1. General information and introduction41.1IntroductionWhen dealing with aggressive fluidsthe user is continuously faced with theproblem of finding compatible materials.In order to simplify the selection ofsuitable materials when using Bürkertproducts for aggressive fluids, thefollowing tables provide useful informationon the optimal choice ofhousing and gasket materials for amultitude of media.Since corrosion performance is influencedby several factors, the informationcontained in this brochure should betreated only as a guide and is notnecessarily valid for all operating conditions.Increased temperatures, higher concentrations,and the inadvertent ingressof water in originally pure chemicalscan all lead to accelerated corrosion.Dependent on the purity of the fluid aswell as the compounding and natureof vulcanisation of the gasket materials,deviations can result which affect thesuitability and durability of the plasticsand elastomers.The information quoted in this guidedoes not consider the effect ofmechanical loading, which may alsohave a bearing on the material performancein the fluid. In cases ofdoubt when considering our products,we strongly recommend the prior testingof samples with various materialcombinations, in order to establishand check their suitability under theactual operating conditions of theapplication.Where liquid food products areinvolved, the plastics and elastomersemployed must normally conform withthe local food and hygiene regulations.It is emphasized that these resistancetables are intended only as a guideand that no guarantees can be givenin respect of the information containedin this publication.1.2Structure and contentof the chemicalresistance chartsThe following chemical resistance tablesare divided into three categories. Theseare basic chemicals (chapter 2.2),commercial products (chapter 2.3)and liquid food and beveragesingredients (chapter 2.4).The resistance of these fluids is ratedin detail for the elastomeric materials,plastics and metallic materials commonlyemployed in Bürkert products.Rarely used materials such as CSMas well as aluminum are not describedin the tables. Epoxy resin, which iscommonly used in the construction ofour products, but which is not mentioned,is resistant to most common chemicals.Information regarding the chemicalresistance of the unlisted materials isavailable on request, including chromeand nickel-plated parts. Please see theoverview in chapter 2.1 for additionalinformation regarding general chemicalresistance of seal and body materials.For the most commonly used chemicalsubstances the chemical formula isadded in the charts.The suffix "pure" means the technicalpureness of the fluid, which in mostcases exceeds 95% purity. As a rule,organic fluidic or gaseous media havethis supplement. "Acetic acid - pure"means for example a 98% acetic acid.

The suffix "aqueous" is mostly usedfor water miscible substances (suchas Ethanol) but also for aqueous solutionsof inorganic salts. Due to thegreat number of possible concentrations,an average concentration isalways assumed.Saturated aqueous solutions aredescribed only if explicitly noted andthe reference temperature for allstatements is room temperature.At higher temperatures a reducedchemical resistance must beconsidered.1.3Interpretation ofSymbols+ material is not affected or is slightlyaffected by the chemical: suitable$ various attack level depending onprevailing conditions: limitedsuitability– material exhibits severe attack:unsuitableIf materials are rated as "limited suitability",the time of impact has to beconsidered. At a long period of impactthese materials can be heavily attackedor even destroyed. Therefore theseparts are rated as wear parts and arenot included in the standard warrantyconditions.1.4ReferencesAll the information quoted in theseresistance tables is based on industrialexperience (for example "DECHEMA -Werkstoff-Tabelle", Germany or"DECHEMA Corrosion Handbook"),the data of our material and compoundmanufacturers and Bürkert's ownstringent laboratory tests.In many cases it is not possible tomake a clear statement due to differentservice conditions. In these cases therating should also be "limited suitability".5
