Abstract:

Effect of nucleation agentboth on the toughness and the orientation of PET were studied. Rapid nucleationof melted PET caused by nucleating agent resulted in the decrease in grain sizeand it can improved the toughness of the PET. Both the elongation and the areaunder stress-strain curves of the PET strapping band increased significantly.Among these agents, 0.5wt% Aclyn is the most effective for elongation increaseand the tensile strength is not changed for PET/Aclyn strapping bands. Both thedecrease in orientation degree and the increase in crystallinity were observedafter adding nucleating agents in PET strapping bands. The increase in theresidual ratio of the relaxation stress with the increase of the crystallinity proved that the crystallization could inhibits thedevelopment of the stress relaxation.
