Fabrication and Study of Hardness Behavior on Gamma Irradiated Ultra-High Molecular Weight Polyethylene (UHMWPE) Plate

Over the decades, there has been an enormous development in the field of polymers, especially in areas of Ultra- High Molecular Weight Polyethylene. Ultra High Molecular Weight (UHMWPE) Polyethylene materials have exceptional properties like high impact resistance, durability and high thermal conductivity. It finds its application in conveyor lines, wear strips, Bearings, gears, pistons, valves, marine equipment. But very little research has been done in the characterization study of Gamma irradiated UHMWPE and also the effect of different melt temperature on the uniqueness of UHMWPE seems to be an interesting thing. In this work, we have fabricated UHMWPE plates irradiated with Gamma rays using injection molding with different injection parameters like injection Velocity, melt temperature and compaction Time. The hardness behavior of this fabricated gamma irradiated Ultra-High Molecular Weight Polyethylene was analyzed.
