What is HDPE pipe jointing? – Manufacturing Methods
Polyethylene (PE) is by far the most common type of consumer plastic, and is used in many everyday materials. It is a thermoplastic product, which means that it can be melted into a liquid and then cooled back into a solid. Different processing conditions give rise to different grades of polyethylene that can be used…

HDPE Plastics – Key Technical Parameters and Practical Applications
HDPE Plastic (High-Density Polyethylene) is short for high-density polyethylene, a thermoplastic polymer belonging to the polyolefin family. Thanks to its low degree of molecular branching, HDPE has a high density (0.941–0.965 g/cm³), which gives it excellent mechanical strength, as well as high resistance to impact, chemicals, and moisture. HDPE Plastic has a hard, opaque white…
