Wilton Silicone Baking Mat Non-Stick Heat Resistant Mint Green 10.25 x 16
Skip unless Wilton discloses silicone coating chemistry.
Wilton does not disclose whether this silicone non-stick mat contains PFAS. Some silicone coatings use PFAS additives; independent testing is unavailable.

Material
Silicone non-stick 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.
Non-stick coating degradation and shedding
Silicone mats can develop small cracks or peeling over time, especially if washed in dishwashers or exposed to sharp utensils. If the non-stick surface degrades, particles may be ingested; this risk is low but increases with age and abuse.
Heat-induced leaching from non-stick layer
If the unspecified non-stick coating contains PFAS or other synthetic polymers, elevated temperatures (above 400F) may increase migration into food. Wilton's silence on composition makes this risk unquantifiable but plausible.
Bacterial growth in worn or textured surfaces
Over time, silicone mats may develop microscopic wear patterns or adhesion loss that trap bacteria or food residue. Proper hand washing and timely replacement minimize this risk.
What’s reassuring
Silicone base leaching
Pure silicone polymers are considered inert at normal baking temperatures and FDA-cleared for food contact. No established evidence of harmful leaching from silicone itself at typical baking temperatures (under 450F).
Heavy metals
The mint green color requires pigmentation; however, no recalls or public testing of Wilton silicone mats for lead or cadmium have been reported. Standard food-contact color regulations apply, but undisclosed pigment sources remain a minor information gap.

What it's made of and why it matters
This product is a silicone non-stick baking mat, which means a silicone polymer base with an unspecified non-stick coating. Wilton has not publicly disclosed the complete chemical composition of their silicone formulation or whether their non-stick surface uses Teflon-type coating (Teflon-type) or alternative chemistries. Silicone itself is generally considered inert at normal baking temperatures, but the non-stick coating composition determines whether PFAS or other concerning substances migrate into food.
The brand's record and disclosure
Wilton, owned by Groupe SEB (which makes T-Fal and other cookware brands), does not publicly disclose PFAS content or chemistry transparency for this product line. No recalls specific to this mat have been recorded, and no third-party testing of Wilton silicone baking mats for PFAS or heavy metals is publicly available. The brand's silence on coating chemistry is a red flag in an industry where major competitors (Oxo, Calphalon) have begun disclosing non-PFAS formulations.
How it compares in its category
Silicone baking mats occupy a middle ground between single-use parchment paper and traditional non-stick bakeware. Unlike hard non-stick cookware (pans, baking sheets), silicone mats are less prone to coating degradation and flaking, reducing ingestion risk. However, they lack the transparency of PFAS-free competitors like Silpat (which discloses no PFAS) or parchment alternatives, and they are more durable than parchment, so long-term chemical exposure becomes a consideration if the coating contains PFAS.
If you buy it
Use at or below 400F (manufacturer typically recommends this for silicone); higher temperatures increase leaching risk and may degrade the non-stick surface. Hand wash only; dishwasher heat and detergents may compromise the coating. Replace immediately if the surface develops tears, cracks, or visible wear, as damaged non-stick surfaces can shed particles. If you have ongoing concerns about PFAS, contact Wilton directly requesting their coating chemistry disclosure; lack of response should prompt switching to a brand with published non-PFAS certification.
