Polyurethane encapsulated elastomer has large bearing capacity, wear resistance and oil resistance, and is firmly bonded to the metal frame. It can be used to manufacture rubber wheels, guide wheels, and pulleys for cable cars that are widely used in various transmission mechanisms. The roller is a steel wheel with external polyurethane. The steel wheel needs to be carefully processed, sandblasted, cleaned, and brushed with adhesive. These steps are simple. Why do many manufacturers do degumming? When brushing the adhesive, it is dry for the first time and brushing again. The temperature control of the steel wheel before pouring is required. The temperature is best to be close to the temperature of the polyurethane material during pouring. Many of the details of the operation need to be experienced. The polyether cannot be used as a roller. Many manufacturers only know to make money and choose cheap polyether. It should be noted that the molecular structure and cross-linking of polyether cannot meet the requirements of heavy load.
Polyurethane encapsulation also has the characteristics of oil resistance, good toughness, and strong adhesion. It is very common to use on vehicles such as monorail cranes, rack cranes and cleaning vehicles for mining, and the effect is relatively ideal! Various tires have been developed in China using the characteristics of polyurethane's high strength and high hardness. Polyurethane elastomer is suitable for manufacturing low-speed, heavy-duty vehicle tires.
