Abstract
Tire components comprising a microencapsulated reactant and a reaction facilitator are provided. These components have the ability to resist crack propagation and to self-repair cracks that form within the tire component matrix.
Claims3
A tire component comprising:
- (1) a microencapsulated reactant and (2) a reaction facilitator.
A process for forming tire components having improved durability, the process comprising the steps of:
- providing a tire component matrix;
- encapsulating a reactant to form microcapsules;
- selecting a reaction facilitator capable of facilitating the polymerization of the reactant;
- and
- adding the microcapsules and the reaction facilitator to the tire component matrix.
2 more elements
A banded tire having a band element comprising:
