SYNLawn Artificial Grass vs SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) from coating degradation under UV and heat, Microbial growth and odor in backing if drainage inadequate, Polyethylene fiber shedding and microplastic accumulation and Undisclosed water and stain-resistant coating chemistry, potentially PFAS on the Artificial Grass Liquidators and not on the AstroTurf.
• 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 Artificial Grass Liquidators.
• The Artificial Grass Liquidators is polyethylene with unspecified water/stain resistant coatings where the AstroTurf is Polypropylene (PP) astroturf, 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 Artificial Grass Liquidators grade, at 35% confidence against 72%, because it discloses less.
