Esprix Ketoprix™ EKT33 (Natural) Thermoplastic Aliphatic Polyketone, High melt flow IM Grade
Categories:	Polymer; Thermoplastic; Polyketone
Material Notes:	Ketoprix™ EK33 and EKT33 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 moderate MF resins and are well suited for IM parts as well as the matrix polymer for moderately filled compounds. Ketoprix™ EK33 and EKT33 have excellent flow properties and are used in E&E, CAM, Auto and Industrial End Uses. Information provided by Esprix Technologies.
