CeraTex® 3170G

CeraTex® Ceramic Fiber Paper with Graphite Surface is an alumino-silicate ceramic fiber-based non-woven fabric with a single-sided graphite surface.  CeraTex® is manufactured through a special paper-making process with high purity washed fibers, suitable for high temperature insulation up to 2300°F.

Main Characteristics and Properties
  • White color, lightweight, flexible, good handling strength and good uniformity
  • Resists temperature as high as 2300º F, ceramic fiber paper component of this product is fire resistant**
  • Low thermal conductivity, low heat storage, thermal shock resistant
  • Good dielectric strength
  • Excellent corrosion resistance (Resistant to most chemicals except hydrofluoric, phosphoric acids and concentrated alkalis)
  • Graphite surface (single side) provides superior heat resistance and non-stick properties, especially useful in applications which require an industrial-level trivet

** This product contains an organic binder which burns out at high temperatures.  Smoking/outgassing may occur during this burnout, but the product’s physical properties are maintained.
