Abstract:
1. A pellet formed by a method comprising the steps of: dispersing from about 30% to about 95% by weight of thermoset rubber particles into a carrier resin to form a plastic compound, weight percent based on the total weight of the plastic compound, the carrier resin comprising an olefin block copolymer, wherein the olefin block copolymer comprises an ethylene-1-octene block copolymer and is present in the plastic compound in an amount of from about 5% to about 70% by weight based on the total weight of the plastic compound; extruding the plastic compound through a die having at least one die hole to form at least one extrudate filament; cutting the at least one extrudate filament to a predetermined length to form at least one pellet; conveying the at least one pellet in water to a separator/centrifugal dryer, the water having a temperature of about 170° F. or greater; and separating the at least one pellet from the water in the separator/centrifugal dryer, the at least one pellet substantially dry upon removal from the separator/centrifugal dryer, the pelletized plastic compound having a flex modulus of less than about 20,000 pounds per square inch (psi).
