What is the difference between nitrile and neoprene?

The main difference between nitrile (NBR) and neoprene is their resistance to oils and fuels. Nitrile offers superior resistance to hydrocarbons, making it ideal for automotive and petrochemical applications. Neoprene has better ozone and weather resistance but lower oil resistance. Choose nitrile if your application is in contact with oils, fuels, or solvents; choose neoprene if you need weather and ozone resistance.
