Yangzi petrochemical research institute and plastic factory jointly developed the water supply and water use of polypropylene tubing special materials project recently passed the provincial appraisal of jiangsu provincial science and technology department.

After signing, the expert review committee agreed that the project for the first time in the polypropylene HY - POL process device through the copolymerization sequence structure distribution optimization, the control of low melt flow index and the brand switching technology development and long-term stability of the formula design and so on, successfully developed and produced water supply used special polypropylene pipe material. This is the first time the yangzi petrochemical in the industrial device has successfully produced more than twenty thousand tons of special pipe material the high added value, the performance of the detection performance to imported similar products, the production of parts per/PPR product structure characterization of completely consistent with that of foreign products, non-toxic tasteless, long life and other characteristics.

With yangzi petrochemical independent intellectual property rights of the successful development of this special pipe material, not only improve the domestic polyolefin products dedicated material proportion and scale, to enhance the product competitiveness, and also can replace imported products, has significant social benefits and economic benefits. At present, the technology has applied for national patent. This special material has not only satisfied the demand of domestic market since it was brought to market, but also shortened the gap with similar products abroad. After five industrial production, yangzi petrochemical in 2003 has accumulated the raw material 2. 40,000 tons, a profit of more than 60 million yuan.
