REPI produces liquid colours, formulated ad hoc to ensure maximum compatibility and performance for the specific polymer, be it PET, HDPE, PP, PVC, ABS, PC, PMMA and recycled polymers. The liquid colouring technology ensures excellent dispersion, high concentration and colouring power, precision in dosing as well as efficiency in logistics and storage. There are no limits to the shades that can be formulated, which range from transparent and translucent, to opaque with pearlescent, metallic, matt effects. Depending on the final application, REPI formulates colours that comply with specific regulations in the food and medical sectors. The liquid colouring technology allows to obtain excellent dispersion even at very low dosages. The colorant can be formulated together with specific additives to obtain a complete product that gives desired aesthetics and performance in a single solution. The high colouring power, extremely precise dosage, efficient logistics and storage make REPI technology a highly sustainable solution for the colouring of thermoplastic polymers.
