CHEMICAL RECOMMENDATIONS

The 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 it is only a guide and should 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, aeration, stability of the fluid, etc. Also variations in elastomer types and special compounding of stocks to meet specific service conditions have considerable influence on the results obtained. 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 condtions or the hose manufacturer contacted for Recommendations.

The following table lists the more commonly used materials, chemicals, solvents, oils, etc. The recommendation 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 & Drug Administration requirements of Federal or State Laws when handling food products.

TABLE OF CHEMICAL, OIL AND SOLVENT RESISTANCE OF HOSE
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.

Resistance Rating
A Good Resistance, usually suitable for service. IR Isoprene, synthetic EPDM Ethylene-propylene-dieneterpolymer
F Fair Resistance, the chemical has some deteriorative effects, but the elastomer is still adequate for mod- erate service. SBR Styrene-butadiene MQ Dimethyl-polysiloxane
C Depends on Condition, moderate service may be possible if chemical exposure is limited or infrequent. CR Chloroprene FKM Fluoracarbon rubber
X Not recommended, unsuitable for Service, NBR Nitrile-butadiene CM Chloro-polyethylene
I Insufficient Information, not enough data available at the time of publication to determine rating. IIR Isobutene-isoprene ECO/CO Ephichlorohydrin
NR Natural Rubber CSM Chloro-sulfonyl-polyethylene EXLPE Cross-linked polyethylene
