About ROWASOL
Since 2004, ROWASOL GmbH has been a specialist within the ROWA GROUP corporate group from Pinneberg for high-quality liquid colors (color pastes) and additive concentrates for the efficient processing of plastics. The dispersions consist of a non-volatile carrier system with pigments or dyes dispersed in it and are mixed homogeneously with the plastic directly on the processing machine by full coloring. The core competence lies in the coloring of thermoplastics processed by injection molding or extrusion, including biopolymers and recyclates. Customer-specific solutions are developed and produced at the Karstädt site in Brandenburg; implementation at the customer is accompanied by technical customer service. The portfolio is complemented by ROWAMETRIC dosing systems for fast, clean color changes, the reusable container ROWASOL COLOR CUBE, contract manufacturing as well as coloristics and self-coloring with monopigment concentrates.

Products and Processes
Liquid colors / color pastes
Dispersions of pigments or dyes in a non-volatile carrier system for full coloring of thermoplastics in injection molding and extrusion.
Additive concentrates / additive dispersions
Concentrates for the functional enhancement of plastics directly in the processing machine.
Monopigment concentrates
Basis for self-coloring; formulation with 10 to 12 monos covers a broad color spectrum reproducibly.
GreenLine bio-based colorants
Portfolio of around 20 bio-based colorants, e.g. from turmeric, algae, tomatoes and lignin, tested inter alia on the biopolymer Bio-Flex S 7514.
