Polyethylene belongs to the group of polyolefins. It is the most commonly used plastic in the world. Polyethylene is classified not only according to its density (LDPE, MDPE, HDPE), but also according to the length of its molecular chains (PE 300, PE 500, PE 1000) or strength classes according to ISO 9080 (PE 63, PE 80, PE 100). A significant advantage of the material is the excellent UV stability of the material colored black with carbon black
To join PE parts, they are welded together, since they cannot be glued or printed without pretreatment. All common welding devices such as hot air blowers or blowers, an Injectiweld or welding extruder are suitable for this purpose.
