摘要： A method for producing a rubber composition includes: applying a compression process to a fumed silica having a BET specific surface area of 200 m2/g or more to obtain a compressed fumed silica having a tap density of 200 g/L or more; and kneading the compressed fumed silica and diene rubber. A fumed silica for rubber composition is obtained by a surface treatment with a mercapto-thiocarboxylate oligomer, and has a tap density of 200 g/L or more and a BET specific surface area of 200 m2/g or more. A rubber composition contains a compressed fumed silica having a tap density of 200 g/L or more and a BET specific surface area of 200 m2/g or more; a natural rubber; and a mercapto-thiocarboxylate oligomer.

摘要： The present disclosure provides an all-steel tire with 100% definite elongations of an upper tread and a lower tread being interrelated to each other. The all-steel tire of the present disclosure includes a lower tread rubber layer B and an upper tread rubber layer A. Through repeated multiple experiments of the applicant, when a ratio of stresses at 100% definite elongation of the upper tread rubber layer A to the lower tread rubber layer B is (0.7-0.8):1, and the 100% stress at definite elongation of the lower tread rubber layer B is 3.2-5.5 Mpa, it can be ensured that after any tread of the tire is subjected to performance adjustment, the performance balance of the whole tire crown is continuously maintained, so that no new problem is generated after the tread performance of the all-steel radial tire is improved.

摘要： Spreadable granules as infill granules for grass and artificial turf fields are proposed, which granules have a polymer matrix with a percentage between 10% by mass and 100% by mass of at least one biodegradable polymer and at least one filler from the group of natural fillers, embedded in the polymer matrix with the at least one biodegradable polymer. The invention provides for the spreadable granules to have at least one filler from the group including comminuted fruit kernels. In addition, the invention relates to the use of such spreadable granules as infill granules for grass and artificial turf fields, as a spacer material for the storage of construction materials, such as, e.g., floor covering materials, and as grit for road maintenance in winter.

摘要： Provided are a modified cellulose fiber-containing rubber composition and rubber composition for tires that are allowed to simultaneously achieve excellent rigidity, excellent tensile properties, and low energy loss by improving the dispersibility of the cellulose fiber in rubber, as well as a pneumatic tire formed from the rubber composition, having excellent handling stability, excellent rolling resistance properties, and excellent durability. The present invention relates to a modified cellulose fiber-containing rubber composition containing: a modified cellulose fiber (A) obtained by adding a C15 or higher cyclic polybasic acid anhydride (a) containing a hydrophobic group to a cellulose fiber through esterification; a dispersing polymer (B) having a softening point of 135° C. or lower; and a rubber component (C).
