ZircoFlex Foil on Silencer Unit

ZircoFlex® is a revolutionary flexible ceramic heat shield material, offering superb thermal barrier performance at minimal weight and minimal thickness. The material is produced as a thin aluminium or gold backed foil that is:

  • Flexible - ZircoFlex® is easily bent and manipulated to suit different geometries, and can even be folded tightly through 180o without damaging the thermal barrier.
  • Lightweight - ZircoFlex I® weighs only 0.46kg/m2 (0.23kg/m2  for ZircoFlex® Gold).
  • Extremely thin - at 0.25mm overall (for ZircoFlex I®) needing only minimal space for installation.
  • Metal backed, so the material is robust and easy to handle.
  • Easily cut and installed by hand or machine.
  • Easily fixed in place using mechanical fasteners or high temperature adhesives (supplied separately by Zircotec).

ZircoFlex® is available in a number of formats

  • ZircoFlex I® - this is ZircoFlex® in its single thickness format (as outlined above);
  • ZircoFlex II® - an engineered double thickness format offering additional thermal barrier performance and a little more rigidity; still thin (~0.5mm) and lightweight (~1 kg/m2);
  • ZircoFlex III® - an engineered triple thickness format offering yet more thermal performance. This is a relatively rigid material that can be used to construct small self-supporting structures, though it is still easily cut and bent to shape and is still relatively thin (~0.85mm) and lightweight (~1.5 kg/m2). 
  • ZircoFlex® FORM - a high performance yet lightweight structural ceramic heatshield material offering exceptional levels of that can be easily bent and formed to protect against both radiant and conductive heat in a single easy to use product.
