The present invention describes a reinforcing filler for rubber comprising the synergistic combination of precipitated silica with a pore structure defined by a maximum between 25 nm and 35 nm, a total pore volume between 1.3 cm/g and 1.6 cm/g, and a compression factor between 1.3 10and 2.3 10MPa, and at least one crystalline alkaline silicate corresponding to the general formula of the crystalline alkaline silicates, said crystalline alkaline silicate being swelled and/or layered in the presence of an organic cationic compound in the form of ammonium salt of the +NRtype according to the formula [CHN(CH)]. The rubber formulation obtained by this reinforcing filler composition does present a great reduction of energy dissipated in the tread without compromising the abrasion resistance and elastic modulus properties.

Reinforcing filler for rubber

A process for the additivation of synthetic fibers, artificial fibers and polymers conferring special properties to them, the process comprising the following steps: the encapsulation of an additive in the pores of a porous material; the incorporation of particles of the porous material (capsules) into the polymer matrix of the fiber; and spinning of the fiber; the capsule withstanding the temperatures and other conditions of the different manufacturing processes which the fibers might undergo and the introduction of the additive into the polymer matrix thereof, characterised in that the porous material is a metal oxide, a zeolite, an aluminophosphate, clay, a carbon material, a hybrid organic-inorganic material or a porous polymer. The invention is an improvement in the additivation process of fibers and polymers in terms of the nature of the capsules used, the increase in the storage capacity of additives thereof, the process of incorporating the capsules into the polymer matrix of the fibers and the fact that the present invention refers to an industrial process.
