Mastrad Silicone Macaron Baking Sheet
Lower concern. Silicone is inherently PFAS-free by design.
Mastrad's silicone baking sheet is made from silicone, a material not known to contain PFAS. No PFAS disclosures found from brand, but silicone's chemistry presents lower risk than Teflon-family coating nonstick coatings.

The full breakdown
What it's made of and why it matters
Mastrad's macaron sheet is food-grade silicone, a synthetic rubber polymer made from silicon and oxygen. This material is chemically inert at typical baking temperatures (up to 220°C / 428°F), meaning it does not leach chemicals into food or off-gas harmful fumes like Teflon-type coating cookware can. Silicone is inherently free of PFAS compounds because it contains no fluorine atoms and is not manufactured using fluorinated precursors.
The brand's record and disclosure
Mastrad is a French kitchenware company with no known product recalls or safety controversies on record. The company does not publicly disclose detailed material certifications or third-party testing results on their website, but this is typical for small specialty cookware makers. Food-grade silicone products from reputable manufacturers are generally compliant with FDA and EU food contact regulations by default.
How it compares in its category
Silicone baking mats are among the safest reusable baking surfaces. Unlike ceramic-coated metal sheets (risk of lead in glaze), non-stick coated pans (Teflon-type coating fume risk if overheated), or parchment paper (single-use waste), silicone mats pose no identified chemical leaching hazards at normal baking temperatures. They are durable, washable, and do not degrade into microparticles under standard use.
If you buy it
Hand wash or use low heat in the dishwasher to extend mat life and prevent brittleness. Do not expose to direct flame or use above 220°C (product spec limits). Replace if surface becomes visibly tacky, sticky, or discolored after many years of use, though silicone mats typically last 5-10 years. Store flat or loosely rolled to avoid permanent creases.
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 particle shedding
Over extended use (years), silicone can become tacky or shed microscopic particles if the polymer chain degrades. This is not a food safety issue at normal baking temperatures, but worn mats should be replaced as a precaution.
Heat stability and off-gassing
Food-grade silicone is stable up to 220°C. No credible reports of chemical off-gassing from Mastrad silicone sheets at recommended temperatures. Risk only arises if mat is exposed to direct flame or extreme heat.
Contaminants in polymer resin
No recalls or test findings document heavy metals, BPA, or phthalates in Mastrad silicone baking sheets. Food-grade silicone by regulatory definition is screened for such contaminants.
Adhesive or ink on printed surfaces
If the macaron sheet has printed markings or grids, these are typically food-safe inks. No specific issue is documented for Mastrad products, but inspect for any peeling ink before extended use.
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.
