1260 Cerablanket

1.Excellent insulating performance.
2.Unaffected by most chemicals except hydrofluoric and phosphoric acids and strong alkali
Features
Low heat strong capacity, Low thermal conductivity
Excellent thermal stability and shock resistance, resist devitrification at high temperature
Excellent tearing resistant
Excellent insulating performance,fire prevention and sound absorption
Double—side needling operation produces tough, resilient and strong blankets, which resist tearing both before and after heating.
Easy cutting and installation
Typical Application
All kinds of industrial kiln linings(hot surface and back lining)
Furnace body expansion joint, furnace door,top cap seals
High building fire proof and heat insulation
Thermal resistance component of auto industry with
High temperature filter media
Insulation for field stress relieving of welds
