Polypropylene
Polypropylene is the least expensive material. It has a finer texture, so it is the most realistic looking artificial grass. However, it is also the least durable, least resilient, and least heat-resistant. Under prolonged heat, the blades can become deformed.
Nonetheless, this material is popular for home putting greens because it has a softer roll. And because it is lightweight and flexible as well as affordable, it is also popular with people who want to use artificial turf grass for creative indoor or outdoor projects.
Polyethylene
This material produces the most life-like grass. Not surprisingly, it is a popular choice for home owners who want to replace their natural grass lawn with a synthetic turf product without sacrificing aesthetics. Polyethylene is vibrantly green, soft to the touch, yet very resilient. It is especially durable when combined with nylon as a secondary thatch. That makes it a good choice for athletic fields, too.
Artificial grass made from polyethylene is simple to maintain, as it requires only the occasional raking or brushing. This keeps the surface free of debris and “fluffs” the blades, ensuring the blades and infill retain their cushion and bounce.
