As a representative of modified plastics, polypropylene is widely used in textile, packaging, home appliances, electromechanical, transportation, construction and other industries. It can produce different products, such as knitted products, plastic film, pipe, fiber, injection molding products. In 2004, China's polypropylene production reached 2.5 million tons per year, but most of the high-grade polypropylene special materials still rely on imports, such as special packaging boxes and containers, automotive plastic parts, electronic and electrical plastic parts, various turnover boxes, containers. Engineering plastics required for plastic furniture, etc., need to be imported. In the market demand for modified polypropylene, the consumption of fiber and injection molded products has sprung up, growing at a double-digit rate. In the fiber products market, most of the production of medium and low-grade products use domestically produced materials, and the raw materials required for the production of high-grade polypropylene products such as fine denier, ultra-fine denier, thin non-woven fabric, and strong filament are mainly solved by import. It is expected that the proportion of polypropylene in fiber products to its total consumption will increase from 10% in 2005 to 14% in 2010. In the injection molding products market, domestic materials are equivalent to imported materials, domestic materials occupy the low-end market, and imported materials occupy the high-end market. The injection plastics market has great potential, and consumption is expected to increase from 1.48 million tons in 2005 to 2.52 million tons in 2010. In addition, the market prospects for blow molding container materials, high flow and high impact automotive materials, BO polypropylene heat sealing film and pressure pipe are promising.
