Effective production process for polymer-based particles
The encapsulation of active ingredients is essential for many applications. It prevents incompatibility between different materials or protects an active ingredient by the complete separation from the environment. For example, vitamins have to be protected against oxidative influences. In other examples, encapsulation improves the handling of adhesive materials, preserves reactive agents or permits the selective control of the release of an active ingredient or perfume. In our research efforts, we focus on polymer-based particles and capsules. In the development of new materials with improved properties, polymer particles have proven to be an indispensable key material for many application areas. The micro- (larger than 1 µm) and nanoscale (smaller than 1 µm) polymer particles play a crucial role in the optimization of functions and applications. Depending on the requirements of the application, we can realize homogeneous particles as well as capsules with a "core-shell"- or a "multi-core" morphology.
“We increase the efficiency and availability of your active ingredients“
The material selection based on many years of experience combined with effective production processes is part of the expertise that allows us to develop polymer-based particles or capsules with customized properties. Our strength lies in the adaptation or the realization of continuous processes for the formulation of these polymer-based particles and capsules. We adapt chemical composition, particle size, morphology and surface functionalization according to customer requirements.
