FREEFLOW®

PROPERTIES & ADVANTAGES

  • Low thermal conductivity
  • Non combustible
  • Easy to install
  • Suitable for automated feeding of complex shapes
  • Environmentally friendly, free of organic binders
  • Resistant to most chemicals


Pourable products

FREEFLOW® is a pourable microporous powder with very good thermal properties. The formulation is an opacified blend of pyrogenic silica. FREEFLOW® is suitable for filling complex shapes & cavities with demanding thermal specifications. It offers insulation solutions for applications where no other conventional insulation can be used.

FREEFLOW® has been recently improved by upgrading its formula. It now offers the same thermal performance at a reduced density, resulting in a lower installed cost.

Typical applications
< #Back#
Microporous insulation offers an extremely low thermal conductivity, close to the lowest theoretically possible at high temperatures. Microporous materials are the preferred choice when a large temperature reduction is required within a limited space, or when strict heat loss or surface temperature requirements are specified.

  • Fuel cells (SOFC) & reformers
  • Exhaust systems
  • Filling of complex cavities
