Document Type and Number:
Japanese Patent JP4755326
Kind Code:
B2
Abstract:
Use is claimed of elastomeric mixtures, for internally filling the lower zones of pneumatic tires, based on natural rubber or synthetic polyisoprene with mostly cis-1,4 links; optionally another elastomeric diene, in the case of blending the natural rubber or synthetic polyisoprene making up the majority of the mixture; and a reinforcing filler. Use is claimed of elastomeric mixtures, for internally filling the lower zones of pneumatic tires, based on natural rubber or synthetic polyisoprene with mostly cis-1,4 links; optionally another elastomeric diene, in the case of cutting the natural rubber or synthetic polyisoprene making up the majority of the mixture; and a reinforcing filler comprising: i) white filler of the silica and/or alumina type with surface SiOH and/or AlOH functions selected from precipitated silica, silica ash, aluminas or aluminosilicates; or better carbon blacks modified during or after synthesis so as to cover at least part of the surface with SiOH and/or AlOH functions, with specific surface area = 30-260 m<2>g<-1> used in content of 15-40 pce; or ii) by a blend of carbon black with specific surface area = 30-160 m<2>g<-1> and a white filler as in i) in which the global filler content of 15-50 pce and the white filler content is greater than or equal to the carbon black content (in pce) - 5.
