GPC Offers Choices in Liquefied Cationic Starches to Meet the Demands of Your Application

When it comes to liquefied cationic starches, Grain Processing Corporation offers choices to fit and meet your needs. Whether you need a ready to use liquid cationic starch for papermaking to enhance strength, retention and emulsification or have a need in water treatment systems for coagulation and flocculation, we can deliver. All of these liquefied starches provide cationic levels ranging from high to very high. They all employ a quaternary amine technology that remains functional in a wide range of pH, acidic to alkaline.

The liquefied CHARGEMASTER® cationic starch technology provides elevated cationic substitution levels to provide advantages for papermakers. Liquefied CHARGEMASTER® cationic starches also provide a performance bio-based renewable resource alternative for water treatment facilities.

CHARGEMASTER® L435 is a high degree of substitution (cationic charge) liquid starch for papermaking and is FDA approved for food contact papers. L435 delivers performance in wet-end retention, internal strength, broke coagulant for scavenging anionic interfering elements and ASA emulsification.

CHARGEMASTER® L340 is a much higher level cationic charged liquefied starch for papermaking and is also FDA approved for food contact papers. L340 delivers performance in wet-end retention, internal strength, broke coagulant for scavenging anionic interfering elements and optical brightener retention.

CHARGEMASTER® L360 is GPC’s highest cationic level liquefied starch and is used for water treatment. L360 gives water treatment operators a bio-based renewable resource choice for their coagulant and flocculant performance needs. L360 is not FDA approved for food contact papers.

Liquefied CHARGEMASTER® cationic starch elevated substitution levels provide:

  • Increased retention of fines and sizing chemicals in demanding systems
  • Increased sheet strength properties
  • Reduced dusting and linting
  • Increased sizing and reduced size addition
  • Improved machine performance with reduced tray water consistency
  • A bio-based renewable resource of water treatment system coagulants and flocculants

GPC’s liquefied cationic starches provide high level of charge (degree of substitution) that delivers performance benefits. These pre-dispersed liquid starches eliminate many of the costs of cooking (i.e. labor, steam and footprint). They are also easy to use because of their low viscosity; just dilute and go. GPC’s Technical Service group is available to help with your specialized application needs. For more information, please contact us here or at 563-264-4265.
