Material Notes:
Sanitary gaskets made from Fluoraz® 890 are ideal for use in standard SIP and CIP applications where EPDMs and FKMs fail. While EDPMs and FKMs can provide a deal for extended periods, changes in physical properties can have adverse effects beyond simple volume swell. A decrease in hardness or drop in modulus signals a reduction in compressive strength. If a sanitary gasket is retorqued to the installations specification, the gasket will be compressed at a greater level than desired, resulting in increased intrusion into the process stream. An increase in hardness/modulus and a drop in elongation means embrittlement. The seal will be undertorqued, resulting in either leaks or cracking.Fluoraz 890 is formulated for use in sanitary gaskets where both USP and FDA compliance is required, making it an excellent compound for both pharmaceutical and other hygienic fluid handling applications such as seals for brewery applications. Fluoraz 890 metal and TOC extractables are an order of magnitude lower than premium competitive FKM formulations, ensuring little or no contamination into the process stream. Fluoraz 890 also meets the extractive requirements of both 21 CFR 177.2600 (e), (f) and 21 CFR 177.2400 (d) extraction testing for perfluoroelastomers. Fluoraz 890 sanitary gaskets by Greene Tweed are designed for minimal intrusion.Fluoraz 890 is also available in O-rings and custom shapes where a medium durometer hardness is desired.Information provided by Greene Tweed.
