I got this question in final exam.
This question is from Insulating Materials topic in chapter Magnetic & Insulating Materials of Engineering Material & Metallurgy
To elaborate: Nitrile rubber is a copolymer formed by a combination of butadiene and acrylonitrile. It has good tensile strength and exceptional adhesion. It is largely used in aircraft fuel tanks, printing rollers, and O-rings.
