3M™ Dyneon™ Low Temperature Fluoroelastomer LTFE 6400Z

For years, design engineers have been challenged by a lack of high-performing elastomers for low temperature sealing applications. Especially in the automotive, aerospace and chemical processing industries, products with improved low temperature capabilities (-40°C) are needed.

Beginning of this century, Dyneon was the first company who developed a new class of low temperature fluoroelastomers, based on our 50 year experience in fluoroelastomer science.

3M™ Dyneon™ Fluoroelastomer LTFE 6400Z offers true low temperature sealing capability (TR10 & Tg = -40°C) while maintaining excellent fuel, oil, heat and permeation resistance. This unique combination of thermal and chemical resistance offer engineers the opportunity to simplify their designs, extend service life and cut costs.
