Effect Pigments are widely used in plastic materials to achieve gold, silver or pearlescent colours. The main aspect is to achieve a differentiation and to upgrade the value of the end user product. The first part of the presentation describes the production, processing, optical aspects and the special features of aluminium-, gold bronze-, and pearlescent-pigments. This will be followed by the introduction of new effect pigments such as the platinum dollar aluminium pigments which enable "spray coated like" silver effects in mass coloured plastics. In addition a new generation of pearl pigment on the basis of artificial glass substrates will be highlighted. Today's key success factor for pigment manufacturers is the ability to provide easy to use product forms with high and consistent qualities such as Eckart's Micropellets. These products enable significant cost reductions compared to regular pigment powders or pastes in masterbatch production as they enable higher production speeds and easy dispersion. They also significantly reduce cleaning times in production. Finally a short outline on use of aluminium pigments to improve insulation properties of plastics will be given. Energy saving is Megatrend especially at today's crude oil prices. Aluminium pigments reflect IR light and therefore can be used to improve the insulation and help to keep the heat inside (winter) or outside (summer).
