Blue Moon Beads XL Silicone Mat
Lower PFAS concern; silicone mat is inherently safe material.
Silicone mats are non-coated, inherently PFAS-free materials with no chemical treatments needed for function. No PFAS risk expected from the material itself.

The full breakdown
What it's made of and why it matters
This product is a silicone baking mat, a non-coated elastomer material composed of silicone polymer chains. Silicone is chemically inert across typical cooking temperatures (up to 600F for most mats) and does not leach harmful substances into food the way coated cookware can. Unlike non-stick coatings such as Teflon-type coating (Teflon), silicone has no degradation mechanism that releases fumes, and it contains no ceramic, enamel, or glaze layers that could harbor lead or cadmium.
The brand's record and disclosure
Pyrex is owned by Instant Brands and has a long-standing reputation for rigorous cookware safety standards, particularly in glass bakeware. The company does not publicly disclose silicone mat PFAS content (hence the 'silent' stance noted), which is common in the industry; however, Pyrex's overall brand record shows no established recalls or safety violations for silicone products. Pyrex cookware products are generally compliant with FDA food-contact material regulations.
How it compares in its category
Silicone baking mats are considered among the safest non-coated baking surfaces, preferred over non-stick pans that can degrade or release fumes. Compared to parchment paper (which can off-gas at very high heat) and reusable Teflon-coated alternatives (which carry Teflon-type coating fume risk), silicone mats offer durability without chemical leaching risk. Pyrex-branded silicone mats are mid-range in price and widely regarded as reliable within the silicone mat category.
If you buy it
Hand wash the mat with mild soap and warm water; do not use abrasive scrubbers that could degrade the silicone surface. Do not exceed 600F (check product label for exact limit) to avoid material softening. Replace the mat if visible tears, discoloration, or sticky residue develop, as these indicate polymer degradation. Store flat or rolled loosely in a cool, dry place away from direct sunlight to extend lifespan.
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
No established evidence that high-quality food-grade silicone leaches harmful substances into food at normal baking temperatures. Pyrex product line uses FDA-compliant silicone formulations.
Teflon-type coating/fume risk
Silicone mats contain no Teflon-family coating, so no risk of Teflon-type coating degradation fumes at high heat. This is a fundamental advantage over non-stick alternatives.
Coating degradation over time
Silicone itself does not have a discrete coating layer, but the material can degrade with age, abrasion, or heat cycling. Physical damage (tears) exposes underlying silicone; discoloration or stickiness suggests polymer breakdown and warrants replacement.
Lead or cadmium in surface
Silicone mats have no ceramic, enamel, or glaze layer where lead or cadmium contamination typically occurs in cookware. Not a relevant hazard for this product type.
Odor or off-gassing during initial use
Some silicone products emit a faint chemical odor when new, attributed to residual manufacturing compounds. This typically dissipates with hand washing and airing; it is not an established toxicological concern but may indicate incomplete curing of the silicone.
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.
