PREGEL/PRECOOKED CATIONIC STARCH is developed specifically as a replacement for cationic potato starches with the added benefit of greater strength and hardness. This has a high nitrogen content (0.3% minimum ), This starch will floc 25 - 30% more colloidal silica than other regular Cationic Flake (0.2% N2) giving it an advantage in high silica formulations (8% by weight of fibers).
Typical Properties
1) Appearance : Off WHITE powder
2) Bulk density ,pcf : 18-24
3) Moisture: 7-8%
4) Ph: 6-8
5) Ionic Character: Cationic
6) Nitrogen Content : 0.3%Minimum
Application : This PRECCOKED CATIONIC starch is used in making CERAMIC FIBERS .These CERAMIC FIBERS are used as INSULATION BLANKET in various industries like REFRACTORIES etc.
Note proper use: For best results, always add starch to slurry before the colloidal silica; the cationic starch serves to give a cationic charge to the fibers for efficient exhaustion of the negatively charged silica particles on fibers.
