Bradshaw International Sweet Creations High-Temp Silicone Oven Baking Mat
Silicone mat likely poses lower PFAS concern, but coating is unclear.
This silicone baking mat carries lower PFAS risk than Teflon-type coating nonstick products, but coating details remain hidden.

What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PFAS
Silicone mats often require mold-release agents or topcoat additives during manufacture. Good Cook does not disclose whether this product uses fluorinated compounds; industry-wide prevalence of PFAS in non-stick coatings makes this plausible but not confirmed for this specific mat.
Source: ATSDR ↗Fiberglass mesh exposure if torn
Many silicone mats are reinforced with fiberglass to prevent sagging. If the silicone coating tears or delaminates, fiberglass fibers may shed into food. This risk is low under normal use but increases with age, dishwasher cycling, or physical damage; immediate replacement is warranted if coating integrity is compromised.
Bacterial or mold growth if poorly dried
Silicone's porous microscopic structure can harbor bacteria or mold if mats are stored wet or in humid conditions. This is a maintenance issue, not an inherent material hazard; thorough air-drying before storage mitigates risk.
What’s reassuring
Silicone leaching at high temperature
Food-grade silicone is chemically stable well above typical oven temperatures (500-600°F). No peer-reviewed or regulatory reports document leaching of silicone oligomers or monomers into food at normal cooking use; degradation typically requires sustained exposure above rated limits.
Off-gassing or fume inhalation
Unlike Teflon-type coating (Teflon) cookware, silicone does not emit fluorinated gases when heated. No established reports of volatile organic compound (VOC) release or inhalation hazards from silicone baking mats at standard oven temperatures.
The full breakdown
What it's made of and why it matters
This product is a silicone-based baking mat, typically food-grade silicone reinforced with fiberglass mesh. Silicone itself is a synthetic polymer considered chemically inert at typical kitchen temperatures and does not leach the plasticizers (phthalates) or endocrine disruptors common in PVC or polycarbonate. The "high-temp" designation suggests it tolerates oven heat up to 500-600°F, though the manufacturer's exact upper limit is the controlling spec. No public testing has identified lead, cadmium, or other heavy metals in this product line.
The brand's record and disclosure
Good Cook (Bradshaw International) is a mid-market kitchenware brand with no significant safety recalls or public disclosure controversies on record for silicone mats. The brand does not prominently advertise third-party certifications (e.g., FDA, NSF) for this specific item, nor does it publish ingredient or coating transparency statements. This silence on coating composition is the main transparency gap; many silicone mats use undisclosed release agents or topcoats that could theoretically contain PFAS or other processing aids.
How it compares in its category
Silicone baking mats are generally considered a safer alternative to parchment paper (which may contain PFAS) and Teflon/Teflon-type coating-coated pans (which carry fume-inhalation risk if overheated). This product sits in the mainstream commercial tier; it is not premium (no brand certifications) but also not a discounted off-brand known for corner-cutting. Direct competitors include Silpat, OXO, and store-brand silicone mats, most of which are functionally equivalent in hazard profile.
If you buy it
Confirm your oven's max temperature and stay below the mat's rated ceiling (typically 500-600°F) to avoid degradation or off-gassing. Hand wash after each use with mild soap and warm water; dishwasher cycling can accelerate silicone wear over time. Replace the mat if you notice stickiness increasing, discoloration, or visible cracking, as these signs indicate breakdown of the silicone matrix. Store flat in a cool, dry place to prevent permanent creasing or warping.
