HDPE

What Is High-Density Polyethylene (HDPE)?

High-Density Polyethylene (HDPE) is a thermoplastic polymer known for its high strength-to-density ratio. It's produced from petroleum and exhibits excellent resistance to chemicals, impact, and moisture, making it suitable for various applications, including packaging, pipes, and injection-molded products.
