Urethane tends to have a higher load-bearing capacity, greater tear strength, better compression set, and greater abrasion resistance than rubber. It is also more tolerant of greases, oils, and ozone. Rubber bushings tend to deteriorate rapidly with age. As rubber bushings become softer and more pliable, they resist...

2.1 "Automatic loading vehicle field 2.1.1 "Rolling resistance The chemical composition of polyurethane material determines that it has a lower rolling resistance than rubber. Lower rolling resistance will improve the efficiency of electric automatic loading vehicles and reduce the number of...

The earliest polyurethane wheels were solid wheels, which showed the advantages of excellent wear resistance and large carrying capacity when transporting goods under harsh conditions, and are still widely used today. Beginning in the 1970s and 1980s, some domestic and foreign wheel companies or R&D...
