Abstract
A very soft polyurethane composition is provided having a low level of an aromatic phosphate or phosphonate plasticizer that will perform well as a self-sealing liner to flat-proof pneumatic tires, and will withstand the high temperatures of the tire retread process and still be functional. The liner is produced by a method of meter-mixing an isocyanate component and a high molecular weight polyol component system that can be poured directly into the tire to be lined as it is being rotated to spread the material uniformly in the tire until it sets up and will not cold flow. Also, the meter-mixed liner material can be poured on a flat surface of release paper to form sheet stock that can be cut into strips and then applied to the inner lining of the tire at a later time.
