━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━from Table 3.In China, the proportion of PP used for wire drawing products is relatively large, This proportion is declining year by year, the proportion used in other fields is increasing, the consumption structure is changing, and the demand for special materials is growing rapidly. The demand for PP injection plastics in developed countries and regions such as Europe, America and Japan ranks first, followed by wire drawing and fiber, film and sheet, etc. the consumption structure of PP in China will also develop in this direction in the future

4. Market prospect

because PP products have the advantages of light weight, high impact strength, good environmental resistance (high and low temperature resistance, pollution resistance, humidity resistance, aging resistance) and long service life, the scope of application continues to expand, gradually replacing metals, other plastics, wood, natural and chemical fibers, etc., for packaging, transportation, textiles, building materials, furniture, household appliances, consumer goods and other fields. Therefore, in the next 10 years, the demand for PP will still maintain a high-speed growth trend, 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

4.1 the consumption of PP resin in wire drawing products (plastic woven bags, tarpaulins and ropes)

PP wire drawing products (plastic woven bags, tarpaulins and ropes, etc.) has always accounted for a high proportion in China, accounting for more than 60% annually, which is the largest consumption field of PP resin. In recent years, the development of PP injection molding products and packaging film has gradually changed the consumption structure of PP, and the proportion used for wire drawing has decreased, but it is still the largest field of PP resin consumption. In 2003, the domestic production of drawing grade PP was about 4million tons, accounting for 56.6% of the total consumption. In the future, wiredrawing products will develop to large and heavy-duty packaging bags, that is, container bags, and high-strength, antistatic, aging resistant and other packaging bags

in 2002, China's output of woven bags alone reached 25.5 billion. Except for 1.3 billion exported, the rest were domestic consumption, mainly in the fields of cement, chemical fertilizer, chemical industry, grain, feed, raw salt and so on. It is expected that the production and domestic apparent consumption of wire drawing products in China will continue to grow by 2010, but the growth rate will decline. It is estimated that the annual average growth rate in is%, and the annual average growth rate in is%. In 2005, the production, export and domestic apparent consumption of PP woven bags in China will reach 2.21 million tons, 150000 tons and 2.06 million tons respectively, 20 of which graphene and polyaniline composites will be the most studied, reaching 2.69 million tons, 200000 tons and 2.49 million tons respectively in 10 years

in addition, the demand for tarpaulins, ropes and other fields in PP wire drawing products has also increased rapidly

most of the raw materials used for wire drawing are supplied by China, and the domestic PP can fully meet the needs of woven products. The main brands are F401 and 2401 of Mitsui process and T30S of haymount process, which are the leading products of Chinese PP production enterprises and PP powder of small body process. Almost all domestic polypropylene production enterprises can provide PP resin for woven bag production. Due to the insufficient self-sufficiency of domestic PP resin, China also imports some PP wire drawing materials, mainly including f601, F301 and F401 from Japan, h436 and h730f from South Korea, h03sg from India and 500p from Saudi Arabia. Less plastic woven bags produced with imported raw materials are used for domestic consumption and more are used for product export. In addition, in China (mainly Zhejiang, Shandong, Jiangsu and other places), about 10000 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. Due to the large number of domestic wire drawing products processing enterprises, including large-scale modern enterprises and family workshop "underground" processing plants, the product quality varies greatly, and the market is relatively chaotic, which has brought some negative effects to the PP market

the demand for PP wire drawing products in China will remain large for a long time in the future, but the proportion will continue to decline. Therefore, domestic PP production enterprises should strive to make another effort to open the minds of visitors: traditional products can also have such a high output of special materials, and gradually reduce the proportion of wire drawing products, so as to adapt to the changes in market demand structure and achieve better benefits. Shanghai Petrochemical, Qilu Petrochemical, Yanhua and other enterprises have developed in this direction in the past two years and achieved good results

4.2 polypropylene fiber

polypropylene fiber is a market with great development potential for pp. in addition to being used as clothing fiber, industrial polypropylene fiber is an active variety. With the emphasis on project quality, the application of PP non-woven fabric in roads, reservoirs, dam construction, construction engineering, medical and other aspects will increase. It is estimated that the demand for polypropylene in the field of polypropylene fiber will increase by 5% in. At present, the main domestic brands include Shanghai Petrochemical y2600/1600/3700c, Fushun hy525, Maoming and other companies' Z30S, v30s, h30s, cs820, etc. Domestic output accounts for about 30% of the total demand and relies heavily on imports. Therefore, domestic production enterprises should appropriately increase the output proportion of fiber materials

4.3 injection molded products

China's PP injection molded products occupy the second place in the consumption of PP and are one of the areas with the greatest potential for PP demand in the future. It is mainly used for hard packaging (such as containers, turnover boxes, trays, bottle caps, etc.), transportation (such as car interior decoration, bumpers, battery shells, fuel tanks, etc.), daily consumer goods (such as kitchenware, furniture, washing machines, flower pots, suitcases, etc.), instruments and medical products (such as injectors, tool boxes, material pots), etc. There are many kinds of PP injection plastics with great differences in quality grades, including homopolymer, block copolymer, random copolymer, PP Alloy, etc., which can meet the requirements of products with different properties

in recent years, China's petrochemical enterprises have paid more attention to the development of injection plastics, successively developed or introduced a series of PP injection marks, and gradually introduced them to the market. At present, typical domestic brands include EPS30R, j340, K8003, k8303, 1340, 1440, v30g, m2101r, m700r, m180r, k7726, 1947, SP179, ev14r, HHP4, etc. Nevertheless, the output of PP injection plastic in China still cannot meet the demand, and more than half of it depends on imports. Imported brands are mainly from South Korea, Japan, Singapore, Europe, America and the Middle East. Typical brands include j340, bj730, 570p, ap03b, M1600, ay564, rp344r, b380g, h110ma, etc., including block copolymers and random copolymers. There are various brands with different Mi values in the market, the smallest is 0.8, and the largest is more than 30. Compared with imported materials, the MI range of domestic copolymers is too large (the MI of different batches of the same brand varies greatly), the production of processing enterprises is difficult, and the scrap rate is high, so that many enterprises prefer to spend more yuan/ton to buy imported materials instead of domestic materials. Take j340 of the same brand with the same production process for example, MI should be 1 9. The index of j340 produced by Korean Xiaoxing is 1.7 ± 0.3, while the range of domestic j340 is 0 3. The price of the former is about 500 yuan/ton higher, and some users still choose imported materials. Other domestic injection plastics also have such problems, which should be paid enough attention by domestic petrochemical enterprises and solved as soon as possible

in the automotive field, China's automotive demand has maintained a high growth rate of 30% for two consecutive years. In 2003, China's automotive demand was about 4.45 million vehicles, and the ownership was about 20million vehicles. It is estimated that in 2004, the demand for automobiles will be about 5.15 million and the number of automobiles will be about 25million. In the coming years, the demand will still maintain the momentum of rapid growth. The average consumption of plastic per vehicle in the world reached 105 kg in 2000, accounting for about 8 ~ 12% of the total vehicle mass, and the proportion of plastic used for cars is larger. It is estimated that the global consumption of polypropylene for automotive use will reach 2.8 million tons in 2005, and the demand for polypropylene in China's automotive industry will reach 134000 tons, of which about 30% will be used for bumpers. The market potential of PP auto parts is huge. As the main variety of automotive plastics, the demand for PP will also increase rapidly. Domestic Qilu Petrochemical has developed special materials for automobile bumpers and fuel tanks, and Yanshan and Shanghai petrochemical industries have developed special materials for automobile parts. In addition, some enterprises have developed PP modified materials. At present, the large domestic automobile and parts manufacturers mostly use imported special materials to produce auto parts. It is difficult for domestic materials to enter this market. Firstly, domestic materials should further improve the quality and stability of products, and secondly, they should also have certain advantages in price and service

in the field of household appliances, the PP injection plastic market is also large. For example, in terms of special materials for washing machine barrels, before 1997, it was the world of imported materials. Later, with the successful development of Yanhua k7726 and 1947 (used in Haier and other enterprises), domestic raw materials gradually gained a certain market share. Subsequently, Maoming developed HHP4 and hhp3, and Qilu developed ev14r, which is also gradually entering this market

in addition, the consumption of PP injection molded products in traditional fields, such as packaging, consumer goods and medical treatment, is also growing steadily

it is estimated that the domestic demand for PP injection plastic will reach about 1.9 million tons in 2005 and 3million tons in 2010. The market potential of PP injection plastics is huge, and it is one of the fields that domestic enterprises should focus on in the future
