... or to the rubber curing process occurring to an excessive degree as the rubber contacts the presumably hot mold. If the mold temperature is too hot during filling, the rubber becomes more viscous as it begins to cure and, hence, more resistant to uniform flow, which can result in voids. These voids will serve...
