additives – Synthetic barium sulfateANTI-BLOCKING ADDITIVESAnti-blocking additives are used in order to control the adhesionbetween film layers or films and other material in contact withfilms, for example rolls or bars. They should not impact anykind of optical effects to the film, for example specks, color,reduced gloss or angle dependent properties. Anti-blockingadditives based on natural minerals might cause such effectswith respect to impurities or oversized particles. Angle dependenteffects can not be excluded, in case of lamellar minerals.SACHTOPERSE AB is fully synthetic, based on globular, precipitatedbarium sulfate, which is optimized with the decade longexperience of Sachtleben with this kind of products.Although the beneficial effects of SACHTOPERSE AB can beexploited in any polymer, use in highly transparent and glossypolyester films demonstrates the potential of SACHTOPERSE AB.Enhanced optical film properties2520StandardSACHTOPERSE AB130120HAZE [%]105GLOSS [%]110908000 500 10001500 2000700 500 10001500 2000ADDITIVE CONCENTRATION [ppm]ADDITIVE CONCENTRATION [ppm]18
The gradesDepending on the required film thickness SACHTOPERSE ABis available in different particle sizes for thin (AB-TS), medium(AB-TM) or standard films (AB-TL).Properties and benefits• Specialty coating• Excellent dispersibility for optimized process abilityand improved filter life time• Optimized compatibility leading to improvedadhesion between particle and film polymer• Pure synthetic and inert barium sulfate• Adjusted particle size• Creation of a uniform hill-valley-structure of film surface• Nearly identical refractive index as film polymers• Minimized light scattering• Suitable for food packaging• No reaction with polymersSACHTOPERSE AB-TS SACHTOPERSE AB-TM SACHTOPERSE AB-TLAppearance powder, odor neutral, powder, odor neutral, powder, odor neutral,insoluble non-toxic insoluble non-toxic insoluble non-toxicParticle size [µm] 0.7 1.4 4.0BaSO 4content [%] 96.5 96.5 96.5Refractive index 1.6 1.6 1.619
