Paper & Board

National offers an extensive series of specialty starch product lines to meet a wide variety of wet-end and specialty surface papermaking needs.  We revolutionized paper machine wet-ends 50 years ago with the introduction of our CATO^® cationic starches.  Today, our family of products includes an extensive range of starch bases; innovative cationic, amphoteric, hydrophobic, viscosity modified and multi-component specialty starch formulations; and a wide range of specialty synthetic and biopolymers used as rheology modifiers, retention aids and other functional purposes.  With more than 50 years of practical papermaking know-how, National’s experienced technical service teams know how to find production efficiencies and reduce your manufacturing costs per ton of paper produced through increased machine speed, reduced starch or additive usage, better runnability properties and product cleanliness.

Specialty starches
Specialty starch products offer papermakers the benefits of improved runnability, reduced basis weight, increased production and differentiable surface property performance.  Wet-end specialty starches offer increased strength, development, drainage and retention options in acid, neutral or alkaline papermaking.  Specialty starch surface applications improve finished paper/board printability, surface strength and oil and grease resistance applications.  Papermaking.

Specialty synthetic polymers
Specialty synthetic polymers and biopolymers that act as rheology modifiers, retention aids, FDA additives, dispersants, anti-static agents and thickeners in paper and board applications. www.alcochemical.com
