NYCAST® GX (Gray) is a solid lubricant filled nylon 6. NYCAST® GX was developed after years of research as an alternative to other “solid lubricated” cast nylons. GX gives engineers another superior choice from the NYCAST® family of premium grade cast nylons.
NYCAST® GX is specially formulated, self-lubricating grades designed to:
