The low-temperature and fatigue-resistant fastener system pads produced by BJGM Polymer Material Technology Group, a manufacturer of polyurethane shock-absorbing and energy-absorbing elastic pads, have passed the most important inspection by the Chinese railway department and have been tracked for a long period of one year Excellent performance in the test, the test results have been unanimously approved by industry experts;
At the same time, the company passed the supplier inspection of the industry's largest fastener system manufacturer and began certification by the Ministry of Railways. The company has also been certified and passed by the other two railway fastener system manufacturers, and will achieve supply.
In addition, other polyurethane elastic pads developed by the company in cooperation with the China Railway Technology Research Institute are underway at the same time, which can timely respond to new demands on future railway lines and firmly grasp the cutting-edge technology in the field of railway elastomer.
About BJGM Polymer Material Technology Group
BJGM Polymer Material Technology Group was established in 1999, mainly engaged in the research and development, production and sales of polyurethane materials. The company was listed on the Shenzhen Stock Exchange in 2011.
BJGM is currently the leading enterprise in China's high-performance composite polyurethane material industry, and the company is a "national high-tech enterprise".
The company has been focusing on the development and production of high-performance polyurethane shock-absorbing and energy-absorbing elastic pads. Its products include:
Polyurethane elastic pad
Microporous polyurethane elastomer composite material, product cell structure is uniform and fine, closed cell structure is more than 95%. Material characteristics: low dynamic and static stiffness ratio, small compression set, excellent fatigue resistance and weather resistance. Finished product use: mainly used for the production of elastic pads under the iron pads of WJ-8 fastener system for high-speed rail passengers.
Polyurethane elastic pad
Pouring polyurethane elastomer composite material, this product is a non-foaming product, the material moisture content is less than 0.01%. Material characteristics: high mechanical strength, excellent wear resistance, low permanent deformation, excellent fatigue resistance and weather resistance. Finished product use: mainly used for the production of elastic pads under the iron pads of WJ-12 fastener system for heavy-load railways.
Underlay of polyurethane rail
Microporous polyurethane elastomer composite material, product cell structure is uniform and fine, closed cell structure is more than 95%. Material characteristics: low dynamic and static stiffness ratio, small compression set, excellent fatigue resistance and weather resistance. Finished product use: mainly used for the production of high-speed rail passenger special WJ-8 type fastener system iron pad under the elastic pad
Rubber pad under turnout board
Product Description As a form of train speed change and change, turnouts have increasingly higher requirements on vibration damping performance during the period when a large number of trains pass through, the whole track bed is widely used, and the train speeds up. In the urban rail system, the noise passing by the turnout area is also harmful to the environment. At different positions of the turnout, the static stiffness of the backing plate is all different to keep the static stiffness of the joints of the track consistent and meet the requirements of vibration and noise reduction. Material characteristics: low dynamic and static stiffness ratio, small compression set, excellent fatigue resistance and weather resistance.
Tram damping pad
Modern trams have the advantages of light weight, fast speed, low investment (one-kilometer tram investment is only one-third of the underground railway), environmental protection and no pollution. They are gradually starting to invest in construction in medium and large cities. The trains shuttled in the city have high requirements on vibration absorption and noise reduction performance. The materials produced by our company have low dynamic-static ratio and good resilience, which can meet the requirements of city vibration reduction. Material characteristics: low dynamic and static stiffness ratio, small compression set, excellent fatigue resistance and weather resistance.
Other castable polyurethane elastomer compound
Polyether polyurethane prepolymer, which can be expanded with MOCA or BDO, has a full range of products, hardness from 50A to 98A, and a wide range of use. The advantages of its products are high mechanical strength, excellent wear resistance, oil resistance, acid resistance and chemical solvent resistance. Finished product use: It can be used to produce various polyurethane elastomer products, such as rubber rollers, rollers, rubber plates, seals, etc.
Products are widely used in important industries or fields such as packaging, printing, transportation, safety protection, household appliances, and building materials.
The company has established a technical R & D team of more than 60 R & D personnel led by 4 Ph.D. Organize technical research and product development. The products developed by the company have been listed as national torch plan projects, national key new products and key technology innovation projects many times.
