Title
(EN) NEW SILICA, PROCESS FOR ITS PREPARATION AND ITS USES
(FR) NOUVELLE SILICE, SON PROCÉDÉ DE PRÉPARATION ET SES UTILISATIONS
Abstract
(EN) A precipitated silica characterised by low silanol ratio. The precipitated silica is in particularly suitable for use as filler in elastomeric mixtures.
(FR) Silice précipitée caractérisée par un faible taux de silanol. La silice précipitée est particulièrement appropriée pour être utilisée comme charge dans des mélanges élastomères.
