Construction and Analysis of Plastic Extruder Machine for Polyethylene Plastic Waste

Abstract

Polyethylene plastic waste is such hazard object in the world, while the benefits of this plastic rubbish are prodigious. An extruder machine is one of the great ways to reduce huge amounts of plastic waste not only to the manufacturing companies which recycle the plastic waste but also to the small society. This extruder machine was created to overcome the problems faced by all countries about plastic waste in land or in ocean. The results of extruded plastic waste were solid filament that can be utilized for some valuable stuff made by plastic. From this study, experimental test was applied by heating the plastic waste with different temperatures of 150, 160, 170, 180, 190, 200, 210, 220, and 230°C. As a result, the best temperature to heat the polyethylene plastic waste is 190°C according to surface roughness test and digital caliper measurement.

High Energy Release-high Retraction Smart Polymer Fibers used in Artificial Muscle Fabrication

“…To develop muscle fibers, polymers of low transitional temperatures together with thermoplastic elastomers such as thermoplastic polyurethane (TPU) and ethylene vinyl acetate (EVA) blended with high stiffness polymers such as polylactic acid (PLA) have been widely reported in the literature [7][8][9][10]. The blend of such materials exhibits the network points and molecular switching phase that have been generated through covalent bonds, intermolecular interactions and cross-links [11].…”
