EK23, EKT23 (Natural)
PRODUCT CHARACTERISTICS
Ketoprix™ EK23 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 very low viscosity resins and are ideal as the matrix polymer for highly filled compounds. Ketoprix™ EK23 has excellent flow properties and forms the basis for our highly filled Flame Retardant, Conductive and High Strength Fiber grades. Ketoprix™ EK23 Is easily colored.

PROCESSING
KETOPRIX™ Polyketone resins are processable in conventional Injection Molding (IM) equipment. Much more information about IM operation of KETOPRIX™ Polyketone resins is contained in our KETOPRIX™ Injection Molding Guide. The key to processing KETOPRIX™ Polyketones is to minimize holdup and residence time as much as possible. Additional thermal stability is available with the EKT resins that contain added thermal stabilizers and antioxidants.
ENVIRONMENTAL, HEALTH & SAFETY
KETOPRIX™ Polyketone resins are not hazardous. For information on handling and storage of KETOPRIX™ Polyketone resins, please consult our Safety Data Sheets, available from Esprix Technologies.
For more detailed information, please contact your representative at Esprix Technologies.
REGULATORY
KETOPRIX™ Polyketone resins comply with all regulatory statues in the USA.
