At present, China's high-end polypropylene special materials with high foreign dependence include two categories
.
High crystallinity polypropylene (HCPP) can be divided into two categories: copolymerization and homopolymerization
.
High Stiffness Polypropylene (HSPP) increases the toughness of the compound and helps compound companies minimize plastomer loading, thereby simplifying formulations
.
In 2019, the consumption of HSPP in the Chinese market was about 350,000 tons, mainly used in downstream fields such as automobiles (50%), toys (30%) and household appliances
.
In the Chinese market, 95% of ultra-low ash polypropylene is imported
