  • Detail

In August, China's plastic market is still stable.

the golden autumn and August will soon pass, and the hot and busy days seem to come to an end. On the eve of September, HC reviewed the development of the plastic market in August with everyone. Since August, the global economy has been facing uncertainty. The slowdown of global economic growth has basically become a reality. As a result, downstream consumption expectations have been reduced, and crude oil has fluctuated sharply after the decline. Domestic petrochemical policies are facing adjustment. The overall development of China's plastics market is still tepid and stable

injection molding machine injection degree did not decrease, and the modified PBT was successfully placed in the top position

. Injection molding machine is also known as injection molding machine or injection machine. It is the main forming equipment for making plastic products of various shapes by using plastic forming molds with thermoplastic or thermosetting materials. It is divided into vertical type, horizontal type and full electric type. The injection molding machine heats the plastic and applies high pressure to the molten plastic to make it shoot out and fill the mold cavity

the injection molding machine has the ability to form plastic products with complex shape, accurate size or dense texture with metal inserts at one time. It is widely used in national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture, culture, education and health, as well as various fields of people's daily life. Today, with the rapid development of the plastic industry, injection molding machines play an important role in both quantity and variety. Their total production accounts for 20%--30% of the total plastic molding equipment, making them one of the fastest growing and largest production models in the current plastic machinery

because modified PBT can help brands protect frozen or dry food, meat and cheese products from production to consumption, it has the advantages of high heat resistance, toughness, fatigue resistance, self-lubricating, low friction coefficient, weather resistance and low water absorption, and has also attracted wide attention in recent years. In the search ranking in August, it successfully surpassed engineering plastics and ranked second

modified PBT plastic refers to the addition of small molecular inorganic or organic substances into polymers (resins) to endow them with certain properties (machining properties) or improve their properties through physical or chemical actions. For example, toughening, reinforcing, plasticizing, flame retardancy, etc., and the plastic has become fresh through modification technology. Among them, the application and development potential of modified PBT plastic is the greatest in the field of automobile and household appliances

modified PBT plastic is the most important lightweight material for automobiles. It can not only reduce the mass of parts by about 40%, but also reduce the procurement cost by about 40% according to the technical specification for utilization of building glass jgj113 ⑵ 003%. Therefore, its use in automobiles has increased rapidly in recent years. At present, the automotive interior parts have been basically plastic, and the automotive development of "replacing steel with plastic" is driving the continuous development and innovation of modified PBT plastics in a broader field of automotive applications

the demand for plastic additives has become a hot spot for purchasing.

. A large class of additives used for plastic molding products, including plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, antistatic agents, anti mildew agents, colorants and brighteners (how to find some "substitutes" see pigments), fillers, coupling agents, lubricants, release agents, etc

Since the 1960s, due to the rise of petrochemical industry, the plastic industry has developed rapidly, and plastic additives have become an important chemical industry. According to the differences in the composition of plastic varieties and the use of plastics in various countries, the consumption of plastic additives is about 8% ~ 10% of the plastic output. At present, plasticizers, flame retardants and fillers are the largest amount of plastic additives

plastic machinery and molds have always been the highlight of the development of the plastic industry. The perfection of plastic machinery directly affects the quality, output and cost of plastic semi-finished products or products. Therefore, it must be able to adapt to the changes of temperature and stress in the process of plastic mixing and processing, as well as the resulting changes in the properties of molten materials, and to adapt to special conditions such as chemical corrosion and mechanical wear. In recent years, the specialization of plastic grade, the development of engineering plastics, the emergence of composite materials, and the development of technologies such as large-scale, lightweight and thin-walled plastic product structure require plastic machinery to meet the following requirements: complete sets for the purpose of product production; High speed, labor saving and automation to improve product production efficiency; Ensure the minimum precision of product specification and quality error; Low energy consumption, less land occupation, easy and safe operation and maintenance

all kinds of tools and products used in our daily production and life, ranging from the base and body shell of machine tools to the shell of a embryo head screw, button and various household appliances, are closely related to molds. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products

supply information: demand determines supply. PBT ranks first in supply and demand.

Jinan trial fund is required to be listed among them to determine supply. In the supply data in August, we can see that PBT has successfully occupied the top in supply information in response to market demand. PBT can also be called thermoplastic polyester plastic. In order to be applicable to different processing industries, additives are generally added or mixed with other plastics. With different proportions of additives, products of different specifications can be manufactured. Because PBT has heat resistance, weather resistance, drug resistance, good electrical properties, small water absorption and good gloss, it is widely used in electronic appliances, auto parts, machinery, household products, etc

in recent years, due to the development of domestic related industries, the demand for PBT resin has increased year by year. With the rapid development of China's national economy, especially the rapid development of the downstream electronic industry and automobile industry, the PBT market demand is growing rapidly

abs plastic is mainly a blend or terpolymer of acrylonitrile, butadiene and styrene, which is a tough and rigid thermoplastic. ABS resin is the polymer with the largest output and the most widely used at present. It organically integrates the various properties of PS, San and BS, and has excellent mechanical properties of toughness, hardness and rigid phase balance. ABS can be divided into general grade (including various impact grade), flame retardant grade, heat-resistant grade, electroplating grade, transparent grade, structural foaming grade and modified ABS according to different uses. The universal level is used to manufacture gears, bearings, handles, machine shells and components, various instruments, computers, tape recorders, televisions, and other shells and toys; Flame retardant grade is used to manufacture electronic components, such as computer terminals, machine housings and various household electrical appliances; The structural foaming grade is used for manufacturing the covers of electronic devices, etc; The heat-resistant grade is used for manufacturing automation instruments and motor housings in power plants; Electroplating grade is used to manufacture automobile parts, various knobs, nameplates, decorations and daily necessities; The transparent grade is used to make the degree plate, the food plate in the refrigerator, etc

hdpe is a thermoplastic polyolefin formed by ethylene copolymerization. Although HDPE was introduced in 1956, this kind of plastic has not yet reached the mature level. This general-purpose material is still developing its new applications and markets. The latest supply of HC360 plastics shows that the market demand for HDPE has also begun to increase. The polymer is non hygroscopic and has good water vapor resistance, and can be used for packaging. HDPE has good electrical properties, especially the high dielectric strength of insulation, which makes it very suitable for wires and cables

conclusion: Generally speaking, China's plastic market in August continued the development state of July, with no ups and downs and still showing signs of stability. If the international economic and political situation does not change significantly, it is expected that China's plastic market will not change significantly in the near future
