ARAMIDE Aramide Low strength, mainly used in high temperatures applications. STEEL CORD Steel cord Extremely high strength, dimensional stability and corrosion resistance due to brass coating. 06.13.0108
06.13 SLANGER TABELLER/TEKNISK OG KLEMMER INFORMASJON TUTER Kjemikalietabell (Reprinted from RMA Hose Handbook IP-2, fourth edition) The kinds of materials being handled by flexible rubber hose, are constantly increasing in number and diversity. To assist in the selection of the proper elastomer for the service conditions encountered, the following table has been prepared. The reader is cautioned, that is only a guide, and should not be used as such, as the degree of resistance of an elastomer with a particular fluid depends upon such variables as temperature, concentration, pressure, velocity of flow, duration of exposure, aeriation, stability of the fluid etc. Also variations in elastomer types and special compounding of stocks to meet specific service conditions have conciderable influence on the result obtained. Table of chemical, oil and solvent resistance of hose When in doubt, it is always advisable to test the tube compound under actual service conditions. If this is not practical, tests should be devised, that simulate service conditions, or the hose manufacturer contacted for recommendations. The following table list only the more commonly used materials, chemicals, solvents, oil etc. The recommendations are based on room temperature and pressure conditions normally recommended for the particular type of hose being used. Where conditions beyond this can be met readily, they have been so indicated, where conditions are not normal, and cannot be readily met, the hose manufacturer should always be consulted. The table does not imply conformance to the Food and Drug Administration requirements of Federal or State Laws when handling food products. 06 WARNING: The following data has been compiled from generally available sources and should not be relied upon without consulting and following the hose manufacturer´s specific chemical recommendations. Neglecting to do so might result in failure of the hose to fulfill its intended purpose, and may result in possible damage to property and serious bodily injury.
