Esprix Ketoprix™ EK23 (Natural) Thermoplastic Aliphatic Polyketone, Ultra High melt flow IM Grade
Categories:	Polymer; Thermoplastic; Polyketone
Material Notes:	Ketoprix™ EK23 resins are thermoplastic aliphatic polyketones containing a 1,4-diketone backbone structure, produced from ethylene, propylene and CO with perfectly alternating olefin and CO monomers in the backbone. These natural resins are very low viscosity resins, ideal as the matrix polymer for highly filled compounds. Excellent flow properties and the basis for our highly filled Flame Retardant, Conductive and High Strength Fiber grades. Easily colored. Information provided by Esprix Technologies.
