Filled Resins

AARO-FILL® compounds are manufactured using recycled polypropylene, blended with talc, calcium and other performance enhancing fillers. AARO-FILL® compounds are available in standard grades and can be also be customized using colorants and other functional additives. Standard grades are outlined below.
