Chemical Compatibility Chart

1 - 1 - PS247 Sept 08 Chemical Compatibility Chart The attached information has been prepared in good faith by RAPRA Technology Limited and other sources. Information should be used as a GUIDE only, as the information is only current at the date of publication. Chemical Compatibility cannot be read straight off charts, and other factors such as temperatures, concentration, pressure and duration of exposure can effect corrosion and distortion of materials listed.

2 NOTE: Totton Pumps use either: Rulon bearings, PTFE based compound Rulon can be regarded as chemically inert to most commercially used chemicals. However slight attack occurs with Acetic Acid, Nitric Acid, Ethylene Dibromide, Styrene, Bromine, Cyclo Hexane, Hexofluoro Propanol and Alkaline Metals. Graflon bearings, graphite filled PTFE Graflon is not suitable in: - Hydrogen fluoride gas, HF - Sodium Peroxide solution Na2O2 - Molten alkali metals - Acid nitric HNO3 - Acid mixed (nitric/sulphuric) HNO3 + H2SO4 - Acid, sulphuric 70% to 90% H2SO4 above ambient temperature - Acid, oleum H2SO4 (Nordhousen, fuming sulphuric) For further definitive information, we recommend contacting the Chemical supplier or at least testing samples under actual service conditions.
