Greene FKM 938 is a Fluoroelastomer product. It is available in North America.

WR® 525 is a thermoplastics composite consisting of carbon fiber in a PEEK™ matrix. WR provides excellent chemical resistance, non-galling and nonseizing properties, impact resistance and thermal shock and hydrolysis resistance.WR 525 allows the pump user to increase pump efficiency by running tighter wear rings clearances while decreasing potential pump damage when pumos are cavitated or experience down-line bearing failures.

Chemraz E38 is a Perfluoroelastomer product. It is available in North America. Typical application: Sealing Applications.Characteristics include: Chemical Resistant Heat Resistant High Purity

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.

Greene, Tweed's Chemraz® 526, a perfluoroelastomer, offers superior chemical compatibility coupled with rapid gas decompression (also known as explosive decompression) resistance, making it the ideal compound for fluid handling equipment exposed to extreme chemical environments. Chemraz 526 has a temperature range from -4°F to 482°F (-20°C to 250°C). With its outstanding RGD (rapid gas decompression) resistant capabilities, Chemraz 526 is well suited in a range of applications from pumps and valves to oilfield completion equipment.Chemraz 526 is available for use as O-rings, gaskets and many other custom shapes.

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.

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.

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.

Greene, Tweed offers precision-molded thermoplastic components made from our high-performance Orthtek® composite materials for a variety of demanding medical and biotechnology applications. Orthtek WF compnents work well as metal replacement, and dimensional stability. Orthtek WF is recommended applications such as nail guides and retractors where radiolucentcy and autoclaving are required.
