Greene Tweed
Fusion® 665
A New Generation, Ultra-Low-Temp, Chemical-Resistant Elastomer
Fusion® FKM 665, Greene Tweed’s ultra-low-temperature and chemical-resistant elastomer, is specifically formulated to meet and exceed the requirements of Aerospace Material Specification (AMS) 7379, 7410 and AMS-P-83461.
With its broad temperature range (-70°F to 450°F/-57°C to 232°C), Fusion® 665 performs well at low temperatures with zero leakage.
Fusion® 665 was developed by Greene Tweed to overcome existing limitations of comparable materials, such as those found in FKMs, NBRs, or FVMQs/Fluorosilicone, by offering the following benefits:
- Best-in-class high-temperature capabilities (450°F/232°C)
- Outstanding low-temperature sealing
- An extremely low compression set
- Broad chemical compatibility
- High-temperature sealing
