SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs ALLGREEN Star Grass 35 Emerald Green/Olive Green Indoor/Outdoor Turf 15 ft.: 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 Global Syn-Turf.
• We flag PFAS in backing and adhesive layers, Microplastic shedding from fiber degradation, Bacterial and mold growth in wet backing and Volatile organic compound (VOC) off-gassing on the Global Syn-Turf and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the Global Syn-Turf is Synthetic polypropylene or polyethylene turf with unknown backing/adhesive, which is most of the difference in these two grades.
• The gap is 35 points, wide enough that this is not a close call, and the AstroTurf is the one to buy.
• We are less certain about the Global Syn-Turf grade, at 35% confidence against 72%, because it discloses less.
