Material Notes:
3M™ Dyneon™ Low Temperature Fluoroelastomers LTFE 6400Z are technically advanced low temperature, peroxide-cured fluoroelastomers, designated as a FKM type 3 elastomer per ASTM D1418. They are designed to meet the challenging demands of the automotive, aerospace and chemical processing industries, requiring low temperature sealing in chemically aggressive environments. LTFE 6400Z offer a unique low temperature sealing capability of TR10 = -40°C as well as broad chemical resistance.Features and Benefits:TR10 = -40°C which means true dynamic sealing capability at low temperaturesVery good chemical resistance against most chemicals such as acids, bases, fuels, oils, coolants, and alcoholsProcesses comparably to other peroxide-cured fluoroelastomersGood compression set resistance with low/no post-cureInformation provided by the Dyneon division of 3M.
