How much do you know about the raw materials of HDPE pipes?

PE pipes can be manufactured by different processing methods. Using ethylene as the main raw material, propylene, 1-butene, and hexene as copolymers, under the action of a catalyst, the slurry polymerization or gas phase polymerization process is adopted, and the obtained polymer is subjected to flash evaporation, separation, drying, granulation, etc. process to obtain finished products with uniform particles.Including such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotational molding.
HDPE high-density polyethylene plastic is now used, referred to as “HDPE”. It is a thermoplastic polyolefin produced by the copolymerization of ethylene. HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent.
PE has excellent resistance to most domestic and industrial chemicals. Certain classes of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes.
HDPE has very good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance at room temperature or even down to -40F.
