Abstract

Reclaim rubber is obtained from vulcanized rubber by subjecting a mass of the rubber to mechanical working applying highly intensive impact forces to the mass. The process is relatively energy efficient and therefore produces reclaim rubber at relatively low cost. It also mitigates the objectionable smell associated with known reclaim rubber products. The process can be used with the addition of small amounts (usually of the order of 1% to 2% by weight) of various chemicals known to retard cure rates in rubber, but it has been shown to be efficient on a production basis to operate without the addition of, or dependence on, any added chemicals.
