Introduction to HTIW Products

Low Biopersistent Wool (LBP)

Refractory Ceramic Fiber (RCF)

Polycrystalline Wool (PCW)

  • Made of synthetic vitreous and polycrystalline mineral wools
  • Defined by a classification temperature above 1832°F (1000°C)
  • Typically used at temperatures above 1100°F (600°C)
  • Necessary for many high-tech products due to their versatile characteristics
  • Essential for minimizing energy consumption and greenhouse gas emissions
  • Used at much higher temperatures than most other glass and rock wools

Some Common Characteristics of HTIW:

  • High temperature resistance
  • Low thermal conductivity
  • Excellent thermal shock resistance
  • Chemically neutral
  • Great flexibility
  • Low thermal mass
  • Light weight

High Temperature Insulation Wools are part of a larger group of Synthetic Vitreous Fibers (SVF), which also includes fiberglass and mineral wool.
