flexshield
A flexible radiant heat shield produced by bonding graphite foil to a single woven layer of carbon fibre carbon composite. It provides a protective barrier between graphite insulation materials and the furnace hot zone. Flexshield is recommended as a protective heat shield on the hot-face of high temperature insulation packages. It can be installed directly over carbon/graphite felt or conventional rigid board insulation. Flexshield is optimized to be extremely durable and yet pliable enough for bending.

Flexshield prevents heat pack erosion from high velocity gas flows and protects the insulation from damage due to dropped parts.
The use of Flexshield cost effectively extends the lifetime of conventional insulation heat packs, which are susceptible to erosion.
Flexshield covers the face of the insulation package by conforming to the walls of both round and square hot zones. It can be attached directly to rigid board insulation with drywall-type graphite screws or held in place in the conventional manner with threaded studs attached to the hot zone cage.
