SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs Sport Artificial Turf - NEW!: 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 Sportmaster.
• We flag Flame retardants in backing or infill, Heavy metals in rubber crumb infill, Microplastic shedding from fiber degradation and Leaching of colorants and UV stabilizers on the Sportmaster and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the Sportmaster is Synthetic turf fibers, likely polyethylene or polypropylene with unknown infill and coatings, which is most of the difference in these two grades.
• The gap is 55 points, wide enough that this is not a close call, and the AstroTurf is the one to buy.
• We are less certain about the Sportmaster grade, at 35% confidence against 72%, because it discloses less.
