Characteristics of PE
Generally, PE has the following characteristics:
- It is possible to control the density of PE by copolymerization of α-olefin and to produce various types of PE.
- PE shows good processability, and can be molded by various methods such as extrusion, blow molding, and injection molding.
- Due to excellent mechanical properties especially at low temperature, PE is used for various applications in cold climates.
- PE has good electrical property, weatherability, and chemical resistance, consequently PE is used for various applications such as electrical insulation, bottle with certain chemicals.
