What are the application characteristics of tire rubber in different types of tires?

The application characteristics of tire rubber in different types of tires are mainly reflected in the following aspects:

1、 Basic characteristics of tire rubber

Tire rubber usually refers to silicone used for precision mold casting and manufacturing of tires. This type of silicone generally uses condensation type room temperature vulcanized silicone as the basic raw material. It has the characteristics of good fluidity, low shrinkage rate, good tensile strength, good operability, good chemical stability, good fire resistance, and no pollution. These characteristics make tire rubber widely applicable in tire manufacturing.

2、 Application of tire rubber in radial tires

Radial tires, also known as steel wire tires, have good wear resistance, puncture resistance, cushioning performance, stability, safety performance, low driving temperature, and high driving mileage. Tire rubber powder has different application characteristics in different parts of radial tires:

Tread driving surface:

The tread driving surface refers to the adhesive layer above the bottom of the tread pattern groove and in normal contact with the ground, requiring good wear resistance, puncture resistance, and grip performance.

Tire rubber powder can be used as an additive to improve the wear resistance of the tread surface while reducing costs.

Tire body:

The tire body, also known as the tire body, is mostly composed of a single layer of steel cord fabric, which gives the tire sufficient strength to withstand the load and vibration during driving.

An appropriate amount of fine tire rubber powder can be added to the tire body rubber to reduce costs.

Shoulder:

The shoulder is the transition layer between the crown and sidewall of the tire, requiring good thermal conductivity to avoid shoulder clearance caused by high temperatures.

Waste tire rubber powder can be appropriately mixed into the shoulder rubber material to reduce raw material costs.

Tire Beads:

The tire bead is mainly composed of steel wire rings, upper and lower triangular rubber cores, steel wire wrapping cloth, and sub mouth protective rubber.

Waste tire rubber powder can be added appropriately to components such as bead core wrap and triangular rubber core to enhance their strength and stability.

Tire sidewall:

Tire sidewall rubber refers to the adhesive layer on the outer curtain layer of the tire sidewall, which serves to prevent mechanical damage, atmospheric effects, and moisture from affecting the tire body.

More tire rubber powder can be added to the sidewall rubber to improve its flexural flexibility and aging resistance.

3、 Application of tire rubber in silicone rubber tires

Silicone rubber tires, also known as tire silicone or tire silicone, are synthetic rubber with better biological and environmental properties than ordinary rubber. It has the characteristics of good elasticity, friction resistance, no pollution, strong drainage, and high grip and rolling resistance. These characteristics make silicone rubber tires have broad application prospects in special fields such as high-end automobiles, racing cars, electric vehicles, etc.

4、 Other applications of tire rubber in tire manufacturing

In addition to the above applications, tire rubber can also be used for the manufacturing of tire molds. Due to its good fluidity, low shrinkage rate, and good tensile strength, tire rubber is very suitable for manufacturing tire molds. This type of mold can ensure the accuracy and quality of tires, and improve the production efficiency of tires.

In summary, the application characteristics of tire rubber in different types of tires are mainly reflected in improving wear resistance, reducing costs, enhancing strength and stability. With the continuous advancement of technology and the continuous development of the tire industry, the application fields of tire rubber will become more extensive.
