The main material of industrial tires is rubber, which can be divided into natural rubber and synthetic rubber. Natural rubber has good elasticity and aging resistance, but it is more expensive and may not be as durable as synthetic rubber in some special environments. Synthetic rubber has stronger oil resistance and high temperature resistance, and is suitable for oily or high temperature working environments, but its elasticity may be slightly inferior to natural rubber.
In addition, industrial tires can also use other materials, such as polyurethane, which has wear resistance and tear resistance, suitable for use in harsh working environments, but the cost may be higher.
In rubber formulas, commonly used inorganic fillers include carbon black, white carbon black, calcium carbonate and montmorillonite. These fillers can not only improve the strength and wear resistance of rubber, but also improve processing performance and extend service life. For example, carbon black can improve the strength and wear resistance of products; white carbon black can improve the hardness of rubber; calcium carbonate and montmorillonite can enhance the reinforcement and tear strength of rubber.
