targeted preventive measures need to be taken in different production scenarios.
