摘要：
A carbon black filler for crosslinkable elastomer composition having a content of impurity metals of not more than 300 ppm and a pH value of 5.0 to 11.0. The filler can be obtained by subjecting a starting carbon black filler to extraction treatment with an acid to reduce a content of impurity metals of the filler and then alkali treatment with an alkali to neutralize a remaining acid. The filler does not cause a crosslinking failure even when added to an elastomer composition and can provide an elastomer molded article suitable as a very clean sealing material for semi-conductor production apparatuses.
