Artificial turf is made from polyethylene and polypropylene.
It is treated and tufted to a permeable backing. Specially engineered equipment places each individual grass fiber in the backing. The infill is made from silica sand and ground rubber which surround and hold the fibers like the earth holds grass. The artificial turf both looks and feels like real grass. A new company, Trakus Inc. has developed a small device, placed in a hockey or football player's helmet, which sends data to a software intensive system that computes the information throughout the course of the game.
