Study of change in properties of high-density polyethylene induced by radiation and marine exposure

Plastics have replaced many traditional materials, such as wood, glass and metal, and become an irreplaceable part of our modern existence in this contemporary era. All plastics have complex chemical structures composed of atoms. The arrangement of atoms with respect to one another directly influence the properties of the plastics. High-Density Polyethylene well known as HDPE is a thermoplastic polymer produced from the monomer ethylene which has various applications. Plastics weathering is commonly caused by various processes such as photooxidation, photothermal oxidation, mechanical abrasion, hydrolysis and biodegradation
