Bbq Silicone Mat for Weber, Scratch Resistant Design with Organized Slots for Tools and Seasonings, Heat Resistant (black), Multicolor vs XL Floor Protection Mat: which is safer?

Where these two actually differ

• We flag Silicone additive/filler contamination (unspecified), Thermal degradation at extreme temperatures, Microplastic shedding if mat degrades and Coating degradation or peeling on the Weber and not on the Weber.
• We flag Polyethylene thermal degradation and VOC release and Microplastic shedding from mat degradation on the Weber and not on the Weber.
• The Weber is silicone (no nonstick fluoropolymer coating disclosed) where the Weber is Polyethylene (PE) or similar polymer protective mat, 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 Weber is the one to buy.
