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.
