Follow basic safety practices to minimize risk when working with hazardous chemicals.
Higher temperatures increase the effect of chemicals on industrial rubber hose compounds. The increase varies with the polymer and the chemical. A compound quite suitable at room temperature might fail very quickly at higher temperatures.
A rubber hose compound usually swells when exposed to a chemical. With a given percent fo swell, a hose tube may function satisfactorily if the industrial hose is in a static condition, but fail quickly if the hose is subject to flexing.
Basic rubber polymers are sometimes mixed or blended together to enhance a particular property for a specific service. The reaction to a particular chemical blend of polymers may, therefore, somewhat different from the reaction to the single ones. When in doubt, a sample of the compound should always be tested with the particular chemical it is to handle.
