Disclosed is an infill for an artificial turf field, the infill comprising: from about 40 wt. % to about 60 wt. % of a polyvinyl chloride resin; from about 5 wt. % to about 30 wt. % of a plasticizer derived from a naturally occurring source; from about 2 wt. % to about 10 wt. % of a reflective pigment; from about 0.01 wt. % to about 0.1 wt. % of a blowing agent; and from about 5 wt. % to about 30 wt. % of a filler. The infill is pelletized and maintains the temperature of an artificial turf field, when disposed throughout the artificial turf field, at a temperature about 15° F. to about 25° F. less than a temperature of a comparative artificial turf under substantially similar ambient and environmental conditions, wherein a comparative infill of the comparative artificial turf consists essentially of crumbed rubber infill.
