Better High Temperature Properties
Ammonia stabilized
particles give stable bonds at high temperatures producing less shrinkage
and less cristobalite at temperatures up to 2300oF.
Best Product for Rigidizing
Larger particles
soak in further and giver stronger, harder rigidized products; significantly
reduced sodium results in less shrinkage at end-use temperatures.
Stronger Bonding and Hardness
Larger particle size yields higher green strengths (i.e., modulus of rupture) and harder
refractory fiber shapes.
Saves Money
Balanced silica to starch floccing ratio is more economical giving high strength with less
colloidal silica in formulation.
Flocs with Cationic Starch
Negative surface charge flocs cationic starch refractory fibers together to form a three
dimensional floc for good product strength.
