Fluoraz® is formulated to work under the extreme pressures, temperatures and “sour fluids” found in deep well drilling. Fluoraz withstands high-pressure cycling. Because of Fluoraz’s low gas solubility, high modulus of elasticity and high shear tear strength, it resists rapid gas decompression. Fluoraz #790 is an Aramid fiber-filled compound specially formulated for downhole Vee Rings. Fluoraz #790 works well in high-pressure applications due to its relative hardness (65 Shore D).

Chemraz® is a member of the perfluoroelastomer polymer family—polymers of three or more monomers in which all hydrogen positions have been replaced with fluorine. This complete state of fluorination results in outstanding resistance to heat and most chemicals and solvents. The principle monomer of Chemraz is tetrafluoroethylene (TFE); the proprietary second and third perfluorinated monomers are unique to it and confer the balance of the properties it demonstrates. Chemraz’s resistance to steam and significantly improved low temperature properties are it’s hallmark. Chemraz—the ultimate elastomer for demanding oilfield applications—gives excellent sealing performance when exposed to mixes of aggressive chemicals found downhole and is often specified by operators. Special compounds have been formulated for improved resistance to rapid gas decompression and abrasion, giving significant reductions in downtime and maintenance.

Xyfluor® elastomers are highly fluorinated and combine excellent chemical compatibility with low-temperature capability. Performing in temperatures as low as -76°F (-60°C), Xyfluor resists aggressive media such as sour gasses and steam. In particular, it withstands H2S and CO2 better than comparable FKM and FQMV elastomers.

Greene, Tweed offers precision plastic components for a variety of demanding, semiconductor applications. These components are made from a full range of high-performance thermoplastic materials, including our Xycomp® composite materials. Xycomp is ideally suited to replace metal or ceramic compounds due to its high strength, low weight, corrosion resistance and dimensional stability. Xycomp materials may also be used in high-pressure and high-temperature (up to 250°C/482°F) applications. The optimal Xycomp material for a specific application is deter-mined by the unique combination of plastic material, fibers and fiber orientation, as well as manufacturing techniques. Greene, Tweed provides the necessary application evaluation services to assist in choosing the best performance characteristics.

Greene, Tweed offers precision-molded thermoplastic componentsmade from our high-performance Orthtek® composite materials fora variety of demanding medical and biotechnology applications.Orthtek WF components work well as metal replacements due toOrthtek’s high strength, low weight, corrosion resistance, anddimensional stability. Orthtek WF is recommended for applicationssuch as nail guides and retractors where radiolucentcy and auto-claving are required.

Greene, Tweed's Voraz™ 511, a perfluoroelastomer, combines good resistance to CVD and etch plasmas with low stiction to enhance process chamber efficiency and increase uptime in FPD and solar applications. Additionally, Greene, Tweed's proprietary (patent pending) Extenis® manufacturing process facilitates the creation of large seals such as those used in Gen 5+ slit valve doors and chamber lids. This unique combination of materials properties and design capability make Voraz 511 a highly engineered seal solution that is optimized to reduce the total cost of tool ownership for FPD and solar process equipment.
