Q
Poor printability of polyolefin plastomer films
Q
Longitudinal retraction rate of polyolefin plastomer pipes exceeding the standard
A
Excessive retraction rate is caused by large internal stress or excessive orientation, and needs to be solved from temperature control, cooling rate, and hauling speed.
