According to insiders of Zhenhai Refining & Chemical Company, on March 30, Zhenhai Refining & Chemical Company successfully produced environmentally friendly high-melt impact polypropylene M100RHC for vehicles. HR catalyst. High-melt impact polypropylene is a high-end polypropylene product. Due to the difficulty of production, the domestic market is basically occupied by large foreign companies.
Previously, the melt index of automotive polypropylene produced by Zhenhai Refining & Chemical Co., Ltd. was 60, and the melt index of new products reached 100, which not only refreshed the company's highest record of melt index of polyolefin products, but also successfully used domestic catalysts to replace imported agents to achieve New breakthroughs in core technology.
Due to the new product M100RHC's melting index breakthrough device and the highest record of actual production history of the extruder, it has greatly affected the stable operation of the reactor and the extruder, making production operation control more difficult than ever. Under the careful guidance of technical management personnel, after a day of nervous and orderly adjustments, 300 tons were successfully produced.
Highlighted performance advantages
This product has the characteristics of excellent environmental protection performance, super high flow performance, good rigidity and toughness balance performance, etc. It is suitable for large-scale parts, thin-walled products and plastic modification, especially in the field of automotive modification and other outstanding advantages The market prospect is good.
The melt index is generally higher than 30g / 10min. The high melt index means high fluidity, which can improve the injection of large parts and increase the yield. Zhenhai Refinery's new product M100RHC has a melt index of up to 100. The melt flow rate, mechanical properties and processing properties are more superior, which can better achieve thin wall weight reduction, shorten the molding cycle and reduce energy consumption.
High-flow polypropylene products can release volatile organic compounds (VOC), which are harmful to human health, to varying degrees at higher temperatures, which has become one of the urgent problems for automotive materials. The new product M100RHC also takes into account the improved odor on the basis of increasing the melt index, which has a lower odor and is more environmentally friendly.
