Research Of UHMWPE Material For Injection

PP and PE were used to improve the flowing properties of UHMWPE in the research, so that the UHMWPE blends could be processed through injection. It showed that UHMWPE and PP are inconsistent polymers. Though UHMWPE/PP blends have high fluidity its mechanical properties is reduced greatly. POE-g-MAH was chosen as compatibilizer of UHMWPE/PP blend and it has modification effect on the blends. Compare UHMWPE/PP blends, UHMWPE and PE have more better consistency than UHMWPE and PP due to their same molecular structure, so PE was used as processing modifier of UHMWPE. The modification effect and mechanism of several kinds of PE to UHMWPE was studied, and on this base, UHMWPE materials for injection were studied. In addition, different lubricants, including little molecular an polymer wax were individual used in the blends and their modification effect and mechanism were also studied. In the end, the blends were injected through injection machine successfully.
