A white paper developed by Hong Kong-based Trinseo technical specialists is providing practical data and research information on selecting the optimum ABS materials for effective coloring.
Historically, manufacturers and fabricators using Acrylonitrile-butadiene-styrene (ABS) resins experience coloring issues with typical ABS resins produced by batch emulsion process. Coloring of ABS resins can typically be achieved by color compounding at a coloring house, or through mixing natural color resins with color masterbatches. The issues include: base color of the natural resins is inconsistent, with potentially significant lot-to-lot variation in the base color of the same natural resin grade, and different natural ABS resins exhibit varying shades of yellow.
When manufacturers of end products receive different lots of ABS resins from the same producer, or different ABS resins from different producers, extra operations are required for color matching, resulting in additional resources and cost. For end product manufacturers using natural color ABS resins with color masterbatches, a higher pigment loading is frequently needed to mask variations in yellow base color from different lots or different grades of ABS resins. Additionally, the thermal stability and light stability of ABS molded parts are primary concerns of end product manufacturers.
