The history and properties of black tires http://www.kanatarimsandtires.ca Initially rubber tires came in a white color, since it’s the color that rubber naturally occurs in. In the beginning of the 20th century, Smith&Binneystarted selling their carbon black chemicals to leading tire manufacturing companies, as it was discovered that carbon black when used in rubber manufacturing highly increased some good qualities of rubber used to make tires. Uses of Carbon Black Carbon black is used as reinforcing filler for rubber, and increases the strength and durability of rubber. In actual figures, when you add 25% by weight carbon black it increases the road tear abrasion of the produced tire by around50 folds and increases the tensile strength by roughly504%. Tensile strength is the amount of force required to pull something to its bursting point or breaking limit.
By adding carbon black, heat conduction is greatly improved aiding in the transfer of heat from some hot points of the tires; especially, in the belt and traders, as they are very likely to overheat during driving. Heat conduction minimized thermal damage to the tire and greatly increases its life span which is a very desirable factor when buying Ottawa
Winter Tires.
From a beauty point of view, black tires are a preferred choice for many due to the ease in cleaning and also maintaining them clean which when compared to white is a true challenge. On their part white tires may be used as a show of elegance in luxury vehicles. In the early days when black tires like Ottawa Winter Tires were not very common, they were associated with only strong vehicles though. Carbon black is nearly pure elemental carbon in particle form. It is traditionally made by charring organic material. Industrial Carbon black used today is typically produced as Thermal Black orFurnaceBlack. Furnace Black is made using oils with a heavy aroma. Thermal Black is made using natural gases, usually methane, which is injected into a hot furnace, in the absence of sufficientair;hydrogenand carbon black are the end products. Key Facts

Instead of using carbon black for shoe making, the common additive used is fumed silica, it has same reinforcing characteristics of carbon black, but the rubber remains white. The disadvantage of using additives with silica base on tires is that they have a bad wear properties than tires made with a carbon black base. However, silica based tires give better handling on wet surfaces together with a lower rolling loss like Winter Tires Ottawa, this increases fuel efficiency greatly. For these reasons, there are tires currently being made with silica-based additives though they are very rare as of now.

Carbon black is not the same as activated carbon or soot though they are close. Carbon black has a high surface area to volume ratio than soot.
