The diversity of pu castor processing, make the applicability of the polyurethane elastomer is very extensive, application domain expands unceasingly. Oil resistance, ozone resistance, aging resistance, radiation resistance, good low temperature resistance, good acoustic, stick relay is strong, good biological compatibility and blood compatibility. These advantages is polyurethane elastomer in military industry, aerospace, acoustics, and biology extensively in the fields of application. Pu castor how to meet the unique requirements of different users? Superior wear resistance. In the presence of water, oil and other wetting medium work conditions, the wear resistance of polyurethane casters are often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but doesn't have to wear; Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, stadium track the runway, forklift truck crane dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Pu castor manufacturers a number of physical and mechanical performance indexes can be adjusted through the selection of raw materials and formulations, flexible changes within a certain scope, so as to meet the unique requirements of users on the product performance. Such as hardness, is often the user an important index of products, polyurethane elastomer can be made into Shao Er A hardness of the 20 or so soft printing rubber roller, and can be made more than 70 Shao Er D rigidity rolling roller, this is the general elastomer material is difficult to do, can suit the needs of different users. Polyurethane elastomer is composed of many flexible chain segment and rigid chain segments of the polarity of polymer materials, with the improvement of rigid chain segment ratio and the increase of density of polar group, elastomer original strength and hardness will be increased accordingly. Also can be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting molding ( The CPU) ; Can also be made from grain, like common plastic, use process such as injection, extrusion, calendering, blow molding, The CPU) 。 Mold or injection molding parts, within a certain range of hardness, cutting, grinding, drilling and other mechanical processing. High elastic polyurethane casters need to mention here is that to improve the low and middle hardness, the friction coefficient of polyurethane elastomer parts, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of polyurethane elastomer aluminum and graphite or silicone oil lubricant. Processing methods diversity, wide applicability. Polyurethane elastomer can be the same as general rubber plastication, mixing and vulcanization process molding ( The MPU) ; ( )
