Characteristics:

  • Good corrosion resistance
  • Excellent polishability
  • Good wear resistance
  • Good machinability
  • Good dimensional stability during heat treatment

Major Application:

  • Corrosion/staining resistance : moulding of corrosive plastics, e.g. PVC, acetates, and for moulds subjected to humid working/storage conditions
  • Wear resistance : Moulding abrasive/ filled materials, including injection moulded thermosetting grades. S136 is recommended for moulds with long production runs, e,g, disposable cutlery and containers
  • High surface finish : production of optical parts, e.g. camera and sunglass lenses. Moulding of medical components, e.g. syringes and analysis vials
