Ceramic Fiber Paper for Thermal Insulation

Ceramic fiber paper from YufengRecconsists primarily of high purity alumina-silicate fiber and is made through a fiber washing process. This process controls the content of unfiberized shots to a very minimal level within the paper.Our ceramic fiber paper features light weight, structure uniformity and low thermal conductivity, which serve as a perfect solution for high temperature insulation, chemical corrosion resistance, and thermal shock resistance.
This ceramic fiber paper can be used in various types of refractory and sealing applications and is available in 3 grades with a variety of thicknesses, widths, and temperature ratings.Standard grade: Maximum service temperature of 1260ºC (2300 ° F)
High- Alumina grade: Maximum service temperature of 1360ºC (2300° F )
Zirconia grade: Maximum service temperature of 1430ºC (2600° F )Standard Thicknesses: 1/32", 1/16", 1/8", 1/4"
Standard Widths: 24" and 48"Standard Packaging: Carton BoxesKey Features
