There are many types of protective gloves, such as the familiar disposable pe gloves, latex gloves, medical examination gloves and nitrile gloves. Among these protective gloves, nitrile gloves should be relatively unfamiliar to everyone. So what exactly is nitrile?
What is nitrile
Disposable latex gloves are made of natural rubber. Unlike nitrile gloves, they are synthetic. Nitrile is an abbreviation for acrylonitrile-butadiene rubber. This material is the product of the polymerization of monomers acrylonitrile and butadiene.
Nitrile gloves come in a variety of colors, which helps to distinguish management processes and prevent cross-contamination. For example, blue means medium size, indigo blue means large size, or blue for poultry and green for vegetables.
When did nitrile gloves start to appear
Nitrile gloves were widely used as a synthetic rubber in 1991. The German Bayer first developed synthetic rubber. In 1909, it successfully synthesized rubber polyisoprene. However, due to the high cost, the supply and demand of natural rubber was balanced. It has not been really used by people. After the outbreak of the First World War, there was a shortage of natural rubber and the price rose, leading more countries to embark on the road of synthetic rubber research and development. In 1931, Germany was the first to synthesize nitrile, and it was put into mass production in Germany and the United States.
Features of nitrile gloves
1. Outstanding chemical resistance, resistance to certain acids and alkalis, and good chemical protection against corrosive substances such as solvents and petroleum.
2. Good physical properties, good tear resistance, puncture resistance and friction resistance.
3. The style is comfortable, and the glove machine designed according to ergonomics makes it comfortable to wear and facilitates blood circulation.
4. It does not contain protein, amino compounds and other harmful substances, and rarely causes allergies.
5. Low surface chemical residue, low ion content, small particle content, suitable for strict clean room environment.
Industries where nitrile gloves are suitable
1. Laboratory personnel: The nitrile gloves are comfortable and comfortable, have stable performance, and have excellent chemical resistance. They can avoid the irritation and damage of chemical substances to the skin. It is an excellent choice for laboratory personnel.
2. Assembly line workers: workers who face hazardous chemicals, such as those who work in battery manufacturing and processing plants, face the hazard of lead and need to wear gloves at work. Nitrile gloves are the best choice in this case, because nitrile is produced from synthetic rubber that has excellent chemical resistance. In addition, nitrile gloves are more comfortable to wear, and the gloves will fit better when exposed to body temperature, thus providing better operating sensitivity.
3. Catering industry: Nitrile gloves are comfortable to hand and suitable for long-term wear. They are ideal choices for food processing and food service fields. Of course, PVC and PE gloves are alternate choices, but they are only suitable for light and short-term operations.
4. Maintenance workers: Maintenance workers usually come into contact with grease, oil and other solvents when servicing machinery and vehicles. Use disposable nitrile gloves to protect their hands.
5. Cleaning workers: These workers need to wear gloves to protect themselves from chemicals in cleaning supplies and to protect themselves from pathogens when cleaning the bathroom. Because nitrile gloves can resist harmful chemicals, nitrile is often used by such workers.
