Asked by ayushi pandey | 17 Jul, 2014, 10:18: PM
Expert Answer
Buna-N is obtained by copolymerization of 1, 3-butadiene and acrylonitrile.
Acrylonitrile is responsible for resistance to petro, lubricating oil and organic solvents. Nitrile is the most widely used elastomer in the seal industry.
It has excellent resistance to petroleum products , good physical properties and is superior to most rubbers in regards to compression set, tear and abrasion resistance.
