Abstract
Un producto polimérico con al menos una superficie sujeta a desgaste o abrasión, en donde al menos una porción de este producto incluye microcápsulas de una sustancia indicadora que se libera para indicar que se ha alcanzado un estado de desgaste. La sustancia indicadora microencapsulada puede ser una fragancia o un colorante. La porción o zona indicadora puede ser una capa o una fina lámina de microcápsulas de caucho o del material polimérico que constituya el cuerpo del producto. Puede haber más de una capa o zona indicadora en el producto. Las diversas zonas pueden contener diferentes fragancias o colorantes, que pueden proporcionar una indicación progresiva del estado de uso.
