Professional guidance for HDPE sheets (what is HDPE sheet):
HDPE sheets are engineering plastics made from high-density polyethylene, which is a thermoplastic polymer extracted from petroleum. It is a common plastic in the world, with many characteristics that make it suitable for various applications. Polyethylene sheets are odorless, non-toxic, and have a wax like feel. They have excellent low-temperature resistance (up to -70~-80 ° C at low temperatures), good chemical stability, and can withstand most acids and alkalis (not acid resistant oxidation performance). They are insoluble in general solvents at room temperature and have a low absorption rate. HDPE sheets also have characteristics of mold resistance and acid resistance, making them suitable for food processing and storage. Therefore, it is also widely used in various industries.Name: HDPE board| ITEM | RESULT | UNIT | PAREMETER | NORM USED |
