WESPOLY™
Engineered wet-end cationic starches.
The Wespoly™ product line is a series of high quality, quaternary cationic starches engineered to improve retention and drainage while maintaining strength in paper and paperboard production. Wespoly™ starches are specifically designed for retention of ash and fillers.
Benefits of Wespoly™ line of starches:
| Fine Paper: |
Improved retention of ash/filler and fines, increased dry strength properties.
|
| Kraft Paper (bags): |
Increased dry strength properties, porosity, drainage and retention.
|
| Kraft liner: |
Increased dry strength properties, drainage and retention.
|
| Board: |
Increased ply bond, drainage and retention.
|
| Newsprint: |
Improved mechanical dry strength properties (linting), drainage and retention.
|
Successful applications of Wespoly™ (Case histories):
Large West Coast linerboard mill changed to our engineered Wespoly™ product line, which increased retentions while decreasing starch consumption by 20%.
Second West Coast linerboard mill changed to our engineered product line resulting in increased productivity with lower starch consumption.
Small West Coast fine paper mill also changed to Wespoly™ engineered product, eliminated a retention aid, and improved paper quality while reducing starch consumption. |

Potato starch has a greater bond-forming ability and higher amylose molecular weight.
It also has lower lipid and protein levels which make it more efficient than corn.
Lower lipid levels allow either increases in internal bond strength, decreased use of starch or both.
In many applications, potato starch is the better choice!
