ANGEL-CATIONIC STARCH(Maize based)
Cationic Starch(Maize based) is used in the paper making industry to improve the dry strength of the finished sheet. It has been developed to provide the paper industries with consistent, cost effective quality product with a unique features .
Cationic starch(Maize based) has effect on
Improving durability properties
filler retention.
HOW CATIONIC STARCH WORKS IN PAPERMAKING:
Cationic Starch(Maize based) contains quaternary amino groups that act as cationic charge carrier. It will adsorb to cellulose and pigments, induce patch-type and bridging flocculation and strengthen the bonding between furnish components.
The strengthening effect of Cationic starch(Maize based) is much greater in a filled sheet with high filler level. This is because of the effect of the starch as a mucilage or lubricant. When the filler particle is surrounded by cationic starch, the local friction between the filler particle and fibre is reduced and slipping occurs. Thus local stress concentrations are decreased and breaking of water meniscus does not occur. This
results in better sheet consolidation and bonding, as shown in sketch:

SPECIAL FEATURES
Improved retention of fines and fillers
Strength improvement due to additional fiber to fiber bond
Better sheet formation coupled with better drainage
It enhances paper strength, water drainage, retention, improve paper quality; reduced dusting, linting and size addition;
It has a greater control of paper making process hence less paper web breaks and improve paper machine runnability as well as productivity.
Act as a surface size agent, it also improves stiffness, opacity, printing quality and brightness
