What impact does the fluidity of tire rubber have on its performance?

The flowability of tire rubber has a significant impact on its performance, mainly reflected in the following aspects:

1、 Processing performance

Mixing and extrusion: Tire rubber with good flowability is easier to mix evenly with various additives during the mixing process, improving mixing efficiency. Meanwhile, during the extrusion process, the flowable rubber material is more likely to pass through the mold, reducing extrusion resistance, improving extrusion rate and product quality.

Molding and vulcanization: Good flowability helps tire rubber to be better filled and molded in molds, reducing the generation of bubbles and defects. In addition, rubber materials with good fluidity are more likely to achieve uniform vulcanization during the vulcanization process, improving the overall performance of the tire.

2、 Physical performance

Hardness and elasticity: The flowability of tire rubber is closely related to its hardness and elasticity. Rubber materials with good fluidity often have better elasticity and flexibility after vulcanization, which helps tires to better absorb and disperse impact forces during driving.

Wear resistance: Tire rubber with good fluidity forms a more uniform cross-linked structure after vulcanization, which helps to improve the wear resistance of the tire. Tires with good wear resistance can extend their service life and reduce the frequency of replacement.

3、 Usage performance

Traction and braking performance: The fluidity of tire rubber also affects the traction and braking performance of tires. Rubber materials with good fluidity can provide better grip when the tire comes into contact with the ground, thereby improving the traction and braking performance of the tire.

Handling stability: Good fluidity helps the tire maintain stable handling performance during driving. Especially under extreme conditions such as high-speed driving and emergency braking, tires with good fluidity can provide better handling stability and safety.

4、 Other performance

Aging resistance: The flowability of tire rubber is also related to its aging resistance. The cross-linked structure formed by rubber materials with good fluidity after vulcanization is more stable, which helps to resist the erosion and aging effects of the external environment.

Environmental friendliness: In the production and use of tire rubber, materials with good flowability often reduce energy consumption and emissions, improve production efficiency and environmental performance.

In summary, the flowability of tire rubber has a significant impact on its processing performance, physical properties, usability, and other properties. Therefore, in the production and use of tire rubber, it is necessary to strictly control parameters such as flowability to ensure the overall performance and safety of the tire.
