Poly amid chips
Nylon 6.6 Chips
We produce nylon 66 chips from best quality nylon salt, which by going through two-stage poly condensation process is transferred to high viscosity polyamide 66 chips. Our production line is equipped with most modern and advanced DCS control system, which has the characters of technology process complication and high autoimmunization to ensure us about our high quality chips.
Nylon 66 chips are especially suited to application for tire cord yarn.
