Product description:
Ceramic fiber paper is produced from refractory fibers plus a small amount of organic binder.
It has excellent thermal insulation properties, can be handled by hand, and is convenient to construct.
Very flexible and resistant to tearing. Particularly suitable for deep processing. Such as: laminated structure, punched, curled or folded.
It is a chemically stable insulating material with a maximum temperature of 1260 ° C.
The organic binder can be completely burned out when heated for the first time, and the loss on ignition temperature is about 300 °C.
