Monofilament synthetic grass is the most simple version available. It is made from a synthetic plastic, typically Polyethylene, that is shaped into single blades. A strong plastic backing material cements these blades in place when the law is installed. This monofilament design is cost effective and can easily resemble the longer, darker natural grasses.
Fibrillated synthetic grass is also made from Polyethylene but has one key difference: the blades, instead of being one blade shape, are slit in the middle, allowing the grass blades to compress in a honeycomb style. Manufacturers often make fibrillated grasses thicker than monofilament versions to give room for the slit. These grasses are used in sporting areas or in landscaping where users want the effect of a Bermuda-type grass.
Bent artificial grass products have single blades of grass attached to a base like monofilaments, but these blades are slightly rolled and can simulate bent blades of grass, usually for a shorter landscaping or putting grass. The bent blades are typically made out of Polypropylene instead of Polyethylene and are often much shorter than the straight monofilaments.
Manufacturers use nylon when creating the backing for many kinds of artificial grass, but the nylon itself can also be used to imitate grass. Nylon grass is very short, rarely over 2.5 inches long, and buyers often use it for putting greens or field hockey surfaces.
