Since the beginning of the 21st century, the work of modified engineering plastics in China has been carried out by leaps and bounds along with the stable and healthy development of the national economy. For more than a decade, the economic skill index has been steadily higher than that of express delivery. However, restricted by skill factors, the domestic modified plastics products are still dominated by middle and low-end products, and the high-end products mainly rely on imports. We have high hopes for the development of China' s engineering plastics work, The characteristics and problems of China' s engineering plastics work are summarized as follows.

I. The use proportion in the manufacturing industry is still relatively low

Compared with the development of modified plastics in foreign shopping malls, the proportion of plastics and steel used in German economic development is 63:37, that in the United States is 70:30, and the international average level has also reached 50:50. The work of modified plastics in China started late, and the use of modified plastics in large-scale planning has just started. Limited by production skills, the proportion of domestic modified plastics used in fine manufacturing industry is lower. The ratio of plastic steel used in China is only 30:70, which is far lower than the average level of developed countries and the world.

II. It has certain regional characteristics

The working area of modified plastics has a high degree of convergence, but it tends to be gradually lax. From the regional distribution of the total output and sales revenue of the modified plastics industry, the production and sales of modified plastics in China mainly converge in East China and South China, and the proportion of the total industrial output and sales revenue in central and southwest China is advancing year by year.

The regional distribution characteristics of modified plastics work are determined by the convergence degree and regional distribution characteristics of its inferior work. The dirty fields of modified plastics are mainly cars, car electronics, home appliances, construction, packaging, light industry, etc. Meanwhile, cars and household appliances are the primary use areas of modified plastics, accounting for more than 50% of consumption.

III. The planning of domestic modified plastics enterprises is generally small

Compared with international chemical giants, domestic modified plastic manufacturers do not have advantages in skills, planning and industrial chain, resulting in the lack of competitiveness of domestic modified plastic manufacturers in the field of high-end professional modified plastics. Although there is a large gap between the modified plastics produced by domestic enterprises and the modified plastics produced by international chemical giants in terms of functions, the gap has gradually narrowed due to the support of national policies and the continuous progress of enterprise R & D capabilities. In addition, domestic enterprises also have some advantages unmatched by international chemical giants, such as low cost, close to customers, flexible response, customized services, etc, The above advantages enable excellent domestic enterprises to gradually expand the proportion of shopping malls in shopping malls.

IV. The proportion of shopping malls of multinational enterprises in China is relatively high

At present, there are thousands of enterprises engaged in the production of modified plastics in China, but only more than 70 enterprises (with a production capacity of more than 3000 tons) are planned, with a total production capacity of more than 2million tons. In terms of production capacity, domestic enterprises account for about 73% and foreign or joint ventures account for about 27%. However, from the perspective of market share, the market share of domestic enterprises is only 30%, while that of foreign enterprises is as high as 70%.

V. backward skills and comparative advantages in raw material cost selection

Although the varieties of modified plastic products are complex, from the composition of raw materials, they are combined with the five general plastic resins POM, PC, PBT, PA and PPE. The price trends of the five general plastics and the crude oil price trends are the same, indicating that the upstream enterprises have strong ability to transfer capital. This work feature determines that an integrated enterprise with upstream resources will obtain certain cost advantages. Domestic modified plastics enterprises have not yet started to the stage of front-end and rear-end integration, and are bound to control the cost of raw materials.

Vi. shopping malls are showing structural surplus

Domestic modified plastics enterprises started late, with backward skills, and their production capacity mostly converged in the field of general-purpose large products. Due to certain skill barriers, it is difficult to enter the high-end field, resulting in a certain surplus of work in the low-end field, while the high-end field needs to import from abroad, presenting the so-called structural surplus situation.

VII. The key to the competition lies in the modified skill formula

At present, the mainstream modified production technology is the physical modification technology based on filling, blending and reinforcement. Once the modified formula used for filling, blending and reinforcement is selected, the specific operation requirements for inferior production equipment are not high. This technical feature determines that the key process for the production of modified plastics lies in the planning of modified formula. From the current situation, the original formula of general-purpose large variety modified plastics is exposed in the market, while the formula of high-function professional modified plastics is in the hands of leading enterprises in various sub sectors.

VIII. Heavy asset operation

Compared with other work, the modified plastics work has the characteristics of large investment in fixed assets. Its equipment investment has the characteristics of large investment and slow effectiveness. Generally, the construction cycle of a standardized modified plastic production line takes about half a year, and the amount of equipment investment is huge. If it is necessary to advance the output, maintain stable quality and advance product precision, it is necessary to select large-scale equipment imported from abroad, and the equipment investment price is not cheap! The return cycle is long, which requires more support and subsidies from the government.

IX. cars and home appliance robots are important engines for work

At present, the use of modified plastics in the field of household appliances and cars in China accounts for more than 50%. Therefore, the development of household appliances and cars will have a great impact on the market demand for modified plastics. However, with the development of new energy cars in recent years, the continuous progress of domestic modified plastics skills and the gradual expansion of use planning, the impact of the development of household appliances and cars on the work of modified plastics will gradually decline. The launching of new work is a hot direction that major modified plastic enterprises attach importance to. For example, in recent years, UAV, VR, robot high-end consumer goods, sports goods and other new work!
