Black nitrile gloves are nitrile gloves which have been colored with a black dye. There are also black latex gloves, which look very similar to nitrile gloves but are manufactured from latex, a material which will trigger allergies.
The color isn’t the only thing about black nitrile gloves which stands out. These gloves tend to be tougher and more durable, and while they are not sterile, they are usually thick enough to keep bacteria and viruses from penetrating the glove, which makes them safe for use in biohazardous situations. Black nitrile gloves also do not show stains, which can make them less distracting.
Black nitrile gloves are not powdered. Many companies texture their gloves to provide additional grip and traction. The lack of powder can make the gloves a bit more difficult to put on. It is important to draw the gloves on carefully so that they don’t tear or rupture, thereby compromising their ability to protect the hand. Powder-free gloves will also not leave stains and marks which is a definite benefit in the eyes of some users.
Automotive mechanics, beauticians, and other people with somewhat messy jobs use black nitrile gloves to reduce visible stains as well, making it easier for them to focus and see what they are doing.
