Nitrile is a synthetic acrylonitrile and butadiene polymer. Nitrile gloves were made for the growing group of people who developed allergies to latex gloves. However, nitrile has more advantages than being made of synthetic rubber, which is not an allergen. Nitrile gloves are durable. The nitrile glove is 3 times more puncture-resistant than latex or vinyl. After improved production processes, the characteristics of nitrile gloves can be closely compared to their latex counterparts in terms of comfortability, elasticity (elongation limit 500%), and adaptability to hand shape. Nitrile gloves are widely used in machine repair shops and households with direct contact with lubricants, automotive petrol or other chemicals. Nitrile gloves are suitable for use at high temperatures; however, they should be stored at low temperatures in a dry and dark place. Nitrile is not as "sticky" as latex, and most people do not have problems putting on and removing gloves. However, nitrile is not as elastic as latex. Therefore, it is imperative to choose the correct glove size.
