There are five types of nitrile rubber (NBR) in terms of its acrylonitrile content and mooney values. They are cold NBR, hot NBR, cross linked hot NBR, carboxylated nitrile(XNBR), and bound antioxidant NBR. Regarding for cold NBR, the current generation of cold NBR’s spans a wide variety of compositions. Acrylonitrile content ranges from 15% to [...]

There are two primary criteria to defining each specific NBR grade. One is Acrylonitrile content and the other is mooney viscosity and polymer architecture. Regarding for Acrylonitrile content, it is one of two primary criteria defining each specific NBR grade. The ACN level, by reason of polarity, determines several basic properties, such as oil and [...]
With more and more governmental environmental protection awareness, the related laws and regulations by local administration have become more and more rigorous and law enforcement more severe. In the meanwhile, traditional manufacturers in China have started to launch green production program since the beginning of the 21st century. Until now, almost ten years has been [...]
