What is Pearl starch?
What is Pearl starch?
Pearl is a dent unmodified starch, ideal for use in paper of all grades. It can be used to improve strength or retention, in addition to improving drainage and surface properties across your paper product portfolio.
How does starch strengthen paper?
Function: Starch contributes to the stiffness and bonding within a sheet of paper. Cationic starch is added to improve internal bond, tensile strength, and as part of certain retention and drainage programs. It also is widely used for the preparation of sizing agents such as alkenylsuccinic anhydride (ASA).
Why is starch used in paper making?
Starch in the Paper Industry Starch is used as a flocculant and retention aid, as a bonding agent, as a surface size, as a binder for coatings, and as an adhesive in corrugated board, laminated grades, and other products. The major starch sources are corn, potato, waxy maize, wheat, and tapioca.

What is cationic starch?
Cationic starches are widely used as wet end additives in paper making. They provide many benefits, classified into 4 categories: improvement of mechanical strength; better retention of fines and fillers; faster drainage; reduction of waste water pollution.
How do you make cationic starch?
Cationic starch is produced by treating a slurry of partially swollen granules of starch with a reactive compound. An example of such a reagant is epoxypropyltrimethylammonium chloride. This reagant contains a quaternary nitrogen, yielding a positive charge that is independent of pH.
