NYCAST® 12

NYCAST® 12 offers very low moisture absorption, dimensional stability, superior wear resistance, and exceptional lubrication ability. NYCAST® 12 allows more precise machining and offers high impact strength.  It also offers better wear and creep resistance than standard nylon and also 20oF lower temperature capability than cast nylon 6.
