High Density Polyethylene (HDPE)

Polypropylene is one of the most widely used polymers in the world and the largest consumer of propylene. The name of this product is polypropylene (PP) and its chemical formula is CH2-CH (CH3) n. Polypropylene is made from propylene polymerization under relatively mild temperature and pressure conditions and in the presence of the famous Ziegler-NATO catalyst. The presence of this catalyst forms an isotactic polymer that is able to crystallize by about 90%. Polypropylene is a thermoplastic polymer used in a wide range of applications, including film and sheet, blow molding, injection molding, food packaging, textiles, laboratory and medical equipment, pipes, industrial and construction applications, and automotive components. In addition, polymer produced from propylene monomer is typically resistant to chemical solvents, bases, and acids which is the characteristics of this polymer.
