Special material for cars!

On April 1st, the reporter learned from Daqing Refining & Chemical Company that a polypropylene plant of the company successfully completed the trial production of the new product EA5076 with impact copolymer brand. After testing, all the indicators of the products have reached the standard, which indicates that Daqing Refining and Chemical Company has made a new breakthrough in the field of automobile special materials production.

In order to further broaden the market, Daqing Refining & Chemical Co., Ltd. actively participated in the research and development of new products in the automotive field. Previously, it successively developed and produced impact copolymer high melt index automotive materials EP548R, EP548S and high fluidity automotive special material EA5075. With their excellent performance, these three products won the wide favor of customers immediately after they were put into the market. Daqing Refining and Chemical Company has formed a series of impact copolymer product routes, and the product performance has reached the leading level in China.

In recent years, the R&D team of Daqing Refining & Chemical Co., Ltd. cooperated with many departments to deeply investigate the polypropylene automobile special material market and grasp the customer demand. "EA5076 products have higher melting index, better processing fluidity, high modulus, low odor and other advantages. They can be formed faster in the product processing process, save raw materials more effectively, reduce customer costs, and have a wider range of applications. They are mainly used to produce large-scale products such as automobile interior parts and door linings, as well as impact injection molding fields such as household appliances." Wang Guiyan, a researcher in Daqing Refining and Chemical Industry, told reporters.

In the process of industrial trial production, Daqing Refining & Chemical Co., Ltd. made full use of the previous production experience of impact copolymer products, continuously adjusted and optimized the operating parameters, accurately controlled the addition of hydrogen and other raw materials in the reactor, and encrypted the test frequency to ensure the stable product quality according to the performance indexes of EA5076 brand products. Because of the high melt index of this product, it is easy to cause the cutter winding of the extrusion granulator to stop, and the production personnel need to constantly optimize the control parameters of the extrusion granulator unit, which finally ensures the smooth operation of the extrusion granulator.

The successful trial production of EA5076 brand products laid the foundation for the serialization of polypropylene automobile special material production in Daqing Refining and Chemical Company. In the next step, Daqing Refining & Chemical Company will continue to have in-depth exchanges with customers, accurately grasp customer needs, increase investment in research and development of impact copolymer polypropylene products, and further enhance the economic benefits of enterprises.
