What is Styrene Butadiene Rubber (SBR)?
Styrene Butadiene Rubber (SBR) is widely preferred in many industries today and also called as the world’s only synthetic rubber. SBR, as the chemical substance, is a mixture of approximately 75% butadiene and 25% styrene.
Styrene-butadiene rubber, which is a general purpose synthetic rubber type, is used much more than other synthetic rubbers. It is used in the production of tires for the trucks and automobile by replacing rubber which is resistant to abrasion.
Most of the synthetic rubbers produced worldwide are made of styrene-butadiene rubber. Styrene-butadiene rubber, which contains 23% styrene, becomes harder as this ratio increases and the high resistance to low temperature diminishes.
Styrene-butadiene rubber, similar to natural rubber, has high ozone and atmospheric durability. The temperature range of the styrene-butadiene rubber varies between 50 and 110 °C. The styrene-butadiene rubber, which is irregular in its structure, provides an economic advantage because the rubber is inexpensive.
Styrene Butadiene Rubber Advantages and Uses
The most important advantages that increase the use of styrene butadiene rubber are the economic advantage and durability. In addition, the styrene-butadiene rubber is extremely resistant to bases, glycol-based brake fluids, and alcohol. The basic uses of styrene butadiene rubber, which also prevents crystallization, are as follows:
- Production of automobile tires
- Shoe manufacturing
- Washbasin seals
- Electric industry
- Sports equipment
- Washing machine rolls
