Product Description

Intro:
Ceramic fiber is made of high quality coke gems, calcined coal gangganges, fly ash and other raw materials, which are melted at high temperature in the electric furnace and spun into ceramic fibers by ultra-high speed centrifugal wire.  It serves as the foundation for fiber products such as blanket, board, pipe and etc. Ceramic fibers are available in a variety of chemistries and diameters which can offer a wide variety of applications.
