Nitrile gloves are made of a synthetic material. They contain no latex proteins and offer excellent resistance to punctures and tears. Nitrile gloves are three times more puncture resistant than rubber and can be used to offer superior resistance to many types of chemicals. Unlike latex gloves, nitrile gloves have low resistance to friction and are very easy to slide on. There are a few other reasons that nitrile gloves are more popular than latex or vinyl gloves, including a higher degree of flexibility and superior solvent resistance.
