Ceramic Fiber Paper

Thin, flexible high-purity alumina-silicate fiber sheets for precision thermal insulation

Ceramic Fiber Paper - Flexible Thermal Insulation Sheets

Product Overview

ZOUYU ceramic fiber paper is manufactured from high-purity alumina-silicate fiber, processed into thin, flexible sheets with uniform thickness. The paper-making process produces a product with excellent surface finish, consistent density, and superior handling characteristics, making it ideal for precision applications where thin-profile insulation is required.

Key Features

  • Uniform thickness and smooth surface finish
  • Excellent flexibility - can be cut, folded, and wrapped easily
  • Low thermal conductivity for effective heat insulation
  • High dielectric strength for electrical insulation applications
  • Good resistance to chemical attack and molten metal splash
  • Low heat capacity for fast thermal cycling
  • Easy to stamp, die-cut, and laminate

Applications

Gasketing & Seals Expansion Joints Pipe Wrapping Furnace Door Seals Electrical Insulation Automotive Heat Shields Investment Casting Glass Industry
