Green Valley Pro 105 vs SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf: which is safer?

Where these two actually differ

• We flag Backing material leachables (unknown composition), Heavy metals in colorants, VOC off-gassing from UV stabilizers and processing aids and Microfiber shedding and soil contamination 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 (PE) synthetic fibers, backing unknown where the AstroTurf is Polypropylene (PP) astroturf, which is most of the difference in these two grades.
• We are less certain about the Artificial Grass Liquidators grade, at 45% confidence against 72%, because it discloses less.
