Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications.
In China, wire drawing accounts for a large proportion with the share of 36.3% in polypropylene consumption structure. But recently, the demand for plastic injection products is increasing in various sectors, such as automobiles, home appliances, toys, daily necessities and industrial containers. As a result, the demand of polypropene in plastic articles has increased accordingly. In 2017, plastic products accounted for 33%.
Polypropylene are usually produced from four types of raw materials, namely, oil to olefin, coal to olefin, propane dehydrogenation and propylene. In 2016, polypropene produced by oil to olefin had the biggest proportion with the share of 63.32%. Although the share of oil to olefin decreased a little in 2017, it still dominated the market and at the same time, the proportion of other raw materials has increased.
