What are the special requirements for tire rubber in bicycle tires?

There are some special requirements for tire rubber in bicycle tires, which mainly stem from considerations such as the usage scenarios, performance requirements, and environmental protection of bicycles. The following is a detailed analysis of these special requirements:

1、 Requirements for raw materials and ingredients

Combination of natural rubber and synthetic rubber:

Bicycle tire tread rubber typically requires good wear resistance, fatigue resistance, aging resistance, as well as high elasticity, tensile strength, and toughness. Therefore, it is often processed with natural rubber or natural rubber combined with styrene butadiene rubber and butadiene rubber.

Application of recycled rubber:

In order to reduce costs, latex reclaimed rubber or tire reclaimed rubber is also used in the manufacturing of bicycle tires. These recycled rubbers have good compatibility with natural rubber and synthetic rubber, and can be mixed in appropriate proportions into bicycle tires, effectively reducing raw material costs while ensuring product quality.

Latex reclaimed rubber is processed from natural rubber waste cups, waste latex gloves, waste condoms and other raw materials, possessing the basic properties of natural rubber, high strength, good elasticity, and excellent wear resistance.

Tire reclaimed rubber is processed from waste tires and mainly consists of natural rubber, universal synthetic rubber, and carbon black. It has good compatibility with natural rubber, butadiene rubber, and styrene butadiene rubber.

2、 Performance characteristics requirements

Wear resistance and aging resistance:

Bicycle tires need to withstand friction and wear during the riding process, so tire rubber must have good wear resistance.

At the same time, tire rubber also needs to have excellent aging resistance to extend the service life of tires.

Elasticity and tensile strength:

Bicycle tires need to maintain a certain degree of elasticity and tensile strength to cope with various impacts and vibrations during cycling.

This helps maintain the stability and comfort of the bicycle, improving the riding experience.

Puncture resistance and tear resistance:

Bicycle tires may encounter sharp objects during cycling, so tire rubber needs to have high puncture resistance and tear resistance.

This helps prevent tires from being punctured or torn, improving cycling safety.

3、 Color and environmental requirements

Color diversification:

With the increasing demand for personalized bicycle appearance from consumers, the colors of bicycle tires are becoming increasingly diverse.

The color of tire rubber needs to match the overall color of the bicycle to meet the aesthetic needs of consumers.

Therefore, in actual production, it is necessary to choose the appropriate latex reclaimed rubber or tire reclaimed rubber according to the color of bicycle tires.

Environmental performance:

The recycling of tire rubber helps to reduce the pollution of waste tires to the environment and achieve the recycling of resources.

Meanwhile, with the increasing awareness of environmental protection, more and more bicycle tire manufacturers are starting to use environmentally friendly materials to replace traditional tire rubber.

These environmentally friendly materials have lower volatile organic compound (VOC) emissions and better biodegradability.

4、 Requirements for different parts

tyre:

The outer tire tread rubber needs to have good wear resistance, tear resistance, and puncture resistance.

The sidewall rubber needs to have excellent flexural flexibility and aging resistance.

In actual production, suitable latex reclaimed rubber or tire reclaimed rubber can be selected for blending according to the color and performance requirements of the outer tire.

Inner tube:

The inner tube needs to have good airtightness and elasticity.

In actual production, latex recycled rubber or tire recycled rubber can be used to replace some natural rubber in the production of inner tubes to reduce production costs.

At the same time, it is necessary to ensure that the airtightness and safety of the inner tube are not affected.

In summary, there are some special requirements for tire rubber in bicycle tires, which mainly stem from considerations of bicycle usage scenarios, performance requirements, and environmental protection. In actual production, it is necessary to select suitable tire rubber according to these special requirements to ensure that the quality and performance of bicycle tires meet the needs of consumers.
