Mastrad Silicone Macaron Baking Sheet Set of 2
Lower concern. Silicone itself does not require PFAS.
Mastrad's silicone macaron baking mats are made from food-grade silicone, an inherently PFAS-free material. No coating or treatment typically introduces PFAS in this product category.

The full breakdown
What it's made of and why it matters
These sheets are made from food-grade silicone, a polymer backbone of silicon and oxygen with organic side chains. Food-grade silicone used in baking mats does not contain BPA, phthalates, or PVC plasticizers by design. Silicone's chemical stability at moderate baking temperatures (typically safe to 230°C/450°F) means it does not leach volatile compounds like some plastics do when heated. The non-stick surface is inherent to silicone's molecular structure, not a coating that can degrade.
The brand's record and disclosure
Mastrad is a French kitchenware brand with no major product recalls or chemical safety controversies on record in public databases. The company does not publish detailed material sourcing or third-party test certifications on its website; transparency is minimal but absence of scandal is notable. Food-grade claims are standard in the category but not independently verified by the brand in published statements. No known litigation or regulatory action against Mastrad products in this category.
How it compares in its category
Silicone baking mats are a safer alternative to traditional Teflon-coated (Teflon-type coating) cookware, which can off-gas fumes if overheated. They outperform parchment paper (which can break down at high heat and is often treated with silicone or PFAS coatings) in reusability and durability. Most competitors (Silpat, OXO, Wilton, Matfer) use similar food-grade silicone with comparable safety profiles and no distinguishing hazard advantage or disadvantage. Price and non-stick performance differ, but chemical safety is roughly equivalent across major brands in this segment.
If you buy it
Wash before first use and dry completely to remove any manufacturing residue. Do not exceed 230°C (450°F) regularly, as high temperatures can cause microscopic silicone particle shedding over years of use, though this is not classified as a health hazard by regulatory bodies. Replace if the surface becomes visibly torn, sticky, or discolored, as structural failure increases contamination risk. Store flat or loosely rolled to prevent creasing that can trap moisture and food debris.
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 particle migration from surface wear
Repeated use above 230°C and mechanical abrasion can cause microscopic silicone particles to shed into food. This is not classified as toxic by food authorities (silicone is inert), but cumulative ingestion is not extensively studied in humans over decades.
Leaching from additives or processing aids
Food-grade silicone formulations used by major manufacturers are designed to minimize leachable compounds. No published studies document harmful chemical leaching from Mastrad or comparable silicone baking mats under normal use conditions.
Coating degradation or defect contamination
Unlike Teflon-type coating or ceramic coatings, silicone is the material itself, not a coating layer, so coating peeling or flaking is not a failure mode. Manufacturing defects (impurities trapped in silicone) are possible but not documented for this brand.
Bacterial or mold growth in pores
Silicone mat surface has microscopic pores that can harbor bacteria or mold if not dried thoroughly after washing. This is a hygiene issue rather than a chemical hazard; proper cleaning and air-drying mitigate the risk.
Off-gassing of volatile organic compounds (VOCs)
Food-grade silicone does not release odorous or toxic VOCs at normal baking temperatures, unlike some non-stick coatings. Slight odor when new is common and dissipates after a few washes; no health concern is documented.
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.
