POLYTREND® 7-Series liquid color systems for on-demand coloring of plastics - a full line of environmentally friendly, unique and well-proven liquid colors coupled with our newly developed, highly innovative mixing and dosing equipment -- will raise the standard of coloring plastics to a higher level. These revolutionary developments optimize the coloring process, increase flexibility and reduce working capital. Color wheelBy mixing system colors, we can cover parts of the color wheel (figure right page). Each point in the color wheel represents a color shade. The more system colors you can choose from the more color shades can be made. Evonik offers a basic selection of standardized system colors that offers the ability to cover a significant portion of the color wheel. At the processing site this enables the customer to quickly respond to almost every color demand in the market. Special effect colors like pearl and metallic effect can be added to this basic selection of system colors. Color collectionsWith each system we supply RAL color formulations which have been randomly checked in plastic. Upon request Evonik could also offer other formulations like Pantone, HKS or others. Besides this our color matching laboratories are always available for quick and efficient support in specific color matchings requests. The color formulations we provide are start formulations which might be fine tuned by the end user. Dosing levelsThe blends of liquid system colors are generally dosed in a range varying from 0,02% up to 1,0%, which is an economical advantage compared with dosing of masterbatch (1-3%). Impact on the polymerThe amounts of color added to the polymer, are so low that either no or insignificant changes in polymer properties are apparent. Typical physical propertiesOur solutions are tailor made. We adapt our selection of system colors, keeping your demands in mind. Our system colors are based on pigments and dyestuff and other coloring materials which have excellent properties in the following areas: Light fastness, Weatherability and Heat Stability All colors are based on components which meet the various requirements of the European Union. Most colors are FDA-listed.
CompatibilityAbove color system can be used for coloring the following polymers: PP, LLDPE, LDPE, HDPE, HIPS, GPPS. For alternative polymers additional system colors can be offered. Our carrier system has proven to be compatible with the following polymers: LDPE, HDPE, PP, TR.PP, GPPS, HIPS, ABS, TR.ABS, SAN, ASA, SBS, PMMA, PC, PC/ABS, PA6, PA6.6, PA11, PA12, TR.PA, PBT, PET, POM, CA, CAB/CAP, PVC, UPVC, PUR. Other polymers can be evaluated. |
