What is Rubber?
Rubber is a durable, flexible material obtained from rubber tree, which has a great place in today's industry. The rubber used in shoes, raincoats, buttons, combs and belts used in our daily lives is also widely used in car tires. The rubber tree takes its name from ‘kauçi gelen which means weeping tree in the language of the Indians. The locals see a white, sticky, milk-like liquid flowing through the tree, drying it over time and making toy balls. After many years, rubber is also used in Europe.
High elasticity is one of the most important properties of rubber. The rubber softens when heated and melts at 220 ° C. Rubber oil is then obtained by distillation, which is used as the solvent of the rubber. Rubber, also known as pure rubber, is due to the fact that the tire obtained from the rubber tree is 90% pure. At the same time rubber is not a conductor for electric current and is therefore widely used in areas such as insulation.
How is rubber produced?

The sap of the rubber tree is called latex. To collect latex, V-shaped crevices open with iron blades on the tree trunk. If the collected latex is left to itself, the rubber beads coagulate. Rubber can be produced by coagulating latex. Acids such as acetic acid and formic acid are used. Approximately 35% of the latex obtained here is rubber.

In order to become a rubber, it has to be mixed with chemicals such as sulfur, and rubbers carrying 12-20% sulfur are called tires. If the sulfur content is high, a product called ebonite is used as an electrical insulator. The method of introducing chemicals such as sulfur to cure rubber is called vulcanization, which enables the strengthening of chemical bonds at high temperatures.
As the use of rubber has entered all sectors, the demand for rubber has increased, resulting in a shortage of rubber. Then this situation shaped the construction of artificial rubber. Synthetically produced rubbers use butadiene compounds. Unlike natural rubber, it is more heat resistant and does not wear easily.
