Poly-Turf

Poly-Turf was a brand of artificial turf, 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.

In the late 1960s, the natural grass surface at the Orange Bowl in Miami was commonly in poor condition, primarily due to heavy usage; 34 games were scheduled there during the 1968 football season.

Poly-Turf was installed at the City of Miami-owned stadium in 1970, and utilized for six seasons. The stadium was used for both college and professional football, primarily by the University of Miami Hurricanes and the Miami Dolphins of the NFL. It also hosted the eponymous New Year's Day college bowl game, Super Bowl games, and high school football.

The University of Nebraska Cornhuskers won the first three Orange Bowl games played on Poly-Turf, which included two national championships. The first Super Bowl played on artificial turf was played on Poly-Turf in the Orange Bowl in January 1971, when the Baltimore Colts defeated the Dallas Cowboys 16-13 in Super Bowl V. The next Super Bowl at the stadium was the final game played on Poly-Turf in Miami; Super Bowl X in January 1976. Its flaws received additional media exposure the week prior to the game, and Dolphins receiver Nat Moore documented them in a local article.
