The most important constituent of Vredestein inner tubes is butyl, a synthetic rubber with a very low gas permeability. This means that the inner tube retains its required pressure longer. Vredestein inner tubes are autoclave tubes, produced according to the Unitube system. This means that a Vredestein inner tube is suitable for various sizes of outer tyre. Autoclave inner tubes are easily fitted thanks to a pre applied thin layer of talcum powder on the outside of the inner tube.
