With many engineering resins now in short supply and prices increasing there is no better time to be looking for material alternatives. Polyketone is a semi-crystalline polymer that combines: the higher heat performance of polyamide 6 and 6/6, the fuel resistance of nylon 11 and 12, the low moisture absorption of PBT, and the exceptional wear & friction performance of POM. When it comes to injection molding, polyketone holds a significant benefit over traditional materials such as nylons, acetal, and polyester for cycle time, ease of drying, no off-gassing, and no need to rely on moisture for toughness. Polyketone exhibits similar mold shrinkage to these resins allowing for existing molds to be used.
