Compared with natural grass, modern synthetic turf systems distinguish themselves in part due to their cost-effectiveness. Durable and easy to clean, they can be played on all year round. In order to further improve their appearance, feel and wear protection, Polytan has developed the versatile LigaGrass Pro CoolPlus. Owing to these and other positive properties, it can be described as another major step in the development of textured turf systems. The system is particularly suitable for sports facilities which are used intensively, such as publicly accessible communal facilities.
New fibre geometry makes for a more pleasant look and feel. The filaments are not rectangular – as is currently the case for textured (crimped) turf – but have a triangular cross-section. This creates flexible ends that, despite texturing, are soft to the touch. Moreover, the thickness and width of the fibres was increased compared to the predecessor LigaGrass. Both of these factors protect against wear and tear and provide a dense, uniform playing surface. The ability to now uniformly texture and bulk up even thicker filaments, which do not have a rectangular cross-section, is down to the new Polytan PreciTex technology.
Another special feature of LigaGrass Pro CoolPlus are its two-tone fibres. These create a rich shade of green and so make the synthetic turf appear more natural. This is the first crimped Polytan synthetic turf system to offer this BiColour design. Another advantage is the CoolPlus function, which has been tried and tested for several years now. Pigments on the filaments reflect sunlight, thus delaying and reducing the potential increase of temperature on the playing field. The larger reflective surface on textured synthetic turf systems contributes to this effect.
The LigaGrass Pro CoolPlus turf system has been available since November 2014 with a sand-rubber filling and as a sand-filled variant and meets all the significant tests and certifications required by EN, DIN and RAL as well as FIFA and FIH (International Hockey Federation).
Modern artificial turf yarns as high-tech product
The heart of every artificial turf from Polytan is its fibers or filaments from a high-quality PE-polymer formulation. Their properties, which may vary in product line and direction, can be influenced by material commodity, formulation, design, filament thickness and production technology.
The patented ENTANGLEMENT technology, where the molecular chains are additionally connected with each other, cares for an improved abrasion- and UV- resistance. Furthermore the Cool Plus function arranges that a playing field will not be heated up on warm days. In this case special pigments on the filament surface reflect a part of the infrared solar radiation. The so-called stick-slip effect on the skin prevents the "SharkSkin" technology – in the process the surface of the filament receives a micro-roughness. The result are turf fibers, which do not stick to the skin, but glide like natural grass over it. Related to the design of the fibers, it has been the development of a diamond-shaped cross-section, which makes the filament particularly stable and durable today and convinces with excellent shock absorption values and a lower susceptibility to fiber breakage or splicing.

For many people, sport and exercise are part of their everyday lives and key to a long and healthy life. However, many others tend to be sedentary, and the level of daily physical activity among children is also steadily decreasing. It is the constant state of change our world is in, especially technical progress, that is the cause of this problem. Yet this process is ...
