Ceramic fiber board

Ceramic fiber board is made of aluminum silicate refractory fiber(ceramic fiber bulk) which is processed into board by mixing, vacuum formed and heat treatment, with good mechanical strength and high temperature resistance. It has organic or inorganic type. It can be used as thermal lining and back lining insulation material for all kinds of kilns and furnace. It has excellent performance in high temperature applications.

Available type as following: 

R -Regular Type ( dry / organic) 

SH -Surface harden Type (dry/add surface strength/organic) 

EH Entirety harden Type (dry/add entirety strength / organic) 

PF -Pre-fire Type( without smoke / low shrinkage/ inorganic) 

PFSH -Pre-fire Type and surface harden (without smoke / add surface strength / low shrinkage/inorganic) 

PFEH -Pre-fire Type and entirety harden( without smoke / add entirety strength/ low shrinkage/inorganic) 

WR -Water repellent ( dry / hydrophobic )
