Material

SLS PK

SLS PK is a tough, ductile polyketone with excellent chemical and fuel resistance, very low moisture absorption, and low friction and wear, suited to functional parts exposed to fluids, though it is somewhat less stiff than PA12.

About

SLS PK (polyketone) is a tough engineering thermoplastic with excellent chemical resistance, high barrier properties against fuel and water, and very low moisture absorption, so humidity barely affects its properties or dimensions. It also has low friction and better wear behavior than polyamides, but it is somewhat less stiff, denser, and less ductile across the layers than PA12.

SLS PK is well suited to under-the-hood automotive parts, fluid-handling components, and wear-prone sliding parts.
