Product Description

Ceramic Fiber Bulk for heat insulation

Ceramic fiber bulk is made of coal gangue by melting at high temperature through 

resistance furnace, before being blown or spun into fiber.

As a neutral and acidic material, except reaction with the strong acid-alkali, ceramic fiber won’t

be eroded by other weak alkali, weak acids, or water, oil, steam, or be infiltrated with lead, 

aluminum or copper, featuring excellent flexibility and elasticity,also lightweight,heat insulation,

low thermal conductivity etc.


Ceramic fiber bulk application 

(1)Raw material for fiber blanket, board products; Raw material for fiber textile products;

(2) Joint sealing and filling insulation for industrial kilns and fuming channel and high temperature pipes

(3) Raw material wet processed products; 

(4) Fiber spraying;

(5) Raw material for coatings and castables; 

(6) Insulation fillings for corner and complex space.
