THERMIZOL – 1 is a highly efficient insulating backfill for insulating liquid material in large sprues and in vats. Due to its chemical and physical parameters it is one of the best materials of this type – both technically and economically. THERMIZOL’s low bulk density makes it more efficient: 1 tonne of the backfill might replace 4 to 5 tonnes of standard, Lunkieryt type backfill.
