6" x 6" x 1/4" THICK
You are buying on One Piece of Kaowool Thermal Insulation Board. It is "M" Grade Board. It measures 6" x 6" x 1/4" thick.
Be sure to view all photos as they are an integral component of the item description.
Kaowool "M" Series Board has a Maximum Temperature Raring of 2300 degrees F
1260 degrees C). It has High tensile strength at 200 - 300 PSI.  High-performance, board, paper and felt products from ThermalCeramics are the preferred choice over traditional fiberglass,textile, or metal products for thermal, acoustical, or filtration management.
Kaowool  "M" Grade Board products are produced from Kaowool high purity fibers and organic binders in a unique paper/felt making process. Each of these paper products are noted for their excellent tensile strengths and outstanding handling characteristics. The "M" Grade Board ismanufactured from cleaned Kaowool high purity ceramicfibers resulting in a premium paper product with low shot (unfiberized material) content. The organic binding starch which hold the board together during the forming process burns out and exhibit the smell of burning paper upon the first firings and turns brown. Do not be alarmed. The binders can be "pre-burned" out at 800 degrees C. To achieve the white color it had when received.
Kaowool  "M" Grade Board is useful for
Low thermal conductivity and heat storage
Thin, flexible high temperature insulation
Easily die-cut to form complex shapes for high temperature gasketing
Excellent backup and expansion joint material
High temperature gaskets and seals
Refractory back-up insulation
Appliance insulation
Separating media for heat treating metals
High temperature filtration
High temperature expansion joint packing
Glassware separating media
Parting agent for brazing operations
Hot face and backup lining for lab furnaces
Aluminum distributor pan lining
Super alloy ingot mold lining and hot tapes.

Chemical Properties
A small amount of organic combustible binder will burn out at approximately 300°F(149°C). Caution should be exercised during the initial heating. Adequate ventilation should be provided to avoid potential flash ignition of the binder out-gassing or avoid air
entry while at elevated temperatures.
