How Nitrile Gloves Are Made
Nitrile gloves are a popular choice among healthcare professionals, as well as those in food service and other industries, due to their durability and resistance to chemicals. But how are these gloves made?
The process of making nitrile gloves begins with the production of nitrile rubber, also known as acrylonitrile-butadiene rubber (NBR). Nitrile rubber is made by polymerizing a mixture of acrylonitrile and butadiene, which are both synthetic compounds. The resulting rubber is then cut into small pieces and sent to the glove manufacturing facility.
Once at the facility, the nitrile rubber is mixed with other ingredients, such as pigments, fillers, and lubricants. This mixture is then fed into a machine called an extruder, which melts and homogenizes the ingredients. The melted mixture is then forced through a small opening, known as a die, to create a thin sheet of nitrile rubber.
Next, the sheet of nitrile rubber is cooled and cut into small strips, which are then rolled into a cylinder shape. These cylinders are then fed into a machine called a calendar, which flattens and smooths the rubber strips.
After the nitrile rubber has been flattened and smoothed, it is cut into the shape of gloves using a machine called a cutter. The gloves are then inspected for defects and any gloves that do not meet quality standards are discarded.
The final step in the process is to package the gloves. Nitrile gloves are typically packaged in boxes of 100 or more, and are often sterilized using ethylene oxide or gamma radiation before being shipped to customers.
It's important to note that Nitrile gloves can be made in different thicknesses, colors and textures depending on the application they are intended for. The thinner the gloves, the more dexterity and sensitivity the user will have but less durability. On the other hand, thicker gloves offer more protection but less dexterity. Similarly, powdered gloves are easier to put on but can cause irritation or allergies to some people, on the other hand, powder-free gloves are more expensive but safer for sensitive skin.
In conclusion, nitrile gloves are made from nitrile rubber, which is produced by polymerizing a mixture of acrylonitrile and butadiene. The rubber is then mixed with other ingredients, extruded, cooled, cut, flattened, shaped and packaged. The final product can be customized according to thickness, color and texture, depending on the intended use. Nitrile gloves offer a great combination of durability and chemical resistance, making them a popular choice in various industries.
