Gelonghui, April 18: Hengli Petrochemical (600346.SH) said on an interactive platform that 1. Listed companies have no plans to enter the oil and coal mining business. 2. Adhering to the idea of high-tech, market-based, sustainable and green development, the company has built a technological innovation system covering the entire industrial chain. By continuing to deepen industry-university-research cooperation, forming industry-university-research alliances, continuously increasing investment in R&D, cultivating a team of innovative R&D talents, overcoming many “stuck neck” technologies, and obtaining a large number of international and domestic core patents. Relying on the R&D platform carefully built over the years, focusing on the development path of market differentiation, high-end technology and business integration, and concentrating superior resources, the company continues to make breakthroughs in cutting-edge technology and cutting-edge product development for differentiated functional materials. For example, the subsidiary Kanghui New Materials successfully independently developed and mass-produced a 3.9 micron ultra-thin carbon strip substrate, with an annual production capacity of 6,000 tons, making it the first and only manufacturer in the industry to produce this type of film; the three new products of “elastic cotton-like polyester filament,” “non-grey-dyed polyester filament,” and “low-shrinkage flame retardant polyester industrial yarn” developed by the subsidiary Hengli Chemical Fiber passed provincial certification. The overall technical level of the first two products is leading in China; the “high uniformity ultra-soft polyester fiber” product overall The technology is at the leading level in the country, filling domestic gaps, etc. 3. On the one hand, the company optimizes operations, reduces costs and increases efficiency, strengthens the exploration of the entire industry chain, and organizes production according to the principle of maximizing efficiency, and “good oil means oil, yifang, yifang means chemical” to achieve balance in production and marketing, smooth operation, and maximum efficiency. On the other hand, the company relies on the “Big Chemical” platform to continuously empower and develop new materials over the years to accelerate the production capacity layout of downstream high-end chemical materials, achieve “excellent chain, extend chain, and repair chain” of the industry, optimize the company's industrial structure, and continuously enhance the company's overall competitive strength. The company's key projects will enter the peak production period one after another this year. The company will also achieve a significant increase in the production capacity of new downstream chemical products, including high-end fine chemicals, optical films, electronic films, lithium battery separators, battery electrolytes, composite fluid collector substrates, photovoltaic backplate substrates, etc., effectively enhancing the company's core competitiveness.
