Ultra-low-temperature FKM exceeds requirements
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 -57 to +232°C, Fusion 665 achieves 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).”
