Sports surfaces as artificial turf or indoor sports floors have seen rapid growth in recent years due to the improved player safety and game consistency provided by such surfaces. A big portion of such performance criteria are provided by the shock absorbency components integrated into such floorings in the form of granular infill or shock pads/underlays.
The selection of such components obviously is a key factor for success. Dow has recently conducted work to develop performance models for different foam systems in order to provide appropriate selection tools. Different foam compositions were screened for their performance in stress response, elastic recovery and creep resistance as shockpads using lab tests in compression along with FQC (FIFA Quality Concept) tests both on the foams and on an artificial turf system. The results of this work provide evidence that shockpads highly influence the energy absorption property of an artificial surface. Sports surfaces with no or non-shock absorbing infill can be designed. Based on raw material selection and foam characteristics, desired performance characteristics can be predicted.
Polyurethane binders and polyolefin solutions are central to Dow’s shock absorption materials. These materials can be blended and adjusted to provide the right amount of give to address the specific needs of the players.
ENHANCER™ Sport Polyurethane Systems and VORAMER™ Polyurethane Binders are central to Dow’s shock absorption materials. By blending them, their composition can be tailored for optimal performance, providing precisely the right amount of give to meet the specific needs of the players.
Dow Products for Shock Absorption:
ENHANCER™ Sport Polyurethane Systems help your turf withstand tough wear and tear, with strong tuft bind and dimensional stability, even in wet conditions. A backing made with ENHANCER Sport is the ideal solution for applications where performance and durability are important.
VORAMER™ Polyurethane Binders are produced with quality aromatic isocyanates such as MDI, MDI/TDI, and TDI and can be used in a variety of applications, bonding together different types of shredding materials such as rubber and flexible polyurethane foams. VORAMER binders can be used also as one component coating films for SBR granules (recycled tires), allowing perfect adhesion to the substrate with a very fast, simple and economic process. VORAMER binders based on Dow’s prepolymer technology and experience, are available in colorless, red and green versions.
