Beschreibung
Zusammenfassung:	Disclosed is an additive for a plastic, comprising fine particles obtained by calcination and slaking of a dolomite which exhibits two endothermic peaks in the differential thermal analysis, said fine particles containing calcium carbonate, magnesium carbonate, magnesium oxide, calcium hydroxide and magnesium hydroxide as main chemical components and also containing an ignition loss component in an amount of 10 to 40% by weight based on the weight of said fine particles. A plastic hating hydrogen chloride scavenging properties and antimicrobial properties imparted by incorporating the additive for a plastic is also disclosed.
