Polyurethane /Polyurethane Rollers /PU rubber roller


Polyurethane rubber has a wide range of hardness, as low as low modulus rubber below Shore A10, and high impact elastic material as high as Shore D85. Its elastic modulus can be as high as hundreds of megapascals, which greatly exceeds others. The elastic modulus of rubber is in the range (approximately 0.2-10 MPa), so polyurethane rubber has a wide range of properties and is a type of polymer material ranging from rubber to plastic. It is also precisely because of polyurethane's outstanding characteristics of wear resistance, oil resistance, aging resistance, low temperature resistance, high hardness, and high elasticity. In recent years, the amount of polyurethane has increased rapidly, and the scope of application has continued to expand. It is widely used in petrochemical, mining machinery, and light industry. Machinery, water conservancy engineering, transportation and shoemaking, papermaking, electromechanical and other industries have replaced and saved a large amount of wood, steel and various rare metals. However, the existing polyurethane rubber rollers are not ideal for use in some special environments. Especially when used for a long time and under high speed conditions, its high temperature resistance, friction resistance, and corrosion resistance performance will be significantly reduced. For example, the polyurethane parts used in foreign high-speed cigarette equipment imported from our country have to run for a long time under the condition of high speed, and the wear of the parts is more serious. The use time is only 20 to 35 days, which not only affects production efficiency, but also has zero The components are all imported, so the running cost is higher

The purpose of the present invention is to provide a polyurethane rubber roller with superior performance in terms of wear resistance, corrosion resistance and high temperature resistance.

Compared with the prior art, the present invention has the following advantages and effects. By adopting the above scheme, the formulated polyurethane product has extraordinary wear resistance, high temperature resistance, corrosion resistance, aging resistance and other properties, and its wear resistance is natural rubber The comprehensive performance of its products is 10 times that of rubber products, and the price is only 1-2 times that of general rubber, especially the polyurethane rubber roller formulated with the above formula, in the working environment of high speed and spraying industrial glycerin , There is no change after three months of use. However, the existing ordinary polyurethane rubber rollers cannot be used due to foaming or severe abrasion in less than one month. Its comprehensive performance is also superior to similar foreign products, and the cost is low. It is an ideal product that can completely replace imports.
