Greene Tweed has launched Arlon 3000 XT, a new thermoplastic for extreme conditions in oil and gas applications.
In dynamic mechanical analysis it demonstrated a glass transition temperature 35°F higher than PEEK, and provided superior mechanical property retention from 350°F to 600°F. In extrusion testing, it outperformed both virgin and filled grades of PEEK and PEKEKK.
Arlon 3000 XT provides improved volume resistivity 30 times that of PEK at 400°F and dielectric strength, measured at 730 V/mil using a 40 mm thick sample in ASTM D149 testing. In addition, it has 1.5 to 6 times higher mechanical properties compared to PEEK in tensile, compressive, flexural and shear tests at a test range of 392°F to 500°F, which provides the support typically provided by a metal element.
It is capable of withstanding all common oilfield chemistries, and is appropriate for use in back-up rings, v-rings, electrical connectors and seal assemblies.
