NYLENE 743HS
TECHNICAL DATA SHEET

 
General Description    

  • Heat stabilized, high impact modified nylon suitable for both molding and extrusion.
  • In addition to heat stabilization to prevent thermal degradation, parts molded from 743HS have excellent R.T. and C.T. impact strength right out of the mold without post conditioning.
  • Outstanding features of Nylene 743HS include high strength and high cold temperature impact.
  • Cylinder temperatures should be in the 435 - 525°F range.
