Why are car tires black?

Modern car tires come in a variety of sizes, patterns, materials and structures, but their colors seem to be very single, only black, why?

In fact, the world's first car tire is white, which is the primary color of rubber.

This kind of white tire is very difficult to use: not only is the tire strength and tear resistance not ideal, but it is also easy to age. After a long time, the rubber will turn yellow and brown.

Later, a company tried to make silver-gray tires from carbon black, and found that when carbon black was combined with rubber, it would make the rubber very strong. After repeated experiments,Black tires that are 10 times more wear resistant than white tires.

Rubber has good elasticity. Using rubber as a tire can reduce the bumpiness in driving. However, natural rubber wear-resistant, hot-melt, and grip have natural disadvantages. They cannot withstand friction and are easily worn out.

Black tires with carbon black can be well worn and anti-aging, and the life of the tire is extended by 10 times.However, Tires that are not blended with carbon black have a life of less than 8,000 km.

In addition to being more wear resistant, black tires are also resistant to UV rays and prevent tire cracking due to UV rays.

The car accident caused by tire failure accounts for a large proportion of car accidents, so the tire wear resistance and aging rate is an important indicator to distinguish the quality of the tire. Excellent tire wear resistance and aging resistance, can not be separated from the excellent wear-resistant tread formula design and high reinforcing performance of the reinforcing material to provide excellent wear resistance, cut resistance and tear resistance.
