The EPDM material widely used in the food industry shows indeed the best performance in CIP processes here, but is not usable in every product containing fat. While FKM and VMQ materials are indeed resistant to fat-containing media, they have only limited resistance in the cleaning media customarily available on the market. Fluoroprene® XP was designed specifically for the high demands of the food industry and thus also the dairy industry. It is a 3-A® Sanitary Standards Class I mate- rial and can therefore also be used in pure olive oil and in butter with a fat content of 82%. In addition, the material is recommended not only for use in diluted, but also in con- centrated CIP/SIP media. Fluoroprene® XP is a very highly-fluorinated material with a specific monomer composition. As a result of this, the performance almost achieves the capability of a perfluo- roelastomer. General properties • Excellent temperature resistance up to +200 °C (+392 °F) • Very good resistance to ozone, weathering, aging and oxygen • Excellent resistance in mineral oils and fats • Low gas permeability • Very good resistance in non-polar media such as hexane • Tends to increased swelling in polar solvents (e.g. ethylene- diamine) and ketones (e.g. methyl-ethyl-ketone) Application profile Seals made of Fluoroprene® XP are characterized by an excellent and broad resistance. The blue Fluoroprene® XP material thus allows the replacement of EPDM, VMQ and FKM in applications with foodstuffs and pharmaceuticals, as it combines the excellent properties of EPDM materials in polar media (water, acid, alkaline solution) with the ex- cellent performance characteristics of FKM and VMQ types in all non-polar media (fats, oils and hydrocarbons). Its outstanding resistance in steam, hot water, alkaline solu- tions and acids as well as in non-polar solvents makes it the preferred elastomer for applications with extreme CIP/SIP cleaning media, high temperatures and fat concentrations. Thanks to Fluoroprene® XP, the multiplicity of materials can thus be reduced significantly, which minimizes the com- plexity and cost of storage and maintenance of plant and equipment on a lasting basis.
