I found a artificial turf company online called Global syn Turf. I was very impressed with their website in the amount of information that they give you. One of the things I found the most interesting was their artificial grass technology and all of the unique delayed design that they invented. If you're shopping for artificial turf a lot of people think that nylon fibers are the way to go however polyethylene is the fibers you want. Also important is the turf construction factors like density, fiber shape, filament type, Etc. all of these things combined will determine how well the artificial grass will do and withstand the elements. I recommend you read this article on Global Syn Turf about their blade Technologies and nylon vs. polypropylene Synthetic Turf fibers. Global Syn Turf has invented different blade shapes such as C shape blade, Diamond blade, S blade, double w Blade, s blade shape, 7 stem blade, stem blade, U blade, V-shaped blade, and W shaped blade. This is quite an impressive list of design in the artificial turf industry.  One of the more interesting blade Design's is the hollow blade which allows moisture to get into the blade and create a cooler artificial turf. This is especially effective when you have kids or pets play on the artificial turf and you live in a warm climate. Bottom line I recommend everyone go to this website and check out all the information and don't forget to ask for some free samples to be sent to your home at no cost.
