Lekue Macaron Mat
Lower-concern baking mat; silicone-based with no known PFAS risks, but brand offers no explicit statement.
Lekue Macaron Mats are silicone-based non-stick baking mats. Silicone is not a Teflon-family coating and is not known to contain PFAS in standard formulations. The brand provides no public PFAS statement, but the material itself carries lower concern than Teflon-family coating or Teflon-type coating coatings.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Lekue Macaron Mat is food-grade silicone, a thermoset polymer that does not degrade into small particles or leach chemicals under normal baking temperatures. Silicone mats are chemically inert and remain stable even when heated repeatedly to typical oven temperatures (up to 220°C/428°F for most Lekue products). Unlike non-stick coatings on metal bakeware, silicone does not rely on Teflon-type coating or other volatile Teflon-family coating, eliminating fume risk at normal use. The material's lack of reactive surface means no known leaching of heavy metals, BPA, or phthalates.
The brand's record and disclosure
Lekue is a Spanish cookware manufacturer with a public commitment to food-safe silicone products and CE marking (European safety compliance). The brand does not publish explicit PFAS statements, but silicone-based products from this manufacturer are not known to contain PFAS by design. Lekue products are regularly imported and sold in North America without documented safety recalls related to chemical leaching. The company provides basic care instructions and temperature limits, indicating attention to product safety communication.
How it compares in its category
Silicone mats are among the safest non-stick baking surfaces available, avoiding both Teflon-type coating fume concerns and ceramic/enamel coating degradation risks present in traditional metal sheet pans. They outperform reusable parchment in durability and require no disposable waste. Compared to non-stick metal cookware, silicone mats eliminate the risk of coating flaking or leaching from mechanical wear. The Lekue version is priced at the mid-to-premium tier for silicone mats, reflecting quality European manufacturing.
If you buy it
Observe the maximum temperature rating (typically 220°C) to avoid silicone degradation or brittleness over time. Wash by hand in warm soapy water or dishwasher on low heat; aggressive scouring is unnecessary and can wear the surface. Store flat or loosely rolled to prevent permanent creasing. Replace the mat if it becomes sticky, discolored, or develops an odor, which may indicate silicone breakdown; well-maintained mats typically last 5+ years.
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.”
Silicone degradation and leaching (high temperature)
At temperatures well above recommended use (>250°C), silicone can begin to break down and potentially release oligomers or degradation byproducts. Normal oven baking at 180, 220°C poses negligible risk; risk rises with prolonged broiling or direct flame contact.
Microplastic shedding
Silicone mats do not shed microplastics under normal use conditions, as the material is a thermoset polymer that does not fragment like thermoplastics. No established reports of particle release from Lekue silicone mats in published literature or recall data.
Lead or cadmium in colorants
Lekue silicone mats are not glazed or enameled; color is incorporated into the silicone bulk material. No documented cases of heavy metal contamination in Lekue silicone cookware, and European manufacturing standards restrict such additives.
Bacterial or fungal growth if stored wet
If mats are stored damp or in humid conditions without drying, silicone's porous microstructure can support mold or mildew growth, particularly in the creases. Proper air-drying before storage prevents this; no product-specific incidents reported.
Odor or taste transfer (not toxicity)
Silicone mats can absorb strong food odors or flavors, particularly from spiced baked goods, but this is organoleptic rather than a safety hazard. Odor persistence does not indicate chemical leaching or degradation.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
