Beschreibung
Zusammenfassung:	A particulate, relatively free-flowing rubber processing aid capable of imparting release properties and improved flow characteristics to rubber during compounding and molding of the rubber, comprises petrolatum and particulate clay in proportions of petrolatum to clay of from about 1:4 to about 4:1. The amount of processing aid which is effective to impart improved release and flow properties is from about 0.1 to about 5 weight percent of the total rubber compound.
