| Chemical (Fluid, Gas) Compatibility: Buna-n (Nitrile Rubber) | |||||
| Commercial Buna-N (Nitrile) rubber compounds are generally attacked by the following list of over 200 chemicals, normally exhibiting severe effect on the physical properties of the rubber and, therefore, are normally unsuitable for either dynamic or static seals and gaskets in environments containing them. | |||||
