What is HDPE sheet: HDPE sheets are engineering plastics made from high-density polyethylene, which is a thermoplastic polymer extracted from petroleum. It is one of the most common plastics in the world, featuring characteristics that make it ideal for various industrial applications.
These polyethylene sheets are odorless, non-toxic, and have a wax-like feel. They exhibit excellent low-temperature resistance (up to -70~-80°C), superior chemical stability, and can withstand most acids and alkalis. With low absorption rates and mold resistance, HDPE is widely utilized in food processing, storage, and mechanical manufacturing.
