Typical application

ARKAL 60 PR V is dedicated to complex and large shape for glass contact application such as :

  • forehearth channel blocks,
  • day-tank blocks,
  • flow blocks, skimmer and flow blocks,
  • spout lip sub paving, restrictor and wetback tiles.

 

ARKAL 60 PR V properties are also adapted to the expendable applications like mandrels for Danner tubing process.
