Poly-Turf

Poly-Turf was a brand of artificial turf in the early 1970s, manufactured by American Biltrite of Wellesley, Massachusetts. It was the first specifically designed for American football, with a patented layered structure which included a "shock pad" between the artificial grass and the asphalt sub-surface. It used polypropylene for its artificial grass blades, rather than the nylon used in AstroTurf and 3M's Tartan Turf.
