The latest development of polyurethane industry and its market forecast
(1) when the melt is injected into the cavity of the mould cavity, it is subjected to a certain orientation effect in the circumferential direction. In addition, the temperature of the billet blowing is lower than that of the extrusion blow molding, the orientation effect generated by the blowing expansion can be more retained, which helps to improve the strength of the container.
(2) the accuracy of the container size (especially the neck screw thread size) is high: it is easy to ensure the uniformity of the thickness of the container wall, and the size of the container is uniform.
(3) vessels do not form a joint, without dressing, generally do not produce (scrap scrap produced by extrusion blow molding is usually 5%~30%).
(4) the sliding bottom module can be set on the blow mould, so the design of the bottom of the container is more flexible.
(5) more suitable for the formation of rigid plastic containers and wide mouth containers.
(6) the container has a high gloss, and transparent polymer is used to form the container.
