Title:
METHOD FOR EVALUATING INJECTION PHYSICAL PROPERTY OF PLASTIC RESIN, AND POLYETHYLENE RESIN SUITABLE FOR INJECTION MOLDING
Document Type and Number:
WIPO Patent Application WO/2019/039839
Kind Code:
A3
Abstract:
The present invention relates to a method for evaluating an injection physical property of a plastic resin, and a polyethylene resin suitable for an injection molding process and, more particularly, to a novel method for evaluating an injection physical property of a plastic resin, which, when a particular plastic resin is processed by an injection process, can accurately derive injection suitability of the plastic resin and injection pressure in the injection process through a physical property value measured by using a resin sample, and a polyethylene resin suitable for injection molding.
