Nitrile rubber (NBR) is also called Nitrile-butadiene rubber. Unlike many other types of rubber, nitrile is resistant to oil, fuel and a whole list of other chemicals. Nitrile is an incredibly strong material, but has a lower degree of flexibility, which is why holes are less likely to occur. Likewise, there is less risk of developing allergens when using nitrile.
NATURAL RUBBER/LATEX
Latex is also often referred to as natural rubber, as it comes from the trees. The material is incredibly elastic, which is why it is often used in e.g. work gloves. In addition, it protects against many acids and bases and has a relatively good temperature resistance. Latex is also extremely waterproof.
