Basic Information

HTIW products are:

  • Made of synthetic vitreous and polycrystalline mineral wools
  • Defined by a classification temperature above 1000 °C
  • Typically used at temperatures above 600 °C
  • Necessary for many high-tech products owing to their versatile characteristics
  • Essential for minimizing energy consumption and correlated greenhouse gas emissions

MMMF overview

HTIWs are produced synthetically from mineral raw materials. There are some important differences between natural fibres and Man Made Mineral Fibres. Beside the differences in the chemical composition, MMMF have parallel edges.

However, as their name suggests, HTIWs are used at much higher temperatures (typically from 600 °C to 1800 °C) than most other glass and rock wools.
