polypropylene: The higher-formula-weight polypropylene, which accounts for the vast majority of commercial production and consumption worldwide, is synthesized through a completely different polymerization technique that involves introducing propene gas into an inert hydrocarbon solvent, typically heptane, which acts as the reaction medium.

Product Application of Polypropylene CAS#9003-07-0
Polypropylene (PP) is a thermoplastic material used in a wide variety of applications including packaging, labeling, textiles, etc. Due to high processability and low cost, PP is one of the most extensively produced polymers, especially, for auto industry. Pristine PP is resistant to photo-oxidation and thermal oxidation at moderate temperatures. However, PP is sensitive to various external aging environments (such as heat, light, and radiation), and, hence, has a relatively low service temperature.When PP is exposed to high temperatures or to an irradiation environment, the tertiary hydrogen atoms present in PP chains are susceptible to be attacked by oxygen. It is well known that PP oxidation depends on both light and temperature in outdoor aging conditions. PP can also be photo-degraded because several molecular chains are affected in the wavelength range from 310 to 350 nm.
