How does silicone tubing behave with acids, bases, and oils?

Silicone performs well against water, dilute acids and bases, alcohols, salt solutions, and vegetable or animal oils. It also handles high-boiling mineral oils reasonably well over short periods. Where it performs poorly is with aromatic hydrocarbons (benzene, toluene, xylene), ketones (acetone, MEK), esters (ethyl acetate), certain chlorinated solvents, concentrated mineral acids and strong alkalis, and low-molecular-weight petroleum fuels such as gasoline and diesel. Contact with these media causes swelling, softening, and loss of tensile strength. For applications involving petroleum-based fluids or aggressive organic solvents, fluorosilicone (FVMQ) is the appropriate material choice. Regardless of the fluid, it is good practice to verify compatibility against a detailed chemical resistance chart and conduct immersion testing under actual operating conditions.
