Nitrile gloves are a type of disposable glove made of synthetic rubber. They contain no latex proteins and offer excellent resistance to wear and tears. Nitrile gloves are more puncture resistant than many other types of rubber gloves and can be used to offer superior resistance to many types of chemicals. They are often considered to be one of the the strongest types of disposable glove and are generally safe for people who are allergic to latex.
Unlike other disposable gloves, nitrile gloves have low resistance to friction and are very easy to slide on. As with some other types of disposable gloves, however, powder such as cornstarch may be added in order to make putting on the gloves as easy as possible. Nitrile gloves come in a variety of sizes to fit all hands, from extra small to extra large. They can be made in a variety of textures, cuff lengths and thickness.
These gloves are popular for their high degree of flexibility and superior solvent resistance. They are resistant to many oils and some acids, making nitrile gloves a good choice for many manufacturing environments. Nitrile gloves should not be stored under excessive light or heat, however, as that can make the rubber disintegrate more rapidly.
When choosing a glove, individuals should consider how much protection they need, the glove's quality and how it is made, and whether the wearer has any allergic reactions to the glove's material. Nitrile gloves offer less dexterity than latex gloves, so they aren't the best choice in all situations; the lower level usually isn't a concern for tasks that do not require very fine finger dexterity. They are often recommended for people with a latex allergy.
In the manufacturing process of latex, vinyl, and nitrile gloves, there are standard measurements applied to the gloves. In order to rate the protective qualities of the glove, they are graded from 1 to 3. The glove that receives a medical grade means that it has received the highest protection rating. These gloves are rigorously tested to pass US Food and Drug Administration (FDA) requirements.
The next grade is the high-risk category. These are used in the emergency medical service fields, such as by paramedics. A very high level of testing is required in order to assure the proper requirements are reached.
The next level is the utility grade. These are not intended to be used in the medical field and they are not tested to any FDA specifications. These gloves are recommended for jobs that require hand protection, however, such as painting. The American Society for Testing and Materials (ASTM) regulates the standards of utility grade gloves.
