Butadiene does not have a direct use in seal applications, but thanks to its resistance to wear and abrasion it is used for the production of pneumatics and transmission systems such as belts and conveyor belts. It is also used as a component for the production of special compounds with properties of resistance to abrasion and ageing, and flexibility at low temperatures.

The Elastotech code for this compound is: ME14XX/YY.
