Degussa AG Vestamid® X7163 High Viscosity, Heat Stabilized, Graphite Filled Nylon 12
Subcategory: Nylon; Nylon 12; Polymer; Thermoplastic
Material Notes:
Description: VESTAMID X7163 black is a graphite-filled and heat-stabilized compound for extrusion. Its improved properties of sliding friction make it most suitable for the production of push-pull cable liners. Further advantages of VESTAMID X7163black are the characteristic properties of PA 12like small water absorption, good dimensional stability and nearly constant mechanical properties at changing ambient humidity.
