my country's high-density polyethylene industry chain has formed a gradual increase in output

High-density polyethylene (HDPE) is one of the subcategories of polyethylene. It appears as an opaque white powder or granules without special odor at normal temperature and pressure. It is odorless, non-toxic, light in weight, moisture-resistant and heat-resistant. It has the advantages of good toughness and easy processing, but it also has the disadvantages of low hardness and poor toughness. After years of development, my country’s high-density polyethylene preparation technology has been basically mature and can be roughly divided into solution method, slurry method, gas phase method, etc.

At present, my country’s high-density polyethylene industry chain has been formed. The upstream of the industrial chain is mainly raw materials such as ethylene, natural gas, and crude oil; the midstream is mainly the high-density polyethylene production industry, which is responsible for the production and manufacturing of high-density polyethylene; the downstream is mainly the application field, and high-density polyethylene is mostly used to produce films and sheets. materials, fiber products, pipes, doors and windows, injection molded products, hollow containers and other products.

From the upstream of the industrial chain, ethylene has become the main raw material for the production of high-density polyethylene. As the core material of the petrochemical industry, ethylene occupies an important position in the national economy. Driven by downstream market demand, my country’s ethylene production capacity has gradually expanded and output has increased. According to data released by the National Bureau of Statistics, my country’s ethylene production will be 28.975 million tons in 2022, an increase of 718,300 tons compared with 2021, and a year-on-year increase of 2.54%. my country’s ethylene production is gradually increasing, providing sufficient raw materials for the rapid development of the high-density polyethylene market.

High-density polyethylene pipes are widely used in construction, infrastructure, municipal administration and other fields due to their superior chemical and physical properties, light weight, strong pressure resistance, simple construction, and long service life. In addition, high-density polyethylene can also be used to produce various types of industrial accessories, toys, containers and other products through various methods such as extrusion and blow molding. Overall, my country’s market demand for high-density polyethylene is relatively large.

According to the “China High-Density Polyethylene (HDPE) Industry Application Market Demand and Development Opportunities Research Report 2023-2028” released by the Industrial Research Center span> shows that driven by downstream market demand, the production scale of my country’s high-density polyethylene enterprises has gradually expanded and output has increased. In 2022, my country’s high-density polyethylene output will be 11.6162 million tons, a year-on-year increase of 13.94%.

There are a large number of companies in my country’s high-density polyethylene market, and leading companies have emerged. At present, my country’s large-scale high-density polyethylene companies mainly include Dushanzi Petrochemical, Zhejiang Petrochemical, Zhenhai Refining and Chemical, Jinhai Chemical, Lianyungang Petrochemical, Wanhua Chemical, etc. Among them, Dushanzi Petrochemical has become my country’s largest high-density polyethylene production enterprise.

Industry analysts said that at this stage, my country’s high-density polyethylene industry is in a rapid development stage, but there are still some problems in the industry. For example, there is a lack of self-owned technology, serious product homogeneity, and a surplus of low-end products. In order to solve these problems, my country’s high-density polyethylene companies need to continuously improve their independent research and development capabilities, optimize production technology, and develop more high-end products, thereby promoting the further development of the industry.
