R&D and production of high-end polyolefin products urgently require technological breakthroughs

Against the background of overcapacity in domestic refining and achieving the goal of carbon peak and carbon neutrality, "reducing oil and increasing oil" has become a general trend
.

China's polyolefin production capacity will expand rapidly from 2020 to 2021, and there will be more than 10 million tons of new capacity in 2021
.
Although the output of polyolefins in China has grown rapidly, there is a situation in which the supply of general products exceeds demand and high-end products still need to be imported in large quantities

Polyolefin products have a wide variety of products with great differences in performance

Song Yanping said that China's polyolefin market will not only face huge development space and opportunities brought about by economic development in the future, but also face fierce market competition
.
With the steady development of China's economy, consumption upgrades and the continuous progress of urbanization, the market still has strong demand for high value-added products, and the adjustment of product structure to the high-end direction has become the consensus of domestic counterparts

However, multinational companies are more advanced in catalysts and polymerization technologies, giving them a strong advantage in the development and production of high-end products.
In addition, in recent years, they have accelerated their deployment in the Chinese market, making production closer to the market center and reducing freight costs.
And sales pressure will bring greater competitive pressure to the high-end development of Chinese enterprises
.
This requires the domestic polyolefin industry to strengthen innovation, develop high-end products, and improve core competitiveness

R&D and production of high-end polyolefin products urgently require technological breakthroughs

The research and development of high-end polyolefin products is a complex process that requires the joint efforts of multiple links
.
A breakthrough in core technology is a hurdle that cannot be bypassed

Take electrical grade polypropylene and POE products as an example, the domestic lithium battery industry has developed rapidly in recent years, and the domestic demand for electrical grade polypropylene used in lithium battery separators has grown rapidly
.
However, due to the high technical requirements for the production of lithium battery diaphragm raw materials, the core technology is monopolized by international companies, which makes the domestic development of polypropylene for lithium battery diaphragms relatively slow in China, and most of the raw materials rely on imports

POE products have good rheological properties, mechanical properties, UV resistance, and good low-temperature toughness
.
They are widely used in automobiles, wires and cables, household goods, toys and other fields .

High-performance catalyst technology, polymerization process technology, and product technology based on product structure and performance control are the basis for the high performance of polyolefin resins
.
The main difficulty in developing high-end products lies in the catalyst

Song Yanping said: "Catalysts are the core of the production process
.
High-end polyolefin products require high performance.
In recent years, although we have made some breakthroughs in the research and development of high-performance and core catalysts, the overall technology is still lacking, and we need to further develop it.
Independent research and development, promote the process of localization of core catalysts, improve the level of technology, improve product stability, and break the monopoly of foreign technology
.
"

With the development of the economy, the current market users' demand for polyethylene products tends to be high-end and differentiated
.
Song Yanping said that China's market development is very different, regional development is not balanced, and user needs in different regions are not the same
.
Some refining and chemical companies still have problems such as slow market response and insufficient production flexibility
.
Enterprises need to quickly conduct market research, judgment and decision-making according to their own conditions and device characteristics, flexible arrangements, overall coordination, improve market resilience, walk in the forefront of the market, and achieve synchronization of product production with market changes
.
In addition, market users also have higher requirements for the stability of high-end polyolefin products, as well as certain requirements on product prices, appearance and service guarantees.
It is also necessary to further strengthen process management, pay attention to follow-up service guarantees, and provide users with more Valuable service
.

Guided by the market, further extend the mid-to-high-end industrial chain

With the improvement of people's living standards, China's demand for high-end petrochemical products is increasing rapidly, and the high-end and characteristic development of chemical products will be the market choice
.

Technological breakthroughs are the key, and in-depth market research is the premise
.
To conduct high-end product research and development, enterprises need to strengthen the docking with regional sales companies, strengthen communication with customers, and develop in accordance with the characteristics of the regional market; establish a product evaluation system to be closer to market needs
.

Investigate the changes in product application fields, and implement technology substitution and upgrade development around high value-added, greener and more environmentally friendly polyolefin products.
For example, polyethylene can focus on metallocene film materials, PE100RC pipe materials, large-diameter pipe materials, PERT II, ​​BOPE; Polypropylene can focus on products such as low-odor, high-crystalline impact copolymers
.
Pay attention to the serialized development of characteristic products to win a broader market space.
For example, on the basis of existing medical grades, develop new products such as soft bag materials, stand-up bags, and blister materials to increase product coverage
.
Through continuous improvement of packaging, technical service level and product stability, brand products are created
.

Song Yanping said that the development of new products requires close coordination and cooperation in different links such as sales, production, and research and development in order to better grasp the needs of customers in the market
.
Through research and investigation in the sales link, customers' requirements for products are transformed into requirements for performance indicators, and targeted research and development are guided
.
R&D personnel need to have profound theoretical and practical capabilities, as well as the ability to integrate with production technology development, to improve the level of understanding of catalysts, polymerization processes and additives, and to grasp the relationship between the structure and performance of synthetic resins
.
In production, it is necessary to strengthen refined production management to maintain product performance and quality stability
.

In the future, petrochemical companies need to increase their independent innovation efforts, and the development of new chemical products with special characteristics will develop towards high-end development in the industrial chain with strong innovation capabilities, high efficiency and efficiency, safety, greenness and low carbon
.
According to market demand, we will expand and strengthen our competitive products, expand the market, and create new profit growth points
