Ultra-high molecular weight polyethylene plays an important role in China's aerospace, national defense, marine engineering, petrochemical industry, medical equipment and other fields. Artificial joints, elevator guide rails, oil pipelines ... these materials all use ultra-high molecular weight polyethylene.
The short-flow and efficient manufacturing technology of ultra-high molecular weight polyethylene products is a brand-new technology, which replaces the traditional screw processing method based on shear rheology with the eccentric rotor processing method pioneered in the world, making it possible to produce high-performance ultra-high molecular weight polyethylene efficiently.
The emergence of new technologies has solved the international problem of high-efficiency and high-quality processing of ultra-high molecular weight polyethylene, and boosted the technological level of related industrial chains by leaps and bounds. The production efficiency of ultra-high molecular weight polyethylene, which is extremely difficult to process, has been improved by more than 10 times. Replacing imported products in high-end applications will produce remarkable economic benefits in the future.
In May last year, the technology-related intellectual property rights successfully landed in Foshan at a transfer price of more than 20 million yuan. At present, the team is committed to the nationwide promotion and application of this technology. The following listed companies deserve attention:
Fosun Technology (000973)
The company is mainly engaged in the production and sales of all kinds of advanced polymer new materials. Focusing on the development orientation of new materials industry, the company adheres to the business strategy of "three-wheel drive" of technological innovation, refined management and capital operation, strengthens the technical attack and marketing of related new materials, accelerates the development of high-end functional films, and increases investment to form new growth points. The new polymer material industry engaged by the company belongs to the national strategic emerging industry, and has formed an industrial layout with dialysis materials, photoelectric materials and barrier materials as the framework. Differentiated products such as polarizing film, roughened electrical film, ultra-thin capacitor film, metallized film for safety capacitor, breathable film, non-porous moisture permeable film and composite plastic woven material are advanced in technology, quality and performance, and are leading enterprises in market segments.
The new polymer materials developed by the company, such as lithium ion battery separator, polarizing film and capacitor film, have been well-known in domestic and foreign markets, and gradually formed an industrial layout with dialysis materials, electrical materials, optical materials and barrier materials as the framework. The PVDF membrane backboard project and composite intelligent energy-saving membrane project developed by the company for crystalline silicon solar cells mark the high-end development of the company to the new energy and new materials industry.
Hua Mao Shihua (000637)
The company has many years of production technology, R&D technology and talent pool, equipped with a stable professional R&D technical team, established two provincial-level fine chemical technology R&D centers in Guangdong Province, and has more than 40 proprietary technologies. In recent years, the company has focused on project development, new product development, tapping potential and increasing efficiency, improving quality and increasing efficiency, saving energy and reducing consumption. We have intensified the research and development of new technologies and products, and successfully developed and applied high-tech production technologies such as special white oil, polypropylene, ethanolamine, liquefied petroleum gas and MTBE, among which special white oil and isobutane can replace imported products.
The company's main products are polypropylene, low aromatic solvent oil, ethanolamine, liquefied petroleum gas plastic modified products and so on. Products are sold to more than ten provinces and regions such as Guangdong, Guangxi and Hainan. At present, the company has more than170,000 tons/year of polypropylene and 500,000 tons/year of gas classification. Among them, polypropylene is the largest batch of small bulk polypropylene production equipment in China, and gas separation equipment ranks second in the same industry in China. Based on the main business of petrochemical industry, the company vigorously develops Z olefin post-processing, oil refining and deep processing, fine chemicals and unrefined ethylene and other fine chemicals.
