Abstract— Continuing our previous researches on UHMWPE (Ultra-High- Molecular-Weight Polyethylene) based implant material and its fusion with Ca-alginate, we describe new methods for preparing Ca-alginate blended UHMWPE samples and how we extended the testing of the prepared samples. If sufficient content of Ca-alginate can be achieved and the Calcium-alginate blended UHMWPE can be made, it might lead to an implant material which can promote bone formation. Earlier result shows that the Calcium–alginate contentwill be formed in the structure of UHMWPE. Using our new modified methods we can make polyethylene samples with sufficiently tough alginate content which can withstand washing and sterilization as that is shown in the paper. Since we had modified the UHMWPE specimens with Ca-alginates we carried out different types of wear testing on the prepared samples.
Keywords— UHMWPE, Na-alginate, Ca-alginate.
