A fete of pigments for various applications at the K

  • Swiss firm Clariant’s new PV Fast Yellow H4G is to replace lead chromates in PVC and polyolefins. This FDA-compliant organic benzimidazolone is said to have three times the colour strength of lead-based pigments, so lower levels are needed, as well as opacity and weather fastness. Also new is quinacridone PV Fast Pink E/EO1, made with bio-succinic acid, for colouring toys and food packaging. Its recently launched Polysynthren Black H is an IR-transparent dye that enables easy sorting of black articles made from nylons, ABS, and PC during recycling.

  • Huntsman will feature pigments for applications ranging from packaging and construction profiles to automotive and electronic components. It will also feature its new Tioxide TR48 TiO2, said to process well, even at high temperatures. Designed for use in polyolefin masterbatches, BOPP films, and engineering compounds, TR48 boasts easy dispersion and tint-reduction capabilities for low-VOC formulations. It is geared to premium and general packaging, consumer electronics, and automotive components.

  • Lanxess’s subsidiary Rhein Chemie Additives will feature the latest in its line of organic Macrolex Gran colourants, said to provide brilliant colouring of plastics such as PS, ABS, PET, and PMMA. Consisting of hollow spheres, the high-purity Macrolex microgranules can be easily crushed, allowing for quick and even dispersion. The free-flowing properties of the 0.3-mm spheres make precise metering easier and prevent clumping during mixing.
