ceramic fiber
Refractory (ceramic) fiber cotton
Product variety:
Ordinary (ceramic) fiber cotton
High purity (ceramic) fiber cotton
High alumina (ceramic) fiber cotton
Fiber cotton containing zirconium (ceramic)
The above-mentioned refractory (ceramic) fiber cotton is both lubricant containing and lubricant free
Application scope:
Raw materials for fiber deep processing products (excluding lubricants);
High temperature insulation filling and sealing material (with or without lubricant);
Raw materials for fiber composite products (mixed products).
Product features:
Good thermal and chemical stability (excluding phosphoric acid, hydrogen acid, and strong bases);
Fiber cotton is loose, soft, and elastic within the temperature range of long-term use;
Low thermal conductivity and low heat capacity;
Good resistance to sudden cold and heat;
Fiber cotton containing lubricant has a lower slag ball content and better elasticity than fiber cotton without lubricant.
