Introduction To HDPE Pipe Materials

The English name of high-density polyethylene is "High Density Polyethylene", or "HDPE" for short. HDPE is a thermoplastic resin with high crystallinity and non polarity. The appearance of HDPE in its original state is milky white, with a certain degree of translucency on its thin cross-section. PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). This polymer is non hygroscopic and has good water vapor resistance, making it suitable for packaging purposes. HDPE has excellent electrical properties, especially its high dielectric strength, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and low temperatures of -40F.
Although HDPE was introduced in 1956, this plastic has not yet reached a mature level. This universal material is still continuously developing its new uses and markets.
PE can be manufactured using a wide range of different processing methods. Including sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding, and rotational molding.
