Pile height, infill type, and yarn type all play significant roles in reducing skin abrasion.

General Characteristics Dow Products Qualities Results
Yarn Type

Skin abrasion is a direct result from skin and surface friction. Consequently, similarly to the latter, the yarn type, the choice of resin used, the shape and geometry of the yarn will play a significant role with regards to skin abrasion.

The softness of the material is a decisive characteristic in this context. For that reason, polyethylene solutions are particularly suitable and increasingly used in this application, where other resins, such as polypropylene, are much too harsh and hence too abrasive for the skin.

Low skin friction and long durability for play consistency
Pile Height

Skin abrasion is a direct result of skin friction on the turf surface. Pile hight has a key role in achieving low friction parameters. Piles should have sufficiently long blades of grass to cover the infill material to diminish the risk of skin/surface friction and ultimately skin abrasion.

Your Dow product choice for yarn type will contribute to desired pile height.
Infill Type

Skin abrasion is a direct result of skin friction on the turf surface. A high degree of elastomers is needed in the infill to achieve a degree of softness which reduces the risk of skin abrasion.

A good balance between rubber and sand infill is key as sand on its own is very abrasive to skin and the yarn.

Extreme temperatures can also effect and change the properties of the infill, making it too soft at high temperatures and harder at lower temperatures, thus increasing the risk of skin abrasion.
