Testing methods
  • Specific weight - Was determined by automatic gas pycnometer in g/cm3
  • Bulking volume - Denotes the volume of 1 kg loosely poured dye, expressed in litres
  • Melting point [°C] - Was determined by DSC method (Differencial Scanning Calorimeter)
  • Concentration for 1/3 of standard    depth - Concentration of the dye in % for coloring of polystyrene containing      1% TiO2 to get 1/3 of standard depth
  • Transmission curve - Graphic image of dependence of transmission on wave length measured    on chips made of polystyrene Krasten 127 with the thickness of 2 mm and    content of dyestuff of 0,01 %
  • Reflection curve - Graphic image of dependence of reflection on wave length measured on    chips made of polystyrene Krasten 127 with the content of dyestuff of 0,01 %    and 1 % TiO2.
  • Fastness to bleeding - Testing was done according to Resolution AP(89) 1 (Council of Europe    Commitee of Ministers) for using of colourants in plastic materials comming    into contact with food. Chips made of polystyrene Krasten 127 with content of    0,1 % of dyestuffs was in contact with food-simulating liquids for 5 hours at    50 °C. Bleeding (staining of liquids) was assessed using 5 degree Intemational    Grey Scale ISO 105 A2 where 5 indicates no bleeding
  • Resistance to radical-forming agents - Polyester resin Aropol FS-9945 with content of 0,05 % dyestuff was    cured 30 minutes at 80 °C using addition of 2 % hardening agent. The change of    color shade after curing was asessed in comparisson with the colour of the    solution of dyestuffs in the resin before curing.
    + the dye is suitable (without colour change)
    - the dye is not suitable (heavy colour change)
  • Light fastness - Xenotest - ČSN EN ISO 105 B02:2000. Determined according to blue    scale, by it degree 1 denotes the lowest fastness, degree 8 the highest one
    A - Full Shade 0,05 % in PS
    B - 0,05 % + 1 % Ti02 in PS
  • Heat Resistance - Was determined by injection moulding machine over the    temperature range 200 - 300°C Moldings were prepared after 5 minutes dwell    time at each test temperature and were compared against control moulding    prepared at the lowest test temperature - 180 °C (dyeing 0,1 % + 1 % TiO2 in PS Krasten 127)
  • Migration - Tested by placing a chips of coloured    PS in contact with a sample of PS containing only 1 % TiO2 for 1    day at 70°C. Any stain was assested using ISO Grey Scale, where 5 indicates no    stain.
