C are manufactured in PSR-333. This is the same refractory composition as used for feeder expendable refractories and has shown itself to be a proven performer for long forehearth life in more than a thousand forehearths installed to date. Its low thermal conductivity inhibits corrosion at the channel joints and the absence of glassy phase eliminates it as a source of ‘cat-scratch’ cord.

  • PSR-333 is the internationally renowned feeder expendable refractory material that combines long service life with excellent thermal shock properties.
  • PSR-993 is also offered as an alternative material for Channel blocks and Spout bowls.
