Excellent performance characteristics of polyurethane elastomer:
We are a manufacturer mainly engaged in the research, development and production of castable polyurethane elastomer products. Because of the best comprehensive performance, the output of castable polyurethane accounts for more than 60% of it, and it is the most important variety of polyurethane elastomers with a wide range of applications.
1, The processing method is simple, convenient, easy to automate, and continuous production. In the production process of the cast polyurethane elastomer, the raw materials are all liquid, and they are measured, mixed, and reacted in the liquid state until they are poured into the mold, which is conducive to continuous mechanized production. In a sense, this advanced liquid processing is a "reform" of traditional rubber production methods.
2, Among the currently known elastomers, cast polyurethane elastomers have the best abrasion resistance. According to the laboratory measurement of its abrasion performance, it is 3-5 times that of ordinary natural rubber. If there is a certain amount of liquid wet abrasion, its abrasion resistance is even 10 times higher than that of ordinary rubber, so it is commonly called "resistant" Grind rubber".
3, The high wear resistance of cast polyurethane elastomer can not only be used as ordinary rubber for the manufacture of wear resistant parts, but also can replace traditional metal materials to a certain extent. Good wear resistance, cushioning, impact resistance, fatigue resistance, corrosion resistance, low noise and other properties are a supplement to traditional metals.
4, The castable polyurethane elastomer has a wide range of hardness changes (Shore A20-Shore D80), and it can still maintain good elasticity under high hardness. This is a performance that ordinary plastics and other materials are difficult to possess.
5, With excellent mechanical properties. The tensile strength of ordinary natural rubber, neoprene, etc. is generally lower than 30Mps, but the tensile strength of cast polyurethane elastomer is generally greater than 40Mps, and the tear resistance is generally much higher than that of ordinary rubber materials.
6, Excellent oil resistance. The oil resistance of polyester polyurethane is similar to that of nitrile nitrile rubber, which has the best oil resistance in traditional rubbers, but is better than natural, neoprene and other ordinary rubbers.
7, Excellent resistance to oxygen and ozone. According to the measurement of oxygen absorption volume of some rubber materials by Goodyear in the United States at 100°C for 160 hours, natural rubber 92mL/g; styrene butadiene rubber 18mL/g; polyurethane 0.64mL/g.
8, High compliance ability. The impact element in the preparation, the buffer element has a high bearing capacity and will not crack during use, while ordinary rubber has defects such as cracks under the load of high bearing capacity.

In 2021, despite the more complicated international situation, with the spillover of China's manufacturing capabilities and comprehensive national strength, the scale of my country's cross-border e-commerce will reach 1.98 trillion yuan, out of a high growth rate of 15%, and usher in a historical di
The electric sprayer has the advantages of simple structure, convenient operation, few failures, easy maintenance, low price, stable pressure, long operation time, wide application range and so on. There are many herbicide formulations, and different formulations have different formulation methods.
1. Unique impermeability:Rigid foam is a dense microcellular foam with a closed cell rate of more than 92% and a smooth self-skin. It is an excellent anti-seepage material.The rigid foam layer has no joints and is completely impermeable to water, which fundamentally eliminates the possibility of roo
Problems that should be paid attention to before and after use of polyurea spraying equipment:First of all, after spraying every day, or when changing the variety of spraying materials, the residual materials of spraying equipment and conveying pipelines should be removed, preferably once a day. The
As the name implies, with the rapid development of China's building energy saving market, polyurethane spraying equipment has been widely used in the field of building insulation and waterproofing, and the demand is increasing.
With the pace of green and civilized city construction, more and more attention is paid to the treatment and disinfection of domestic waste.1. The methods of garbage disposal, especially the methods of sorting and reusing garbage, have also appeared one after another, and gradually entered the ranks
Polyurea spray material is a new type of polymer material. Since this material has many different forms, and different forms of polyurea sprayers have many different characteristics, polyurea spray materials are widely used in contemporary society and industrial production.As the thermal insulation
