SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs ALLGREEN Pet Turf Emerald Green/Olive Green Indoor/Outdoor Turf 15 ft. Wide: 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 Backing adhesive leaching, Mold and bacterial growth in backing, Microplastic shedding and Heavy metal pigments in synthetic dyes on the Global Syn-Turf and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the Global Syn-Turf is Synthetic polyethylene turf, unspecified 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.
