Esprix Ketoprix™ EKT63 (Natural) Thermoplastic Aliphatic Polyketone, Low melt flow IM Grade
Categories:	Polymer; Thermoplastic; Polyketone
Material Notes:	Ketoprix™ EK63 and EKT63 resins are thermoplastic aliphatic polyketones containing a 1,4-diketone backbone structure. They are produced from ethylene, propylene and CO with perfectly alternating olefin and CO monomers in the backbone. These natural resins are low MF IM resins and are well suited for IM parts and lightly filled compounds. Ketoprix™ EK63 and EKT63 have excellent flow properties and are used in E&E, CAM, Auto and Industrial End Uses. These resins can also be used in small diameter pipe & profile extrusion applications.
