SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs Emerald Green Artificial Grass Turf Rug: 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 TrafficMaster.
• We flag Volatile organic compounds (VOCs) from water/stain-resistant treatment, Fiber shedding and microplastic particle release, Mold and bacterial growth in wet backing and Polypropylene degradation and leaching under heat on the TrafficMaster and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the TrafficMaster is Polypropylene turf with unknown water/stain-resistant treatment, 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 TrafficMaster grade, at 45% confidence against 72%, because it discloses less.
