Dushanzi Petrochemical Company has successfully independently produced terpolypropylene products. It was learned on November 2 that Dushanzi Petrochemical Company has successfully produced terpolypropylene products with high added value for the first time, which are classified according to fiber strength. It has basically mastered the core production technology of this product and reduced its dependence on foreign patentees. At present, the unit load is 18 T/h, and the production is normal

terpolypropylene is a terpolymeric random polypropylene containing comonomer 1-butene and ethylene. It has better low-temperature heat sealing performance, wider heat sealing window, better transparency and adhesion resistance than the second level governments. Therefore, it is suitable for making high-grade film materials and is widely used in cooking bags, composite films, cigarette packaging films, heat shrinkable films Processing and manufacturing of metal composite films

in June this year, Dushanzi Petrochemical Co., Ltd. successfully conducted trial production with foreign patent dealers. Due to the addition of butene, the isotacticity of the ternary copolymer product decreases, and the melting point temperature decreases. When the polymerization temperature is close to the melting point of the polymer, it is easy to cause sticking and blocking in the polymerization system, which is dangerous and difficult to produce. Since October 27, the company has optimized the production conversion process, revised the production conversion operation card, optimized the operating parameters of the extruder and optimized the additive formula in the extrusion section in combination with the last trial production experience. By using a new catalyst, slowly adjusting the feed rate of butene-1 and ethylene, and adjusting the control parameters of reactor level, caking was prevented, and the product was qualified on October 30

in order to speed up the development and industrialization of new products and optimize the product structure, Dushanzi Petrochemical Company listed the terpolypropylene product as a key project of new product development, and implemented the transformation of butene-1 injection system in 2015. The device has the conditions to produce terpolypropylene product because of poor contact between the sample and the anvil
