Recently, the Chinese petrochemical giant YZSH Petrochemical Technology Group successfully solved the problems of long glass fiber reinforced polypropylene (PP) special material products such as pelletizing and performance fluctuations, low production load, etc., and achieved the goal of stable production and high output. 1,500 tons of high-quality products have been smoothly Offline, meeting market demand, and becoming a new profit growth point.
The polypropylene (PP) base material used for the reinforcement of long glass fiber is a high value-added product. After being compounded and reinforced by long glass fiber at high temperature, it is widely used in interior and exterior trim parts of automobiles. Compared with the current general materials, It has high technical content, wide range of uses, and price advantage. It has turned to the direction of automotive functional materials and has a large market capacity.
YZSH has gradually solved the problems of high hydrogen concentration in the reactor, low production load, high polymerization temperature, difficulty in reaction heat removal, and inability to long-term production after many pilot productions of long glass fiber reinforced polypropylene special materials.
