Thread Content

Recently, Yanshan Petrochemical successfully produced high-density polyethylene 6903B, a special basic resin for environmentally friendly "stone paper", with an output of 150 tons, and has begun to put it on the market. This is the company's first official mass production after a successful small trial at a domestic environmentally friendly paper company in September. It marks that the process of the 6903B grade has been finalized and has the ability to meet market demand in batches. It is understood that "stone paper" is a new environmentally friendly material between paper and plastic. It is made of high-density polyethylene special resin combined with a large amount of limestone and other additives through a special process. This "stone paper" not only has the same writing performance and printing effect as plant fiber paper, but also has the tear-resistant, folding-resistant, waterproof and mildew-proof properties of plastic packaging. It can replace most traditional paper and traditional plastic packaging. Because the production process of "stone paper" is short, energy consumption is low, output is high, cost is low, and it is non-toxic, odorless, recyclable and naturally degrades, and does not produce secondary pollution, it has good market prospects. Yuan Chunhai, deputy manager of Yanshan Petrochemical High-Tech Company, said that previously, because no company could produce the high-density polyethylene basic resin required for stone paper, several large domestic environmentally friendly paper companies all used imported raw materials. At the end of last year, Yanshan Petrochemical began to conduct trial production of "stone paper" special materials. By analyzing the structure and performance of imported products, combining the process characteristics of Yanhua's low-pressure polyethylene equipment and repeatedly optimizing the trial production plan based on customer trial results, after two trial productions, a qualified "stone paper" special material product was finally produced. After trial, customers said that Yanshan Petrochemical products fully meet the usage requirements. “The successful development and production of "stone paper" special materials is the first time in my country's petrochemical system. Yuan Chunhai said that Yanshan petrochemical products have certain brand advantages and at the same time can ensure stable supply. They are very competitive compared with imported products, so they have become the first choice of domestic environmentally friendly paper companies. At the same time, the successful trial production of "Stone Paper" special resin not only enriched Yanshan Petrochemical's low-pressure polyethylene product brands, but also improved the flexibility of product structure adjustment. At present, the company is further improving its technical service level, combining the advantages of the MPRC team, focusing on developing more new users, and creating conditions for the further expansion of market production of "stone paper" special materials.
