Thermoplastic Elastomer Infill Synthetic Turf

Synthetic – turf or Astroturf, is a grass-like man-made surface manufactured from synthetic polymers. It is most used for sports field and in residential area where natural grass is difficult to grow. Synthetic turf consist three basic components – grass filaments, Infill and backing. Grass filaments require softness and impact strength. Through several generations, grass filaments developed from initially nylon, polypropylene and now from polyethylene. Crumb rubber is used as infill material which contains toxic chemicals present in tyre. Some of the drawbacks of these materials can be solved by modifications in materials like by introduction of TPE –thermoplastic elastomer, which has been presented in this paper.
