Greene Tweed

Greene Tweed announced the availability of its Arlon 3000 XT thermoplastic for extreme conditions in oil and gas applications, providing better mechanical analysis. It demonstrates a glass transition temperature 35° F higher than PEEK, and provided superior mechanical property retention from 350° F to 600° F. The material provides improved volume resistivity 30 times that of PEK at 400° F (204° C) and dielectric strength, measured at 730 V/mil using a 40-mil-thick sample in an ASTM D149 testing. In addition, Arlon 3000 XT 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 (200° C to 260° C), which provides the support typically provided by a metal element.
