The main cause of yellowing of nitrile gloves
Recently, customers in the dust-free industry called to consult our Xinchen electronic nitrile glove manufacturer: nitrile gloves may turn yellow during use and storage. What is the cause of the yellowing of nitrile gloves? Can the yellowed nitrile gloves continue to be used normally?
The main cause of yellowing of nitrile gloves
We know that acrylonitrile (AN) is one of the main polymerized monomers for the production of polymer materials such as nitrile rubber gloves. The quality of acrylonitrile directly affects the performance of subsequent processed products, and acrylonitrile has the highest oxazole content. The key is that it not only affects the color and storage stability of acrylonitrile, but also affects the color of the polymer material after synthesis. Relevant test data show that the oxazole content in acrylonitrile exceeding 75mg/kg may cause some chemical reactions of acrylonitrile. In other words, if the acrylonitrile oxazole content in the gloves exceeds the standard, the gloves will turn yellow. First, there is a problem with the color of the finished product. Second, the color will change after a period of storage. And improper maintenance and storage methods lead to premature aging.
That is to say, the high probability of yellowing of nitrile gloves is due to aging or quality problems. In this case, nitrile gloves are of poor quality and easily break. If used in the medical, food, chemical, and electronic industries, it is not recommended to continue to use. It will affect the quality of use and cause unnecessary trouble. If it is at home, if it is not troublesome housework or no need to touch sharp objects, the gloves can still be used if they are not damaged. But be careful, if the nitrile glove is broken, it is easy to scratch your fingers.
