Greene Tweed launches Fusion 665

Greene Tweed’s Fusion FKM 665 was specifically formulated to meet the requirements of AMS 7379 and AMS-P-83461. © 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°C to 232°C, Fusion 665 has been designed to achieve 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, Defence, 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).”

Greene Tweed is a leading manufacturer of high-performance thermoplastics, composites, seals, and engineered components. Combining more than 150 years of technical expertise and commercial knowledge in a variety of markets, Greene Tweed collaborates with customers to develop engineered solutions that meet challenging performance requirements and help reduce total cost of ownership.
