Weber Griddle Mid-Shelf Grill Mat
Skip until Weber discloses mat coating composition, silicone mats often contain PFAS as slip agents.
Weber doesn't disclose the coating chemistry on this griddle mat. Silicone-based mats often use PFAS for nonstick and release properties, and some formulations may contain them.

Material
silicone mat (coating composition unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Silicone coating degradation and volatiles
Unspecified topcoat or slip agent on silicone mats can degrade at high temperatures, potentially releasing volatile organic compounds or breakdown products. Risk increases if coating composition includes fluorinated additives (which Weber has not ruled out).
Leaching from coating into food
If the mat's slip or anti-stick coating migrates into fatty foods or oils at high heat, direct contact transfer is possible. No reported incidents for this specific product, but risk depends on coating identity and thermal stability.
Off-gassing of unreacted oligomers or residual solvents
Silicone mats may release low-level volatile compounds during initial use or at sustained high temperatures, particularly if manufacturing processes left unreacted siloxane oligomers or processing aids in the coating. Adequate ventilation during first use is prudent.
What’s reassuring
Thermal stability and structural integrity loss
Food-grade silicone itself is stable to 400-500 degrees Fahrenheit, and no recalls or widespread reports of mat failure at typical grill temperatures have been documented for Weber or similar brands. Risk depends on actual heating patterns and grill surface temperature.
Contamination from previous use or storage
Reusable mats can trap food residue or moisture in surface irregularities; improper cleaning or storage allows bacterial growth. This is a use-and-maintenance issue, not an intrinsic material hazard, but relevant to food safety.
The full breakdown
What it's made of and why it matters
This is a silicone-based grill mat, likely a food-grade silicone substrate with an unspecified topcoat or slip agent applied by Weber. The coating composition is the critical unknown: silicone mats commonly use fluorinated additives (PFAS compounds) as slip and anti-stick agents, and Weber has not publicly disclosed whether this mat contains them. Without that information, the safety profile of the mat itself cannot be fully assessed, though pure silicone is generally considered stable at typical grill temperatures (up to 400-500 degrees Fahrenheit).
The brand's record and disclosure
Weber is a major grill manufacturer with a strong consumer presence, but the company has remained silent on PFAS use in its silicone products and mat coatings. This silence is notable given that competing cookware and mat brands have begun publicly committing to PFAS-free formulations; Weber's lack of transparency here stands in contrast. No major recalls specific to this mat have been documented, but the absence of disclosure rather than absence of risk is the governing concern.
How it compares in its category
Silicone grill mats are broadly popular because they are reusable and withstand heat better than paper alternatives. However, many competitors in this category (including OXO, Cuisinart, and Amazon Basics silicone mats) have either disclosed PFAS-free formulations or provide clearer material documentation. Weber's refusal to specify coating chemistry puts this product at an information disadvantage relative to transparent brands; mats made from uncoated silicone fabric or metal mesh alternatives exist and carry lower coating uncertainty.
If you buy it
Do not exceed the manufacturer's stated temperature limit, as silicone degradation accelerates above 500 degrees Fahrenheit and may release volatile compounds. Keep the mat clean and dry between uses; prolonged moisture exposure under coating seams can accelerate degradation and potential leaching. Replace the mat if you observe discoloration, surface cracks, or a chemical odor during heating, all signs of coating breakdown. Contact Weber customer service to request material safety data and coating composition before purchase if possible; consumer demand for transparency may prompt disclosure.
