SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs Shaw Philadelphia Launch 54743 Indoor Outdoor Turf Carpet: 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 Shaw Sports Turf.
• We flag Flame retardants (brominated or phosphate-based), Volatile organic compounds (VOCs) from backing adhesives and treatments, Microplastics and fiber fragmentation and Leachables from backing or adhesive (phthalates, additives) on the Shaw Sports Turf and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the Shaw Sports Turf is synthetic turf with backing and stain/water 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 Shaw Sports Turf grade, at 35% confidence against 72%, because it discloses less.
