Crosslinked High Density Polyethylene (HDPE) was developed using electron beam radiation techniques. The crosslinked HDPE can be used as marine grade cross-linked HDPE floater pontoon material. Thermoplastic resin, HDPE blended with Ethylene Vinyl Acetate (EVA) in various weight percentage compositions before being radiate with electron beams irradiation. These composites showed significant changes in mechanical properties and temperature stability after the irradiations. From this study, the optimum dose for HDPE and HDPE/EVA blends will be obtain. This study also will provide the optimum irradiation dose in order to have a good, high strength and impact for the production of pontoon material. The present of EVA in the blend will act as impact modifier also being investigated in this study. From the study, the result showed some significant changes in thermal and mechanical properties after being irradiated with electron beam. The comparison of the result between these composite composition of irradiated and non- irradiated HDPE composite used for floater pontoon material is presented in this paper 1. Introduction High Density Polyethylene (HDPE) is a thermoplastic that provide a high strength-to-density ratio, and has been widely used in the production of plastic bottles, pipes, geomembranes, and plastic lumber. HDPE is known for its large strength to density ratio. The density of HDPE can range from 930 to 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than Low Density Polyethylene (LDPE) [1]. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and able to withstand somewhat higher temperatures (120 °C/ 248 °F for short periods) [2]. In order to obtain more excellent material properties of HDPE, Ethylene vinyl acetate copolymer (EVA) can be used to strengthen HDPE. Ethylene vinyl acetate copolymer (EVA) being used in this project are as an impact modifier for improving impact properties due to the presence of olefinic segments and interactive vinyl acetate groups in EVA[3]. In addition, the vinyl acetate concentration (VA %) may provide an additional variable to EVA for its role as impact modifier of HDPE.
