Automobile tires are composed of outer tires, inner tubes and pads, wherein the outer tires include tire top, tread, sidewall and bead. The bead wire ring is composed of a wire ring and a filler, so that the tire can be tightly fixed on the rim and withstand the interaction force among the tire and the rim; the cushion tape is placed on the part where the inner tube and the rim are in contact to protect the The inner tube is not subject to wear by the rim assembly and requires good heat resistance. The editor today shares with you four reference formulas of tire bead rubber and pad rubber mixed with reclaimed rubber.

Tread reclaimed rubber processed from tire tread rubber powder as raw material has high effective rubber hydrocarbon content and good elasticity. It is used in the production of different parts of automobile tire casings, which can better ensure product performance and service life. In actual production, tire reclaimed rubber can not only be used in car cushion rubber, bead ring rubber, but also can be added to treads, sidewalls and even inner tubes. Later, Xiaobian will continue to share with you the use of tire reclaimed rubber in car tires. application tips and practical reference recipes.
