parameter. Durability of these grades can be described as medium. Plastic Type 3 includes grades characterised by special surface treatment with aluminium and silicon (or sometimes zirconium instead or in combination with silicon) compounds and special organic additives usually imparting hydrophobicity to the surface of pigment particles. These grades have been designed for maximum pigment processability in the production of various types of plastic for which durability is a critical parameter (for example, the production of PVC window profiles). Durability of these grades can be described as superior. Some manufacturers also use rutile crystal lattice doping technology to reduce its photochemical activity and improve durability. “The top five global TiO2


manufacturers all have at


least one, but usually several, grades of each of these types in their product lines, covering all the main plastic application areas,” says Gonchar. “Of the five main Eastern European producers, only Police, Precheza and Cinkarna have special plastic grades in their product lines. Police has only Type 1, while Precheza has Types 1 and 2 and Cinkarna has only Type 2. Ukrainian manufacturers Sumyhimprom and Crimea Titan currently have no special plastic grades in their product

Grade development Gonchar highlights a number of technical trends over the past 10-15 years for TiO2


in plastics. “There has


been a move away from grades with a hydrophilic surface to hydrophobic grades. There has also been a move towards the production of grades that have water-repellent additives, chemically bonded to the surface of TiO2


. The market is rejecting grades containing water repellents, which are only physically www.compoundingworld.com


lines and usually offer their universal paint grades to manufacturers of plastics. “Plastics grades are manufactured by only two of the manufacturers. Ishihara has several


five Japanese TiO2


grades of Types 1 and 2, although we have no informa- tion about the production of Type 3 grades. However, the company apparently offers paint grades with high durability for this market segment. Sakai produces all three plastic type grades. Of the four Indian manufacturers, only KMML has one Type 2 grade in its product range. South Korean manufacturer Cosmo does not have any plastic grades in its product range. There are several dozen Chinese TiO2


manufacturers. We


estimate that 12.5% produce Type 1, 17.5% produce Type 2 and 15.7% produce Type 3.”
