Abstract
A laser markable Acrylonitrile-Butadiene-Styrene (ABS) terpolymer formulation suitable for a number of applications and in particular, telecommunications terminals and keypads. The ABS terpolymer comprises Acrylonitrile (20-24%), Butadiene (14-17%), Styrene (59-63%), Medium Color Furnace Black (0.008-0.015 PPH), Iron Oxide Red (0.003-0.005 PPH), Titanium Dioxide (0.6-3.50 PPH), Silicon Dioxide (0.07-0.2 PPH), Zinc Carbonate (0.05-0.70 PPH) and Aluminum Hydroxide (0.05-0.25 PPH). The ABS so produced is characterized by desirable performance characteristics, e.g., mechanical strength, impact resistance, gloss, stain resistance, molding processing properties and color, as defined in a 3D color system of the color value (L-star (=67.53)), hue (a-star (=1.15)), chroma (b-star (=3.46)).
