Color Service GmbH & Co. KG
About us
Pioneer and innovator.
At Color Service, we have been offering innovative products and services in the field of colouring of plastics since 1970 and thus are among the pioneers in the field of masterbatches.
As part of the TOSAF family, we also offer worldwide service right on your doorstep. Regardless of whether you want to adapt an existing colour or develop a new colour, our experts offer you personalised advice and support. In addition to developing colour masterbatches, we also set up functional masterbatches for our customers. They include UV stabilisers, antistatic agents, flame retardants, laser marking additives and many more. Combination batches made of colour masterbatches and additives are certainly possible as well.
We look forward to hearing from you.

New Masterbatch Carrier System for High-performance Polymer PPA
PPAX is a new color masterbatch carrier system from Tosaf Color Service which is based on the high-performance polymer PPA (polyphthalamide) and whose specially selected pigments allow high processing temperatures. This makes it possible to color products made from it in many different bright colors without affecting this material’s special properties. Unlike PA66-based masterbatches, which are often used as an alternative for cost reasons, the high thermal stability, very good strength, stiffness and toughness values, low moisture absorption and high chemical resistance are also retained in colored injection moldings. All 28 standard stock RAL colors in the PPAX product range can be laser marked and provide a high-contrast color change. Processors using PPAX can take advantage of the high melt temperatures possible with PPA, for example to shorten cycle times, without being limited by the color masterbatch. Testing carried out by Tosaf Color Service at processing temperatures of up to 340°C yielded outstanding results. Even higher temperatures are possible, but must first be confirmed by the processor’s own testing. PPAX-colored samples have demonstrated their high lightfastness and weather resistance. All the colors combine elevated long-term thermal stability with an ability to withstand transient exposure to very high temperatures, for example during soldering.
New metal effect masterbatches for perfect finishes
The new metallic color masterbatches from Tosaf Color Service put an end to the previously typical and undesirable streaks and similar surface defects on plastic parts. The key to this lies in the manufacturer's compounding know-how acquired over the last few decades in combination with the special effect pigments with a rheologically optimized geometry that have only recently become available. As a result, these masterbatches meet the requirements for the cost-cutting, environmentally friendly use of components with brilliant metallic finishes in visible areas. The new masterbatches are available on different carrier systems and, at short notice, in customized shades. They are suitable for all transparent thermoplastics, whereby the brilliance increases with the degree of transparency. They can, however, also be used in opaque plastics such as PC/ABS or PA/ABS blends. The further developed pigment technology makes a major contribution to the considerable reduction in the separation effects that are responsible for streak formation or color deviations, especially in critical areas such as weld lines, cross-sectional transitions or with distinctly three-dimensional, concave or convex contours. The main beneficiaries of this are suppliers to the automotive industry and other segments with extremely high quality demands and with rapidly changing designs that are geared to individuality. Depending on the demands, moldings produced with this masterbatch stand out through their color depth and outstanding surface gloss and also through a delicate structure when eroded molds are used. In many applications, they can replace coated or electroplated parts, which not only saves costs through the elimination of additional work steps, but also makes a considerable contribution to the preservation of the environment. Added to this is the good suitability of the single-sort parts for recycling
