“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).”
