AIR WATER MACH Proprietary
High Performance Urethane Resin

Polyurea
  • Resin with excellent heat and abrasion resistance.
  • Withstands higher temperature (120°C) compared to normal urethane resin.
  • Resin with excellent roll edge abrasion resistance. Three to five times the abrasion resistance compared to ordinary urethane resin and 154 times compared to synthetic rubber.
  • Relatively easy to obtain from low hardness (JIS A80) to high hardness (Shore D78)
  • Used in practice in cold rolling lines and surface treatment lines (swing rolls, ringer rolls, tension bridal rolls, etc.) at steel manufacturers
