Heavy polyethylene EX3:
Polyethylene (EX3 (GM 5010 T2N) is a colorless heavy polyethylene (HDPE) colorless copolymer PE80 class. EX3 material with good ESCR and impact resistance suitable for the production of pipes for drinking water, agriculture and sewage, as well as a variety of fittings They are suitable.
Polyethylene has a very simple structure, so it is simpler than all commercial polymers. A polyethylene molecule is a long chain of carbon atoms with two hydrogen atoms attached to each carbon atom.
Heavy polyethylene has a higher crystallinity than other types of polyethylene due to the structure of the polymer chain; Therefore, it has a more compact structure and has a higher density, which is why it is called heavy polyethylene. The density of heavy polyethylene is between 0.95 and 0.97 grams per cubic centimeter.
High-density polyethylene has branched polymer chains, so the intermolecular strength in chains is high and its tensile strength is higher than other polyethylenes. The reaction conditions and the type of catalyst used in the production of HDPE polyethylene are effective. For the production of branched polyethylene, the polymerization method with Ziegler-Nata catalyst is usually used.
