Ultra-low ash polypropylene refers to polypropylene products with an ash content of less than 0.
The battery separator material of ultra-low ash polypropylene acts on the dry process lithium battery separator.
As a high-end polypropylene product with high attention in China, ultra-low ash polypropylene is not only highly dependent on imports, but also has a high price and the trend brought about by the development of the new energy industry, but the expansion of market demand is limited.
China's ultra-low ash polypropylene is 95% dependent on imports, and China's ultra-low ash polypropylene imports are mainly from South Korea's petrochemicals, Borealis, TPC,
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: copolymerized and homopolymerized
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
