Is Black & White Silicone Work Mat non-toxic? What it is made of

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.

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. The brand 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.

70/ 100

What’s reassuring

✅

Base material not linked to PFAS

The main material recorded for this product is not one associated with PFAS.

100/ 100
✅

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 silicone products.

95/ 100
✅

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 mats under normal use, and silicone does not produce the acrid fume signature of Teflon-type coating (Teflon) degradation.

95/ 100
✅

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.

How is this PFAS grade calculated?

The brand's record and disclosure

The brand 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 have lower concern than nonstick cookware for coating degradation and leaching, lower concern than some ceramic glazes for heavy metals, and lower concern than plastics for heat sensitivity. 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.
