  • PRECIPITATED SILICA AND PROCESS FOR ITS MANUFACTURE
    Publication number: 20250026649
    Abstract: A precipitated silica having large particle size for use in tire applications. In particular, a precipitated silica characterised by a CTAB surface area SCTAB equal to or greater than 160 m2/g; a median particle size d50, measured by centrifugal sedimentation, such that ? "\[LeftBracketingBar]" d ? 50 ? ? "\[LeftBracketingBar]" > 25000 / ? "\[LeftBracketingBar]" S C ? T ? A ? B ? "\[RightBracketingBar]" ( I ) wherein |d50| represents the numerical value of the median particle size d50 measured by centrifugal sedimentation and expressed in nm and |SCTAB| represents the numerical value of the CTAB surface area SCTAB expressed in m2/g; and an aluminium content not exceeding 4500 ppm.
