  • Patent number: 5603366
    Abstract: A precure tread for a tire has surface grooves facing a tread face, rear grooves facing a crown portion of a base tire, and a passage for communication between the rear grooves to atmosphere. The groove bottom of the rear grooves is located at a higher level than a groove bottom of the surface groove in the radial direction. The tire durability can be considerably improved when this precure tread is applied to a new tire or a retreaded tire.

  • Patent number: 4124573
    Abstract: A soft polyurethane elastomer containing isocyanurate ring prepared by reacting polyoxypropylene polyol having an OH equivalent molecular weight of about 500-3,000, and a functionality of about 2-5, and polyisocyanate compound in the presence of tertiary amine catalyst, and if desired further combined with organic tin catalyst. This process is advantageous in facilitation of material control during curing reaction, low exothermicity and high thermal stability of the resulting polymer. Further the properties of the polymer are improved by using ethyleneoxide addition polyoxypropylene polyol instead of the above polymer and a specific tertiary amine as a catalyst. The elastomer thus prepared is significantly suitable for tire filling material.

  • Patent number: 4062825
    Abstract: A polyurethane composition having high tear strength has been produced by mixing homogeneously 20 to 50 parts by weight of finely divided acidic silica particles, 100 parts by weight of isocyanate-terminated prepolymer and appropriate parts of curative, and curing the mixture in a manner well known in the prior art, where the ratio (l/d) of average chain distance (l) between adjacent crosslinking points of the cured polyurethane chains to average size (d) of finely divided silica particles is in the range of from 2.5 to 20.

  • Patent number: 4053446
    Abstract: Polydiene polyurethanes having high tear strength are obtained by using polydiene glycols, prepared with use of lithium-based catalyst, having a number average molecular weight of 1,000 to 5,000 and functionality of 1.8 - 2.1, diisocyanates and chain-extending agents, and by controlling chemical cross-link density being 4 .times. 10.sup.-5 mole/cc and less. When the chemical cross-link density is within the above range, elongation and tensile strength in addition to tear strength of the polyurethane are improved significantly. Furthermore, when 10 - 50 parts by weight of the specified carbon black are added to 100 parts by weight of the mixture of the prepolymer, the chain-extending agent and the additive prior to curing the prepolymer, these mechanical properties of the polyurethane are improved further.
