Technical Information

What is Rubber?

Rubber is a flexible substance produced from the sap (latex) of some tropical plants or from petroleum and natural gas. The one produced from the sap of trees is called natural rubber, and the one produced from petroleum products is called synthetic rubber. Both types are versatile substances. Items made of rubber are generally referred to as tyres.

Rubber is a durable, flexible material obtained from rubber tree, which has a great place in today’s industry. The rubber tree gets its name from ‘kauchi’, which means weeping tree in the Indian language. Seeing that a white, sticky and milky liquid was flowing from the tree, the locals dried it over time and started to make toy balls.

Over 15 million tons of rubber are produced annually all over the world; about a third of this is natural rubber. Due to the demand for natural rubber, synthetic rubber was obtained by the Germans in the 1900s in order to obtain cheap and abundant rubber, and thus many types of rubber emerged. When natural rubber is repeatedly stretched many times, it almost returns to its original dimensions. This feature distinguishes rubber from synthetic rubber and all other materials containing substances such as rubber.

Rubber, which is found in products such as shoes, raincoats, buttons, combs and belts that we use in our daily lives, is also widely used in car tires. It is a very important product due to its softness, durability, adhesiveness, water and air tightness, and it is used extensively in areas such as insulation and isolation as it does not conduct electricity.

Today, rubber is used as widely as wood and these advantages make this material perfect for tire production, largely due to its beneficial properties such as strength, longevity, water resistance and heat resistance. In fact, a large percentage of rubber production is in the automotive industry. Rubber comes in a wide variety of colors, styles, and textures and is extremely diverse.

How Is Rubber Formed?

The rubbery sap of the plant is called “latex”. Since latex is found in the inner part of the bark, the bark is slit in a V shape and the liquid is poured out. The resulting liquid is then taken into a shallow bowl and formic acid is added. Latex coagulates after 10-30 minutes. The coagulated latex becomes an elastic dough. Then rolling is done between the two rollers to allow excess water to be expelled.

After rolling, it is rinsed and dried on hangers in order to completely remove the formic acid. The latex that waits here for about 5 hours dries and gains a harder and stronger structure. It also darkens in color. After this process, the product is thoroughly cleaned by entering the brush washers.

The product, which is then taken to the shelves, is kept in brick ovens for 45 days in smoke. The reason for keeping it in the smoke is to prevent mold formation during this period. The rubber obtained at the end of 45 days is divided into classes, stacked on top of each other as leaves, pressed in order to occupy less space, and taken to warehouses.

Material Properties

The milky white liquid in the bark of the rubber tree is called “Latex”. Rubber is obtained from 30-40% of the collected liquid. Since natural rubber has a regular structure, its physical properties are positively affected. Another important feature of natural rubber is its smoothing under load and tension. Due to this feature, the breaking strength values ​​increase even if there is no reinforcing filler in its structure.

The operating temperature is between -60°C and 90°C.

Physical Properties:

High breaking strength
High tear strength
High raw rubber strength
High elasticity values
High dynamic values
High permanent deformation values

Usage Environment:

Aqueous environments with low temperatures
Glycol based oils

Usage Area:

Mechanical parts
Vibration and shock damping parts
Horoscope
Vibration damping connections
Engine parts
Shoe Sole
Hoses
Conveyor belts
Floor covering
Sponge
Adhesives
