TIRE TREAD COMPRISING A CROSSLINKING SYSTEM BASED ON ORGANIC PEROXIDE
United States Patent Application 20210213781 A1 · Filed: 04/25/2019 · Published: 07/15/2021

A tire tread comprises a rubber composition based on at least from 50 to 100 phr of a first diene elastomer, the first diene elastomer being a polybutadiene-based elastomer, modified with a functional group capable of interacting with silica as reinforcing filler; optionally from 0 to 50 phr of a second diene elastomer; at least 20 phr of carbon black; less than 40 phr of silica as reinforcing filler; a coupling agent; a plasticizing system comprising a plasticizing resin exhibiting a glass transition temperature of greater than 20° C.; and a crosslinking system based on organic peroxide; the total content of the first diene elastomer and of the second diene elastomer in the composition being within a range extending from 80 to 100 phr.

Assignee:

COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN (Clermont-Ferrand, FR)

This is a very interesting patent application.  The tire tread being covered is based on peroxide cross-linking, with almost no sulfur.  Plus, the plasticizing resin is used at about 70phr in the examples, the silica use is in the range of 40phr in the examples (relatively low for most tire patents today).
