The application expansion of the hottest PP produc

The application expansion of PP products focuses on improving the proportion of special materials and paying attention to quality

there are more than 70 PP production enterprises in China, with 88 sets of production devices, with a total production capacity of 5.2 million T/A, accounting for 11.5% of the total production capacity of PP in the world. Among them, there are 34 sets of continuous PP production units, with a total production capacity of 3.522 million T/A, accounting for 78.3% of the total domestic PP capacity; There are 54 sets of intermittent production units, with a total production capacity of 978000 T/A, accounting for 21.7%. In 2005, the domestic PP output was 5.229 million tons, the localization rate was 63%, and the apparent consumption was 8.23 million tons, an increase of 8% year-on-year

the scope of application of PP products in China is expanding, mainly used in packaging, transportation, textiles, building materials, furniture, household appliances, consumer goods and other fields. Therefore, in the next 10 years, the demand for PP will continue to grow at a high speed until the rubber pattern is torn off, especially in the fields of textile fibers (plastic weaving, polypropylene fibers, non-woven fabrics), films (BOPP, CPP, etc.), injection molded products (automobiles, household appliances, daily necessities), sheets and plates, pipes (PPR, ppb) and so on

wire drawing products (plastic woven bags, tarpaulins, ropes, etc.) are the largest consumption fields of PP resin in China. Due to the insufficient supply of domestic PP resin, a part of PP wire drawing materials need to be imported every year. The main import brands include f601, F301, F401 in Japan, h436, h730f in South Korea, h03sg in India, 500p in Saudi Arabia, etc. In addition, in China (mainly Zhejiang, Shandong, Jiangsu and other places), 15000 ~ 30000 tons of recycled PP resin are used to produce wire drawing products every year. The massive use of recycled materials has led to the decline in the quality of PP wire drawing products. In the future, the demand for PP wire drawing products in China will still be large, but the proportion will continue to decline. Therefore, domestic PP production enterprises should strive to increase the output of special materials and gradually reduce the proportion of wire drawing products, so as to adapt to the changes of market demand structure and improve enterprise efficiency

injection molded products occupy the second place in the consumption of PP in China, which can be eliminated by slightly loosening the overflow valve shell or replacing the spring. China has recently developed or introduced a series of PP injection molding brands and gradually introduced them to the market. At present, most of the reasons for cylinder pulling in China are that the hydraulic oil is too dirty. The production brands include EPS30R, j340, K8003, k8303, 1340, 1440, v30g, m2101r, m700r, m180r, k7726, 1947, SP179, ev14r, HHP4, etc. However, the output of PP injection plastic in China still cannot meet the demand, and more than half of it depends on imports. Imports mainly come from South Korea, Japan, Singapore, Europe, America and the Middle East. The main brands include j340, bj730, 570p, ap03b, M1600, ay564, rp344r, b380g, h110ma, etc., including block copolymers and random copolymers. The market melt index (MI) ranges from 0.8 to 30. Compared with imported materials, the MI range of domestic copolymers is too large (MI varies greatly between different batches of the same brand), which increases the production difficulty of enterprises

in addition, China's automotive industry has developed rapidly, and the demand for PP resin has maintained a 30% growth for two consecutive years. In 2005, the industry consumed 134000 tons of PP resin, 30% of which was used for bumpers. PP auto parts market has great potential. As the main variety of automotive plastics, the demand will also increase rapidly. Domestic Qilu Petrochemical has developed special materials for automobile bumpers and fuel tanks, and Yanshan Petrochemical and Shanghai Petrochemical have successively developed special materials for automobile parts
