Various ceramic fiber blankets:
The blankets are made from ceramic fiber cotton which can be usually divided into four types via spinning and forming process: ordinary, standard, high pure and zirconium containing. The manufacturing process of blankets involves needling, thermoforming, vertical and horizontal cutting, winding and other working procedures.

Ceramic fiber blanket has uniform diameter, long fiber and low content of slag balls, which improves fiber interweaving degree, lamination resistance, wind erosion resistance, flexibility, tensile strength and other performance so as to enhance the application performance of acupuncture blanket and reduce material loss.

Ceramic fiber blankets will not be used together with any binder to guarantee that the product has good feasibility and stability in different kinds of environment.

Classification temperature:
Ordinary ceramic fiber blanket 1100ºC
Standard ceramic fiber blanket 1260ºC
High pure ceramic fiber blanket 1260ºC
High alumina ceramic fiber blanket 1360ºC
Zirconium contained ceramic fiber blanket 1430ºC

Working temperature:
It depends on material using conditions, kinds of heat source, environmental atmosphere and other conditions.  


Application
