Nylon is very strong and produces the stiffest blades. That means it holds its original shape, even under hard athletic play or other types of high foot traffic. Nylon also stands up to high temperatures without losing stability or melting. These attributes make nylon the most expensive artificial grass material.
Nylon might look like natural grass, but it does not respond the same as the real thing. It is used to produce secondary thatch in high-end synthetic turf products and also for putting greens.
