Product Description of Polyethylene CAS#9002-88-4
Polyethylene (PE) is the world’s highest-output polymer and dominates global plastic production. LDPE is mainly used for flexible products such as films and coatings, while HDPE is primarily applied to rigid items including bottles and containers, and can also be spun into fibers for fishing nets and ropes. UHMWPE boasts excellent environmental stress cracking resistance, low moisture absorption, high fatigue resistance and superior impact strength, making it ideal for wear- and impact-resistant textile machinery components like rubber joints, gears and washers.

Product Application of Polyethylene CAS#9002-88-4
Polyethylene (PE) is a carbon-hydrogen thermoplastic resin produced via ethylene addition polymerization. It is non-toxic, with excellent low-temperature resistance (down to -100℃) and good chemical stability. Processable into films, cable sheaths, pipes, hollow products, injection-molded parts and fibers, it finds wide application in agriculture, packaging, automotive and other industries.
