Polyethylene (PE)
Description
Polyethylene (PE) is one of the most widely used thermoplastic polymers in the world. It is valued for its flexibility, chemical resistance, moisture resistance, and impact strength. Depending on its density and molecular structure, polyethylene can range from soft and flexible (LDPE) to rigid and strong (HDPE). It is commonly used in packaging films, plastic bags, bottles, pipes, containers, tanks, and industrial applications. Polyethylene is lightweight, cost-effective, and recyclable, making it suitable for both consumer and industrial markets.
