Explanation:
Buna-N is a synthetic rubber made by polymerizing butadiene and acrylonitrile. It is widely used because of its excellent resistance to oil, fuel, and chemicals. Unlike natural rubber, Buna-N is manufactured artificially in industries to meet specific industrial needs. It is commonly used in making fuel hoses, seals, gaskets, gloves, and conveyor belts. Synthetic rubbers like Buna-N are important in modern industries because they are durable, flexible, and can withstand harsh environmental conditions better than many natural materials.
