Silica Fiber Needle Mat

  • Working temperature 1000℃
  • Melt temperature 1600℃
  • Application Thermal insulation barrier, pad, mattress; Automotive, motor exhaust
  • Fiber diameter 6-9um

Silica fiber needle mat/felt is made by 100% amorphous silica fiber SiO2≥94%. The fiber imparts silica felt excellent extremely high temperature resistance. It is ideal material used for 1000℃ heat insulation. Pre-shrunk silica needle felt can be optional. 

Features
Extremely high temperature resistance rating to 1000℃ and low thermal conductivity.
Non-combustible and wow heat shrinkage and LOI
Good sound absorption
Abestos free and heathy
