ABSTRACT:
This disclosure relates to a sealant material to be primarily used in pneumatic tires to seal punctures made by external objects, such as nails. The sealant may be a single layer or a laminate of sealant layer and covered layers. The sealant layer contains a material that is at least partially degraded by irradiation or heat in the presence of a peroxide. The laminate may be in sheet or strip form with various cross-sectional shapes. The layers in the laminate comprise rubber compounds, some of which may contain agents which either assist or retard cure by irradiation so that the layers will have different physical characteristics during the manufacture of end products containing the laminate. The laminate may be cured by any known method, either irradiation or thermal, after its assembly into the final product.
