Greene Tweed invented ultrahigh and low temperature resistant (-57 ° C to 232 °

Greene Tweed’s Fusion FKM 665, a new generation, ultra-low-temperature and chemical-resistant elastomer, was specifically formulated to meet and exceed the requirements of Aerospace Material Specification (AMS) 7379 and AMS-P-83461.



With a temperature range of -70°F to 450°F (-57°C to 232°C), Fusion 665 achieves outstanding low-temperature performance without compromising high-temperature performance.

“Prior to Greene Tweed’s Fusion 665, elastomer material composition resulted in trade-offs,” said Wally Hajduczek, sealing systems product manager for aerospace, defense, and life sciences. “Achieving optimal low-temp performance meant sacrificing high-temperature operating range, chemical compatibility, or dynamic sealing performance. Fusion 665 was developed to overcome existing limitations of comparable materials, such as NBR, FKM, or FVMQ (Fluorosilicone).”
