SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs SYNPaws Play Roll-Bar Artificial Grass: which is safer?

Where these two actually differ

• We flag VOC off-gassing from polyurethane or latex adhesive, Polypropylene UV degradation and microplastic shedding, Backing adhesive failure and fiber separation and Infill contamination (if rubber granules used) on the AstroTurf and not on the SYNLawn.
• We flag Undisclosed water-resistant/stain-resistant coating chemistry, Microplastics and synthetic fiber shedding, Volatile organic compound (VOC) off-gassing during installation and Leaching from polyethylene backing and adhesives into soil or water on the SYNLawn and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the SYNLawn is polyethylene synthetic grass with undisclosed water/stain-resistant coating, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the AstroTurf is the one to buy.
• We are less certain about the SYNLawn grade, at 35% confidence against 72%, because it discloses less.
