What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Silicone leaching (oligomers)
Uncrosslinked siloxane oligomers can migrate into fatty foods at elevated temperatures; risk is low for room-temperature use and brief heating, but not zero at temperatures above 400F sustained over time. Good Cook has not published migration data for this specific mat.
Mold and bacterial growth if wet-stored
Silicone's porous microstructure can harbor moisture if not dried thoroughly after washing; this poses a hygiene risk (mold smell, visible discoloration) rather than a chemical hazard, but should trigger replacement if growth appears.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Pigment stability and migration
Carbon black and iron oxides used in silicone mats are chemically stable and do not migrate into food under normal conditions; no recalls or adverse reports are on record for Good Cook silicone products.
Heat-induced degradation or off-gassing
Food-grade silicone is engineered to resist breakdown up to its rated temperature limit; no odor or fume events are documented for Good Cook mats under normal use, and silicone does not produce the acrid fume signature of Teflon-type coating (Teflon) degradation.
Contaminant absorption from previous use
Silicone's inert nature means it does not readily absorb odors or stains from prior contact; new mats carry minimal risk of carryover contamination from manufacturing or storage.
The full breakdown
What it's made of and why it matters
This product is a food-grade silicone mat, a thermosetting polymer engineered to resist heat and not leach chemicals into food at normal cooking temperatures. Silicone mats are chemically inert compared to plastics or coated metals; they do not contain BPA, phthalates, or the reactive components found in epoxy or ceramic glazes. The black and white pigmentation uses standard colorants (likely iron oxides and carbon black), which are stable in silicone and do not migrate under typical kitchen use.
The brand's record and disclosure
Good Cook is a cookware and kitchen-tools brand owned by Groupe SEB; they have no public record of recalls or safety citations specific to silicone products. The company does not publish detailed chemical or PFAS disclosure statements for this product line. No established certifications (e.g., FDA food-contact approval documentation) are publicly documented for this specific mat, though silicone mats as a category are generally recognized as food-safe.
How it compares in its category
Silicone work mats are among the safest reusable food-contact surfaces because they avoid the coating-degradation and leaching risks of nonstick cookware, the heavy-metal concerns of some ceramic glazes, and the heat sensitivity of plastics. Glass or stainless-steel alternatives are similarly low-risk but less flexible. Budget silicone mats from lesser-known brands carry identical chemical profiles; brand distinction here is minimal.
If you buy it
Use at temperatures up to the manufacturer's stated limit (typically 400-500F for food-grade silicone); do not rest it directly on open flame or in a conventional oven above 450F for extended periods. Wash by hand or in the dishwasher; silicone does not degrade easily, so replacement is needed only if surface tears or becomes sticky (a sign of mold growth, not chemical breakdown). Avoid prolonged storage in direct sunlight, which may eventually discolor pigments but does not compromise food safety.
