Recently, the industrial trial production of YU28G polypropylene (PP) special material jointly developed by Jinan Refining and Chemical Company and Beijing Chemical Industry Research Institute was successful
.
The special material has narrow relative molecular mass distribution, excellent spinnability and high monofilament strength, and can replace the imported PP special material for geotextiles
.
Aiming at the market demand, Jinan Refining and Chemical Company initiated the development and research of special materials for geotextiles, and tackled the problem of localization of PP special materials for geotextiles
.
In view of the fact that the existing PP products have good spinnability and low wire breakage rate, but low breaking stress, which leads to a decrease in the strength of geotextiles, the R&D team comprehensively analyzes the structure and performance of imported materials, repeatedly explores and adjusts the production process, optimizes antioxidants, Electrostatic agents and other composite components seek the best balance between spinnability and mechanical properties, and form a production plan for special materials for high-strength geotextiles
.
After repeated trials and feedback from downstream customers, the current product demand has stabilized.
From this month, it has been put on the shelves under the official brand, and the market expansion and price promotion work has been in full swing
