Abstract

"PNEUMáTICO". Pneumático que possui um vértice, dois flancos e dois frisos, uma armadura de carcaça com primeiros reforços dispostos de modo adjacente, alinhados circunferencialmente em pelo menos um alinhamento circunferencial a partir de pelo menos um dos ditos frisos na direção de um dos ditos flancos e ancorada no dito friso, e uma armadura de vértice, o dito friso possuindo uma zona de ancoragem que permite a retenção da armadura de carcaça e compreendendo pelo menos um segundo reforço orientado circunferencialmente que opera junto com uma porção adjacente da armadura de carcaça por intermédio de uma mistura borrachosa de ancoragem em contato com o segundo reforço e com os segmentos adjacentes dos primeiros reforços, caracterizado pelo fato de que a dita mistura borrachosa de ancoragem tem um módulo de elasticidade a uma deformação de 10 % compreendido entre 10 e 20 MPa e pelo fato de que a dita mistura borrachosa de ancoragem compreende pelo menos um elastómero sintético compreendido no grupo dos SBR e dos polibutadienos com uma proporção total de elastómero sintético superior a 50% do peso total dos elastómeros.
