Higher doses of the organic component, in particular, will notincrease the thermal stability of the polymer, whether used incombination with SACHTOTEC MD 300 or alone. The benefits ofSACHTOTEC MD 300 can be exploited in two ways - it is possible,on the one hand, to reduce input of an organic metal deactivatorif, for example, problems with fogging are encountered; it is alsopossible, on the other hand, to increase service-life to a previouslyunknown level, and thus meet the challenges to which futuresystems will be exposed.Additional effect ofSACHTOTEC MD 300MD: organic metal deactivator: hindered phenolCu source: copper plateSTORAGE TIME [HOURS AT 140˚ C]30002500200015001000Additional effect ofSACHTOTEC MD3000.2 % MD 0.5 % MD 0.2 % MD0.5 SACHTOTECMD 3000.5 % MD0.5 % SACHTOTECMD 300TEMPERATURE °CThe beneficial effects of SACHTOTEC MD 300 have been demonstratedacross a large range of temperatures; it must be assumedthat the performance of this product will be poorer at very hightemperatures, (decomposition temperature of polymer), however.SACHTOTEC MD 300Performance inpolypropyleNEEXPOSURE TIME [HOURS]800070006000500040003000200010000120 130No MD0.5% MD0.5 MD/0.5% SACHTOTEC MD 300MD: organic metal deactivator: hindered phenolCU source: 50 ppm Cu stearate • Filler: 60 % Mg (OH) 2140 150TEMPERATURE °CSACHTOTEC MD 300AppearanceSurface treatmentwhite powderorganic dispersantZinc sulfide content [%] approx. 90Density [g/ml] approx. 3.7Volatiles (105º) [%] approx. 0.5Specific surface area [m 2 /g] > 30Primary crystallite size (Scherrer) [nm] approx. 1017
