Product Details
Polyethylene (PE) ranks as the most widely produced high-performance polymer material and leads global plastic production. Low-density polyethylene (LDPE) is mainly used in flexible products such as films and coatings, whereas high-density polyethylene (HDPE) is primarily applied in rigid products including bottles and containers; it can also be spun into fibers (known as ethylene fibers in some references) for manufacturing fishing nets, ropes and related products. Ultra-high molecular weight polyethylene (UHMWPE) exhibits a variety of exceptional properties, including excellent resistance to environmental stress cracking, low moisture absorption, high fatigue resistance and outstanding impact strength. It is commonly employed in textile machinery for producing wear-resistant and impact-resistant components like rubber joints, gears and washers.

Polyethylene is a thermoplastic resin formed through the addition polymerization of ethylene, with a molecular structure composed solely of carbon and hydrogen atoms. It is non-toxic, features outstanding low-temperature resistance (with a minimum service temperature of up to -100℃), and exhibits excellent chemical stability. Polyethylene can be processed into films, wire and cable insulation sheaths, pipes, various hollow containers, injection-molded parts, fibers, and other products, making it widely applied in agriculture, packaging, automotive, and many other industries.
