All organic pigment shades shown here are based on a full shade concentration of 0.2% pigment. In the white reductions, the illustrations are based on the respective pigment concentration to achieve 1/3 ISD based on 5% TiO2.

Heat resistance (HDPE)

Resistance to heat was tested according to DIN EN 12877 at SD Vs with 1 % titanium dioxide in the injection molding process. The values quoted are the temperature in °C at which, after a dwell time of 5 min, a color change equivalent to an AE*ab = 3 (DIN 6174) is obtained.

Light Fastness (HDPE和PVC-p)

Light fastness was determined using Xenon lamp exposure tests in accordance with the equivalent test methods ISO 4892-2 or ISO 105-B02. The samples were assessed against the 1–8 Blue Wool Scale as described in ISO 105-B02, Blue Wool 8 denoting the highest light fastness.

Migration

Migration resistance was determined in accordance with DIN 53775 by direct contact between the colored test sheet and a white, flexible PVC contact sheet. The staining of the contact sheet was assessed using the ISO 105-A03 grayscale (GS) for assessing staining, with GS 5 denoting no migration.

Warpage(HDPE）

The influence on the warping tendency of injection-molded HDPE articles was determined in accordance with ISO 294-4/ASTM D955. Warping tendency was assessed by Low, High and not tested.
