agrimer™ pvp polymers
chemistry: PVP Polymers
Agrimer™ pvp products are linear, non-ionic polymers that are soluble in water and many organic solvents. They are pH stable, and have adhesive, cohesive and binding properties. The unique ability to adsorb on a host of active ingredients makes agrimer™ pvp homopolymers preferred co-dispersants in many formulations. Agrimer™ homopolymers have a high glass transition temperature.
Lower molecular weight (Mw) agrimer™ polymers (agrimer™ 15 and agrimer™ 30 polymers) are suitable for applications where dusting is a concern, such as seed coatings and agglomeration. Higher Mw agrimer™ polymers (agrimer™ 90 and agrimer™ 120 polymers) can build formulation viscosity faster and provide excellent binding and film forming properties. Higher Mw agrimer™ polymers are also excellent carriers for pheromones and other attractants.
