White pigments – rutiles for indoor applicationsinorganically untreatedRutile titanium dioxide pigments are commonly inorganicallycoated, mostly with oxi-hydrates of aluminum, silica or zirconium.In spread applications these components may not be compatible tothe polymer system. As SACHTLEBEN RU 5 and SACHTLEBEN R 320are not inorganically coated, adversely effects are reduced oravoided.SACHTLEBEN R 320SACHTLEBEN R 320 is an inorganically untreated but polyolcoated rutile titanium dioxide pigment. Its crystal and particlesizes position SACHTLEBEN R 320 in the group of warm undertoneplastics grades.SACHTLEBEN RU 5SACHTLEBEN RU 5 is an untreated micronized titanium dioxidepigment of rutile crystal structure possessing extremely goodoptical properties - high lightness and blue undertone - combinedwith very good dispersibility.sachtleben RU 5 SACHTLEBEN R 320Titanium dioxide classification R1 R1Inorganic treatment(compounds based on:) - -Organic treatment Polyol PolyolTiO 2content [%] approx. 98 approx. 98Undertone bluish warm8
white pigments – AnATASE TITANIUM DIOXIDEAnatase - a specialtyin its own rightTitanium dioxide crystallizes in three modifications, known asrutile, anatase and brookite; only rutile and anatase are of commercialsignificance. Anatase, with its slightly lower scatteringpower, is not a true competitor for rutile in standard whitepigment applications, and the selection of anatase as a whitepigment should be based on other specific properties which onlyit possesses; the difference between the crystal hardnesses ofrutile and anatase is of particular importance in this context.Anatase, at 5.8 on the Mohs hardness scale, has a lower physicalhardness than rutile, at 6.5; this is the reason for the use ofanatase pigments in a wide range of plastics applications, sincethis product‘s lower abrasiveness reduces wear on processingequipment. Anatase‘s blue-shifted absorption edge gives it amore bluish tint than rutile, and therefore makes it suitablefor use in unique, slightly blue-tinted white plastic products.In combination with optical brighteners, this same shift in thepigment‘s absorption edge produces bright and glossy solutions.Diffuse reflectancebehaviour of RUTILEand anataseDIFFUSE REFLECTANCE [%]1009080706050403020TiO102RutileTiO 2Anatase0300 350 400 450 500 550WAVELENGTH [nm]HOMBITAN LOCRK HoMBITAN MCT 300 HOMBITAN LO-CR-SM HOMBITAN LC-STitanium dioxide classification A1 A1 A2 A2TiO 2content [%] > 98 > 98 95 97Inorganic treatment(compounds based on:) AI AI AI, Mn AIOrganic treatment Polysiloxane Polysiloxane Polyol PolyolUndertone bluish bluish bluish bluishHardness (Mohs) 5.8 5.8 5.8 5.8Filter pressure test very good excellent very good very gooduniVERSAL Polyolefine Films / Fibers PA Fiber PET PBT Fiber9
