White pigments – Rutiles for indoor applicationsSACHTLEBEN RFK 2 and R 405 "UNIVERSAL APPLICATIONS”SACHTLEBEN RFK 2 is an alumina surface-treated hydrophobictitanium dioxide pigment offering rapid dispersibility in a largerange of polymers in dry processing as well as in liquid plasticizers.SACHTLEBEN RFK 2‘s fine crystal and particle sizes positionthe product in the group of blue undertone plastics grades. Thisproduct is recommended for highly filled masterbatches basedon polyolefins and other thermoplastic polymers.SACHTLEBEN R 405 is an alumina surface-treated hydrophobictitanium dioxide pigment offering excellent dispersibility in alarge range of polymers. SACHTLEBEN 405‘s fine crystal andparticle sizes position it in the group of blue undertone plasticsgrades. SACHTLEBEN R 405 is particularly recommended for usein systems in which fineness of pigment dispersion in the polymeris the top priority: polyolefins, styrenics, engineering polymers,etc.. SACHTLEBEN R 405 permits production of highly pigmentedconcentrates, such as polyolefin masterbatches, for instance.SACHTLEBEN R 630 “LOW LACING”SACHTLEBEN R 630 is an alumina surface treated hydrophobictitanium dioxide pigment. It provides fast and excellent dispersibilityin various plastics. As a result of its fine crystal and particlesizes SACHTLEBEN R 630 belongs to the family of blue undertoneplastics grades. It combines excellent optical propertieswith wide resistance to lacing.Allround top performanceCutting-edge products such as SACHTLEBEN R 630 must, of course,are superior to standard pigment products. SACHTLEBEN R 630provides the following benefits throughout the productionprocess:• Effectively no lacing, even at high pigment loadingsand processing temperatures• High bluish white tinting• Good powder properties reducing flow problems anddust production in feed systems• Readily wettable in a large range of polymer systems,assuring high throughput rates• Excellent dispersibility, permitting productionof extremely thin filmsApplicationsSACHTLEBEN R 630 is extremely well suited for all applicationfields which are subject to lacing:• Thin films• Co-extruded multi-layer films• Single and multi-layer bottles• Masterbatches• Credit and check cards• Blister packaging• Food packaging6
