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 extractable are an orde of magnitude lower than premium competitive FKM formulations, ensuring little or no contamination into the process stream. Fluoraz 890 also meets the extrative requirements of both 21 CFR 177.2600 (e), (f) and 21 CFR 177.240 (d) extraction testing for perfluoroelastomers. Fluoraz 890 sanitary gaskets by Greene, Tweed are designed for minimal intrusion.Fluoraz 784 is also available in O-rings and custom shapes where a low durometer hardness is desired.

Sanitary gaskets made from Fluoraz® 799 proivde a level of performance in SIP and CIP systems that surpasses all other elastomers. While EPDMs and FKMs can provide a seal for extended periods, chnages 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 installation specifications, the gasket will be compressed at a greater level than desired, resulting in increased intrusion into the proecess stream. An increased in hardness/modulus and a drop in elongation means embrittlement. The seal will be undertorques, resulting in either leaks or cracking.

Xyfluor® 860, a highly fluorinated elastomer compound, offers excellent chemical compatibility over a wide range of temperatures from -76°F to 450°F (-60°C to 232°C). Recommended for applications requiring a combination of low temperature properties and chemical resistance, Xyfluor's capabilities surpass those of standard fluoroelastomers, PTFE and graphite. Addtionally, Xyfluor reduces overall cost by extending equipment service life.

Fluoraz FEPM 797 is a Perfluoroethylene Propylene Copolymer (FEP) product. It is available in North America.

Protection against oxygen-infused plasma is key in many etch chamber environments. These harsh environments often breakdown non-resistant materials, causing harmful particulation and, ultimately, defective chips.Greene, Tweed's Chemraz® XPE is highly resistant to O2 plasma and can be used in a wide range of applications, such as slit valve doors, reaction chamber lid seals, and gate valve seals. This advanced elastomeric material offers the semiconductor and solar industry an alternative to legacy products that quickly erode in the oxygen environment. With excellent resistance to both 02 and CF4 plasmas, this material affords an increased chip yield and maximized production. In addition, XPE seals provide customers with an increased MTBR (mean time between repair) to reduce downtime and maintenance costs.

Greene FKM 731 is a Fluoroelastomer product. It is available in North America.

Sanitary gasket made from Fluoraz® 784 work well in SIP and CIP applications where a low durometer elastomer compound is needed. While EPDMs and FKMs can provide a seal for extended periods, change 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 ot the installation specification, th 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 784 is formulated for use in sanitary gaskets and other applications where low sealing force is required, such as sealing sight glasses or as a seal between nonmetal parts. Fluoraz 784 is FDA and USP Class VI compliant, making it a versatile compound for both pharmaceautical and other hygienic fluid handling applications. Fluoraz 784 metal and TOC extractables are an order of magnitude lower than premium competitive FKM formulations, ensuring little or not contamination into the process stream. Fluoraz 784 cna be used as a sanitary gasket in standard applications as long as the torque used to install the gasket is minimal (hand tight).Fluoraz 784 is alos available in O-rings and custom shapes where a low durometer hardness is desired.
