Acrylonitrile-Butadiene Rubber (NBR) vulcanizates and metals, put into contact with each other for a long period under pressure, develop an adhesion force between them. We call this phenomenon 'fixing' and define the bond strength as the fixing strength. Fixing can be very dangerous, because it often takes place in a part of sensors for the fuel systems of cars and in gas-seeping alarms of home gas ranges. A similar phenomenon has been known to occur between rubber hoses and metal tubes, although it is not as dangerous. Little attention has been paid to elucidating the mechanism of fixing and its prevention. The purpose of this paper is to study various factors influencing fixing and to propose some methods for it's prevention.
