Does your company produce terpolypropylene? －－Welcome to share with us [Haichuan. Chemical Pioneer]

It’s only 2,000 yuan more – by how much will the processing costs increase? Could you tell me?

A demand of 80,000 tons at 2,000 per ton means a difference of over 100 million. The capacity is not large, so it’s not possible to rush into this; I’m not sure what the cost of renovation will be

Project Name: Development of a Complete Industrial Technology for Terpolymerized Polypropylene • Award Level: First Prize for Scientific and Technological Progress at the Group Company level • Achievement Highlights: Through optimizations such as the use of catalysts and external electron-donating systems, the polymerization mechanisms for terpolymerizing ethylene, propylene, and butylene, polymerization and granulation process conditions, additive systems, and product quality standards, this project enabled the industrial production of terpolymerized polypropylene products on a large scale, in a continuous and stable manner, using gas-phase polymerization facilities. In May 2011, a well-known domestic manufacturer of polyolefin shrink film requested to purchase the terpolymerized polypropylene product F5606, developed by Yanshan Petrochemical, despite previously insisting on using only imported materials for their shrink film production. What changed the attitude of polyolefin shrink film manufacturers? 　　“In recent years, Yanshan Petrochemical has intensified its efforts in scientific and technological research, developing a complete set of industrial technologies for terpolymerized polypropylene. The products manufactured using these technologies meet international advanced standards in terms of key parameters such as mechanical properties, optical properties, processability, and transparency, making them fully capable of replacing imported products. ”A responsible official from Yanshan Petrochemical said. 　　Create products that meet market needs but are not available elsewhere. Yanshan Petrochemical’s main polypropylene product used to be binary copolymer materials, which enjoyed good market demand and high selling prices. However, with the market’s increasing demands for product quality and environmental protection, this product is no longer the high-end product it was a few years ago, nor is it the preferred choice for many polyolefin shrink film manufacturers. “This makes us realize that we must accelerate the adoption of technological upgrades and create products that meet market demands and are not available elsewhere. ”A company official in charge said. After extensive market research, they focused their attention on terpolymer random copolymer products. 　　Terpolymerized polypropylene possesses properties such as low-temperature heat-sealability, transparency, and anti-adhesion, which meet the increasing demands for higher heat-seal performance in fast packaging speeds. It is widely used in high-end packaging industries such as food, cigarettes, cosmetics, and apparel. At that time, there were hardly any domestic manufacturers of high-quality ternary heat-seal film materials, and meeting domestic demand relied mainly on imports. Although the selling price of imported materials is more than 2,000 yuan per ton higher than that of ordinary binary copolymer products, the market demand in the domestic market remains strong. 　　This inspired the researchers at Yanshan Petrochemical to think that if it were possible to use the existing polymerization facilities to develop and produce terpolymerized polypropylene products, this would undoubtedly become a new source of revenue growth for the company. 　　Master a technology and capture a market. At that time, the technology for terpolymerized polypropylene was monopolized by foreign companies, and domestic firms attempted to overcome the challenges associated with terpolymerized low-temperature heat-seal films, only to fail in all attempts. Moreover, there are no successful international precedents for converting ethylene and propylene binary polymerization plants to produce terpolymer products. 　　“There is no existing experience to draw on; we have to figure things out as we go, exploring while designing. ”Recalled relevant researchers from Yanshan Petrochemical. To upgrade the associated metering, control, instrumentation, and other systems, they added a butylene feeding system ； Lacking performance metrics for ternary products, they started with basic analysis, compared the product preparation methods, selected optimal catalyst formulations, and optimized the polymerization process. 　　After countless trials and improvements, they finally selected the optimal parameters for polymer extrusion granulation and developed a reasonable production plan for terpolymerized polypropylene. 　　After the pilot production of the industrial plant, issues such as the caking of powders and excessively long transition times when switching from binary to terpolymerization processes became obstacles to product quality control. To address these issues, the research personnel at Yanshan Petrochemical studied catalyst systems used in industrial plants, summarized the rules governing terpolymerization, and developed polymerization and granulation processes. As a result, they established a set of methods for analyzing the content of copolymer monomers in terpolymerized polypropylene as well as the initial heat-sealing temperature of film products. They also designed processes for online analysis of butene, smooth transition between different product grades, and removal of residual butene. 　　In May 2010, the first batch of tripolymerized polypropylene products was tested for film extrusion using a small polypropylene film machine. After numerous improvements, the development of a complete set of industrial technologies for terpolymerized polypropylene using the Innovene process was successful, enabling high-capacity, continuous, and stable industrial production of terpolymerized products and filling a gap in this field in China. 　　To enable the new products to quickly capture the domestic market, Yanshan Petrochemical has set quality standards for the terpolymerized polypropylene series, based on international high-end products. Products such as F5606, a special material for heat-sealing layers of heat-shrinkable films, F5006, a special material for heat-sealing layers of cigarette films, and C5608 and C5908, special materials for heat-sealing layers of cast films, have been introduced one after another, quickly becoming highly sought-after products in the market with demand exceeding supply. 　　“The development of this set of technologies is just a small step taken by Yanshan Petrochemical in its efforts to produce terpolymer products. How to carry out in-depth development is the top priority for future work. ”A responsible official from Yanshan Petrochemical said. (Ming Yibing)

Dushanzi Petrochemical Company successfully conducts pilot production of new terpolymerized polypropylene products. Source: Yaxin Net. Author: Li Zhiqiang. Publication time: 2016-07-07 10:37:24. Share: According to Yaxin Net (reporter Li Zhiqiang), on July 4, the research institute of Xinjiang Dushanzi Petrochemical Company was testing two products, TF1005 and TF1007; these are new terpolymerized polypropylene products that the company has recently succeeded in producing on a pilot basis. New ternary copolymer products with high added value are widely used in the processing and manufacturing of food packaging materials such as retort pouches, composite films, cigarette packaging films, heat-shrinkable films, and metal composite films. Thanks to thorough preparation for this trial production and stable process control, the trial production plan was successfully carried out. Qualified TF1005 and TF1007 products were produced on June 23 and 26 respectively; their melting points are comparable to those of the leading domestic products, and their performance parameters meet the required standards. To accelerate the development and industrialization of new products, optimize the product portfolio, and enhance economic efficiency and market competitiveness, Dushanzi Petrochemical Company designated terpolymerized polypropylene products as key targets for new product development. In 2015, a modification was carried out on the butene-1 feeding system, enabling the plant to produce terpolymerized polypropylene products.

Regular production of high-hardness grade polypropylene terpolymers at Dushanzi Petrochemical in Xinjiang 2017-05-10 15:46 On April 30, the production of TF1007, a terpolymer product from Line 35 of Dushanzi Petrochemical’s polypropylene plant, was completed, and the plant successfully switched to producing S1003. Thus, the company has achieved routine production of its high-performance polypropylene tercopolymer grades. During these 10 days of production of the terpolymer product, 4,000 tons were manufactured. The research institute of Duhu Petrochemical determined that the initial heat-sealing temperature of the distillate pellets is 113 degrees, which is at an advanced level in China. The new teropolymer product is a teres random polypropylene containing the comonomers 1-butene and ethylene; it exhibits better low-temperature heat-sealing properties, a wider heat-sealing range, superior transparency, and anti-adhesion characteristics compared to binary copolymerized polypropylene. As such, it is suitable for use in high-quality film materials, and is widely applied in the processing and manufacturing of food packaging applications such as retort pouches, composite films, cigarette packaging films, heat-shrinkable films, and metal-composite films. At present, only two companies in the country, including Dushihua Petrochemical, are capable of producing it, and its marginal profit per ton is 2,000 yuan higher than that of ordinary materials. In recent years, Duhu Petrochemical has been continuously developing high-end products in line with its competitive strategy for chemical products, which focuses on low costs, differentiation, brand building, and high-end positioning. In June 2016, a terpolymer product was developed in collaboration with the patent holder, and independent pilot production was successfully carried out again in October of the same year. To address the issues of sticky materials and pipe blockages that often occur in polymerization systems, the workshop discussed production plans in advance and developed standard templates for switching to alternative products. By adjusting the control parameters for the reactor level, reducing the cycle time of the product discharge system, and increasing the flow rate of the purge gas in the powder discharge line, the amount of terpolymer lumps was significantly reduced, reaching the best level since the start of production.

With such huge profit margins, people will surely flock to it.
