High Density Polyethylene (HDPE) is a type of thermoplastic polymer known for its immense strength to density ratio. It is made from petroleum and is exceptionally resistant to chemicals, moisture, and ageing. Because it does not absorb moisture, it is also impervious to mold and rot. With strong heat fusion and jointing capabilities, it is extremely durable and offers a long-lasting option for various applications. HDPE is widely used in various industries like packaging (especially in the production of plastic bottles), pipe fittings, automotive components, and more due to its versatility and recyclability. Furthermore, it is considered environmentally friendly due to its low emissions during manufacturing and easy recyclability.
