Abstract

A composition for coating the innermost carcase ply of a tubeless tyre (see Group XXXIV) comprises a mixture of Butyl rubber reclaim in an amount sufficient to provide from 3 to 20 parts of Butyl rubber hydrocarbon, with 100 parts of natural and/or GR-S rubber hydrocarbon, together with the usual compounding ingredients. The Specification gives examples of such compositions with different amounts of reclaimed Butyl rubber hydrocarbon in the range 2,37 parts to 14,25 parts all based on the following control stock:- .Smoked Sheet Natural Rubber.10,00.Parts .Whole tyre reclaim.50,00.Parts .Semi-reinforcing Furnace Black.20,00.Parts .Stearic Acid.2,00.Parts .Pine Tar.3,00.Parts .Anti-oxidant.1,00.Parts .Zinc Oxide.5,00.Parts .Benzothiazyl disulphide.0,75.Parts .Sulphur.3,50.Parts ..185,25.Parts Specification 726,006 and U.S.A. Specification 2,587,428 are referred to.
