Polypropylene Production Cost

Polypropylene, also known as PP or polypropylene, is a thermoplastic polymer that is often used in a wide variety of applications. It is prepared via chain-growth polymerization from the monomer propylene.

Polypropylene belongs to the group of polyolefins, which is partially crystalline and non-polar. Its properties are similar to that of polyethylene, but it is more heat resistant and slightly harder. It is a mechanically rugged material, which has a high chemical resistance and is white in color. Polypropylene is the second-most widely manufactured commodity plastic after polyethylene. It is often utilized in packaging and labeling.

Polypropylene is in several aspects alike to polyethylene, especially in solution behavior as well as in electrical properties. The properties of polypropylene may depend on the molecular weight, molecular weight distribution, crystallinity, type, the proportion of comonomer (if used), and the isotacticity. In isotactic polypropylene, for instance, the methyl groups are oriented on one side of the carbon backbone. This arrangement makes for a greater degree of crystallinity and results in a stiffer material, which has greater resistance to creep than both atactic polypropylene and polyethylene.
