LUDOX® Colloidal Silica
for Paper Retention and Drainage
LUDOX® colloidal silica can be used as one component of microparticle retention systems in the “wet end” of paper manufacturing.
Typically, a high surface area colloidal silica is used with a cationic starch, poly-acrylamide, or other cationic polymer to flocculate cellulosic fibers for use in the papermaking process.
An optimized process will result in
-
Higher retention of fiber, and
- Improved water drainage on the web
