The Benefits of PU Backing
PU stands for Polyurethane. A PU coating is used on some of our artificial grasses and is a more recent addition to the Grass 247 artificial grass range. It offers some points of difference from the more ubiquitous latex backing found on most artificial grasses and some advantages too.
PU is a polymer. Other polymers include nylon, silicone, polyethylene and polypropylene. It’s basically a substitute for rubber and helps provide a very strong, durable and stable substrate for the blades of artificial grass that are stitched into it. Latex, on the other hand, is a natural rubber.
Why choose a PU backing?PU is particularly suited to pets. Some pets can have an allergy to latex which is a more commonly used backing. So, there’s one good reason right there. If you are concerned about possible allergies, then opt for one of our PU coated backings over pure latex every time.
PU is also more resistant to pet urine, which tends to burn patches into natural grass. So again, whether it’s a latex backing or PU coated, both provide this advantage and have excellent drainage, however, where PU scores over latex is in its ability to eliminate odours. Over time, latex can harbour a pet’s urine odour, particularly if it’s not rained for some time, or the grass hasn’t been hosed down. PU on the other hand is more resistant to moisture absorption and diminishes this issue significantly.
We do still recommend, for hygiene reasons, that your grass is occasionally cleaned with a diluted disinfectant if you have pets and we sell products specifically for this purpose..
Temperature resistance
PU is also very temperature stable, meaning it will expand and contract to a lesser degree in very hot or cold weather, thus retaining a better fit for your grass, all day, every day. Latex does the same job, but the addition of a PU coating means it’s just that little bit better at resisting the great British weather and its vastly-ranging temperatures.
PU is more durable
A PU coating also has the benefit of added durability. Although any artificial grass will last for many, many years, a PU coated backing will out perform a purely latex backed grass by a good margin.
It has a natural corrosion resistant quality that helps protects against everything nature throws at it.
A PU coated backing also has an additional softness and smoothness for easier and more flexible installation.
