Since 2000 , The company has been engaged in the research of engineering plastics and engineering applications , and is the main production base of nylon modified materials for rail fasteners in China.
The application of the company's modified composite materials in rail transit can be mainly divided into two directions: line fastening system,vehicles and locomotives, which have achieved several successful applications and developed a series of typical products both at home and abroad.
The company developed the high-strength toughened nylon material, which solved the problems of cold resistance and aging resistance in the plateau area, and was fist successfully applied to Qinghai-Tibet Railway; The company also developed the glass fiber reinforced PA66 composite material, which solved the problems of high strength and high toughness and reinforced fatigue resistance, and was successfully applied to the first heavy-duty freight line in China. The reaction injection molding wear-resistant nylon developed has solved the problems of strength and wear resistance, and has been successfully applied to wear core discs, bogies and bushings and other high-strength wear-resistant parts.
By simulating the changes of rail transit materials and products under various extreme conditions of outdoor (such as high temperature, high humidity, dryness, cold, high irradiation, ozone, salt spray and hot and cold alternation,etc) the company has formed a series of reinforced nylon products and toughened nylon products to meet the domestic and foreign various working conditions in the rail transportation industry. The products can meet the requirements of various lines such as high-speed lines, heavy-duty lines, mixed passenger and cargo lines, urban railways and subways as well as ordinary railroads; while serving the market demand of domestic high-speed railways, the products are exported to the United States, Europe, Australia, Africa, Central Asia and Southeast Asia and other countries and regions.
Through systematic research and development, we select high-quality raw materials, adopt advanced manufacturing process, and also add nano-materials for modification to significantly improve the performance of paint film hardness, anti-scratch, corrosion resistance and other properties.. It provides high performance protection for the inside and outside of high speed railways, locomotives, subways and other vehicles in the field of rail transportation, as well as for motors, electrical accessories of rail transportation and vibration-damping plates. while serving the market demand of domestic high-speed railways, the products are exported to the United States, Europe, Australia, Africa, Central Asia and Southeast Asia and other countries and regions.
