MODUK - DTD-5595A
Vulcanized Butadiene - Acrylonitrile Rubbers (Fuel and Synthetic Oil Resistant)
The materials covered by this specification are intended for the production of items such as sheets, moldings and certain extrusions, mainly for sealing applications in contact with petroleum-based fuels and diester based lubricants. They are generally suitable for use within the range - 40°C to 120°C for continuous operation and for certain selected applications may be considered for use up to 150°C for short intermittent periods. They are unsuitable for use in contact with phosphate ester hydraulic fluids and have poor ozone resistance.
NOTE. At ordinary temperatures and in the absence of hostile environments, eg when properly stored, these rubbers deteriorate only very slowly. However, the rate of deterioration increases markedly with increased temperature and the service life of a rubber therefore depends upon the operational temperature. Conversely, the maximum temperature at which a rubber may be used depends upon the useful life required.
