3M Dyneon™ 2299X Ultra High Viscosity Fluoroelastomer (discontinued **)
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	3M™ Dyneon™ FC 2299X is an ultra high viscosity fluoroelastomers designed for use in applications such as o-rings, gaskets and seals requiring higher strength than achievable with lower viscosity fluoroelastomer copolymers. When appropriately formulated, FC 2299X provides higher tensile strength, improved tear resistance, and lower compression set than comparably formulated, lower viscosity fluoroelastomer copolymers. These products are offered in either slab form (FC 2299X) or in free flowing granule form (FC 2299PX). Features and Benefits: Ultra high viscosity gumstock without incorporated curatives Copolymer composition of vinylidene fluoride and hexafluoropropylene Targeted for compression molding Both are diamine or dihydroxy curable gums Available in easy-to-weigh granular form Information provided by the Dyneon division of 3M.
