Yangzi Petrochemical enters PP high-end market

The independently developed high-performance YP-R503 successfully achieved industrial trial production The high-performance PPR pipe special material independently developed by Yangzi Petrochemical Company has successfully achieved industrial trial production on its polypropylene plant. This new YP-R503 grade pipe material has reached the level of similar foreign products and will become the leader in polypropylene pipe special materials for the domestic market.
The special polypropylene material has a wide range of relative molecular mass distribution and good comonomer sequence structure distribution. It is very suitable for the production of PPR pipe, and the product has both good rigidity and toughness, excellent processing performance, and can meet 63 mm or more. Caliber water pipe production needs. The YP-R503 produced by the pilot test has been tested by the National Building Materials Testing Center and has reached the standard of short-term hydrostatic test under 1000 hours and long-term thermal stability test under 8760 hours.
PPR pipes have excellent performance and have been widely used in various pipe systems. The demand has grown rapidly. However, this pipe requires higher raw material polypropylene and is more difficult to produce. Although many brands have been developed in the country, the production scale is mostly small and it is difficult to meet the demand. In particular, there is a shortage of large-caliber PPR pipe raw materials. Basically dependent on imported materials, the cost is higher.
Yangzi Petrochemical has accumulated years of experience in the research and development of polypropylene pipe special materials, through a large number of small trials and pilot tests, through the screening of new catalysts, the design of process routes, the optimization of process conditions, the mechanical performance testing and structural characterization, A series of designs and experiments, such as trial production and processing applications, have mastered the entire production process of the special material.
At present, the designed capacity of Yangzi Petrochemical's polypropylene plant is 200,000 tons/year, some of which are used for the production of special materials. Prior to this, PPR pipe special materials have been producing F401. In order to smoothly achieve the switching of F401-R503, Yangzi Petrochemical Research Institute conducted a simulation switching test of F401-R503 on the pilot plant, and conducted the stable operation, activity size and activity release rule, hydrogen modulation process, ethylene feed, etc. of the device. System tests and analysis have created better technical conditions for the first stable use of new catalysts and product development. In the process of industrialization adjustment, the results of the pilot study were basically verified in industrial installations to ensure the smooth progress of industrialization tests. YP-R503 has high added value and large market capacity. Its successful trial production marks Yangzi Petrochemical's entry into the high-end market for polypropylene pipe materials.
