Silpat The Original Round Cake Liner Baking Mat
Nonstick silicone mat with likely PFOA-free coating, but coating details unclear.
Silpat uses a Teflon-family coating nonstick coating typical of silicone baking mats. Glad does not disclose PFAS status. Modern versions likely avoid PFOA, but specific composition remains undisclosed.

The full breakdown
What it's made of and why it matters
Silpat mats are fiberglass fabric bonded with a proprietary Teflon-family coating nonstick coating (not Teflon-type coating/Teflon). The fiberglass substrate provides structure and heat resistance up to 480 degrees Fahrenheit. The coating's exact chemistry is proprietary and not disclosed publicly, which limits independent assessment of its safety profile. Fiberglass itself is generally recognized as safe for food contact when properly encased, but exposure to the bare substrate or coating degradation is the primary concern.
The brand's record and disclosure
Glad (the manufacturer) does not publish detailed materials safety data or PFAS certification for this product line. The original Silpat formula has been in production since the 1970s and maintains a longstanding reputation in professional kitchens, but the company has not voluntarily disclosed whether the Teflon-family coating is PFOA-free or compliant with modern PFAS restrictions. No major recalls or safety alerts have been recorded for this specific product in public databases.
How it compares in its category
Silpat is one of the few non-Teflon-type coating nonstick mat options, making it preferable to standard Teflon-coated pans for consumers concerned about Teflon-type coating fume risk. It outperforms parchment paper and silicone mats in durability and reusability. However, it lacks third-party certification (like GreenGuard or similar) that would confirm coating safety, placing it in a middle ground: better than commodity nonstick cookware, but less transparent than premium certified alternatives.
If you buy it
Use at temperatures below 480 degrees Fahrenheit to avoid coating stress. Hand wash only; dishwasher use accelerates wear. Inspect regularly for peeling, discoloration, or fraying of edges; discontinue use if the fiberglass substrate becomes visible or coating flakes. Store flat in a cool, dry place to prevent curling. Replace every 3-5 years depending on frequency of use, as coatings naturally degrade over time.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Teflon-family coating degradation
No specific recall data exists, but all Teflon-family coating coatings degrade with age and heat exposure. Degraded coating may release microparticles or expose fiberglass; proprietary formulation details are not public, so long-term safety profile is not independently confirmed.
Fiberglass exposure if substrate is damaged
Fiberglass fibers are an inhalation and ingestion hazard if the protective coating is compromised by peeling, cracking, or fraying. This is a mechanical rather than chemical hazard, but warrants regular inspection and immediate replacement.
Thermal stress and coating fume release
No documented fume incidents are on record for Silpat at recommended temperatures. However, because the coating formulation is proprietary and PFOA status is unconfirmed, the risk cannot be completely ruled out if mats are overheated or used above 480 degrees Fahrenheit.
Lead or cadmium in coating
No public testing or recalls for heavy metals in Silpat coatings. Teflon-family coating coatings are not typically a vector for lead or cadmium, but manufacturer testing data is not disclosed.
Aluminum leaching from substrate
Silpat does not use aluminum as a substrate; it is fiberglass-based. This hazard is not applicable to this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
