Polyethylene (PE) is the most widely manufactured high-grade polymer material and accounts for the largest share of global plastic production. Low-density polyethylene (LDPE) is mainly used in flexible applications, such as films and coatings, whereas high-density polyethylene (HDPE) is primarily employed in rigid products, including bottles and containers. HDPE can also be processed into fibers, known as ethylene fibers by Chemicalbook, which are used to manufacture fishing nets, ropes, and similar products.

Ultra-high molecular weight polyethylene (UHMWPE) exhibits several excellent properties, including outstanding resistance to environmental stress cracking, low moisture absorption, superior fatigue resistance, and high impact strength. These characteristics make it suitable for textile machinery components that require good wear and impact resistance, such as rubber joints, gears, and washers.

Polyethylene  Chemical Properties

Application

Polyethylene is a thermoplastic resin formed through the addition polymerization of ethylene, with a molecular structure composed exclusively of carbon and hydrogen atoms. It is non-toxic, offers excellent resistance to low temperatures, with a minimum operating temperature of up to -100°C, and demonstrates good chemical stability. Polyethylene can be processed into a wide range of products, including films, wire and cable sheaths, pipes, various hollow articles, injection-molded products, and fibers. Owing to these versatile properties and processing capabilities, it is widely used in agriculture, packaging, the automotive industry, and other fields.
