Lekue Silicone Pastry Mat
Lower concern, silicone pastry mats are inherently PFAS-risk-minimal, though Lekue offers no explicit PFAS statement.
Lekue silicone pastry mats are made from food-grade silicone, a material not typically formulated with PFAS coatings or water-repellent coating treatments. The brand does not publicly disclose PFAS testing or make PFAS-free claims, but the material category itself carries lower risk than nonstick coatings like Teflon-type coating.

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
Lekue silicone pastry mats are made from food-grade silicone, a synthetic polymer with high heat stability and minimal leaching of harmful compounds under normal cooking conditions. Unlike non-stick coatings (Teflon-type coating/Teflon) or ceramic-glazed surfaces, silicone does not contain lead, cadmium, or substances that release toxic fumes when heated to typical baking temperatures. The material is inherently non-reactive and does not degrade into microplastics or micro-particles at standard kitchen use temperatures (up to ~220 degrees Celsius).
The brand's record and disclosure
Lekue is a Spanish kitchen product brand known for silicone-based bakeware and kitchenware. The company does not publicly disclose detailed chemical safety testing, third-party certifications, or PFAS statements on standard product pages or marketing materials. No major recalls, contamination reports, or safety controversies involving Lekue silicone mats have been documented in public records. The brand's silence on PFAS and chemical composition is typical of mid-range kitchen brands but falls short of transparency leaders.
How it compares in its category
Silicone baking mats present lower chemical risk than traditional coated metal sheet pans or ceramic-glazed bakeware, which may contain lead or release Teflon-type coating fumes at high heat. They are safer than single-use parchment paper treated with silicone coatings (which sometimes contain trace PFAS). Glass and stainless steel alternatives eliminate polymer concerns entirely but sacrifice non-stick convenience. Lekue's product sits in the middle-ground: safer chemistry than coatings, more practical than uncoated metal.
If you buy it
Avoid prolonged heating above 220 degrees Celsius (440 Fahrenheit); check your oven's max rack temperature. Hand wash with mild soap; do not use abrasive scrubbers or scouring pads that can puncture the surface and cause small pieces to shed. Replace if you notice visible tears, permanent discoloration, or surface cracking. Store flat in a cool, dry place away from sharp objects. These mats typically last 3-5 years with normal use.
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 leaching at high temperature
Food-grade silicone is stable below 220 degrees Celsius, but prolonged exposure to sustained high heat (broiling, direct flame) may cause minor leaching of oligomers or uncrosslinked siloxanes. Risk is low at standard baking temperatures and non-existent with proper use.
Surface degradation and micro-particle shedding
Repeated mechanical wear, abrasion with metal utensils, or exposure to sharp edges can cause microscopic tears or cracking in the silicone matrix over time. This may shed tiny particles into food, though clinical significance at trace levels remains unestablished.
Mold and bacterial growth if stored damp
Silicone mats are porous enough to trap moisture if washed and stored without complete drying. Standing water or humid storage can promote mold colonization in crevices, though visible mold would be obvious before creating a health risk.
Additive migration from colorants or flame retardants
Food-grade silicone formulations should not contain added flame retardants, heavy metal pigments, or phthalates, but Lekue provides no ingredient disclosure. No contamination recalls or test failures for this brand are documented in public sources.
Lead or cadmium in surface coatings (if any)
Lekue silicone mats do not carry ceramic, enamel, or glaze coatings, so traditional lead/cadmium contamination routes do not apply. The silicone substrate itself is not a typical vector for these heavy metals.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
