PrimeCast 101- Polystyrene

Product information
PrimeCast 101, a grey powder on polystyrene basis, is suited especially for investment casting due to its excellent dimensional accuracy and its low melting point.

  • high dimensional accuracy
  • low residual ash-content
  • very high surface quality
  • good strength for use as lost pattern


  • patterns for investment casting
  • master patterns for vacuum casting, herby it is advised to infiltrate the parts with e.g. epoxy resin
