Do you know the polyurethane composition used to fill tires?
1, Introduction to Polyurethane Components
Polyurethane is a polymer material composed of compounds such as isocyanates, polyethers, and polyesters, commonly used to fill tires. Isocyanates are the main component of polyurethane materials, and commonly used isocyanates include dimethyl phenyldiisocyanate, polytetrahydrofuran diisocyanate, etc. Polyether and polyester are relatively auxiliary components.

2, Characteristics of Polyurethane
1. Wear resistance: Polyurethane filled tires have good wear resistance, low friction coefficient, and long service life.
2. Elasticity: Polyurethane has good elasticity, which can effectively alleviate ground vibrations and ensure driving stability.
3. Durability: Polyurethane filled tires are not subject to external wear and tear, and there will be no air leakage during use.
4. High temperature resistance: Polyurethane filled tires have good high temperature resistance, can withstand high temperatures and instantaneous high temperatures, will not harden or adhere due to temperature rise, and have a longer service life.
5. Explosion resistance: Polyurethane filled tires can effectively prevent tire blowouts and ensure the safety of vehicle operation.
3, Application scope of polyurethane
Polyurethane filled tires are widely used in industrial, agricultural, and transportation vehicles. It is used in agricultural vehicles such as tractors, combine harvesters, and sprinkler irrigation machines; Mainly used in industry for electric forklifts, material handling and transportation equipment, etc; In the field of transportation, it is mainly used for excavators, bulldozers, cranes, and construction vehicles.
4, Polyurethane safety issues
Although polyurethane is an effective ingredient in filling tires, safety issues still need to be taken into consideration. To ensure safe use, it is necessary to use polyurethane materials produced by reputable tire manufacturers and follow the manufacturer's instructions for use and maintenance to avoid unnecessary hazards.
In short, polyurethane is a very important component in filling tires, with excellent characteristics such as wear resistance, elasticity, firmness, high temperature resistance, and explosion resistance. Its widespread application provides a reliable guarantee for vehicle transportation.
