What’s concerning

♾️

Category baseline

PFAS exposure happens more often with clothing products.

70/ 100
♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
💨

Volatile organic compounds (VOCs) / off-gassing

New silicone products may release odorous VOCs, especially when first heated or in warm conditions. This is typically mild for craft mats and not associated with established health harm at consumer exposure levels, but sensitive individuals may notice odor.

70/ 100
💨

Thermal stability and fume risk above rated temperature

If accidentally exposed to temperatures exceeding 450-500 degrees Fahrenheit, silicone can degrade and release toxic fumes. Craft use is unlikely to trigger this, but misuse (e.g., placement near stovetops or in ovens) could be a risk.

70/ 100
⚠️

Bacterial or mold growth if moisture-trapped

If the mat remains damp or is stored in a humid environment, mold or mildew may grow on the surface. This is a maintenance issue, not an inherent material hazard; proper drying and storage mitigate this.

70/ 100

What’s reassuring

Safe base material

Made from ceramic, mineral, or natural fiber with no PFAS risk.

100/ 100

Surface degradation and material shedding

No reports of silicone mats breaking down into microparticles or flaking coatings. Scratching or cutting the surface does not create a leaching hazard, as there is no coating layer to separate.

Lead

Silicone rubber formulations do not inherently contain or require these metals for function. No recalls or test data suggest contamination in this product category.

The full breakdown

What it's made of and why it matters

This product is silicone rubber, a synthetic polymer that does not contain the ceramic glazes, metal coatings, or Teflon-type coating (Teflon) found in traditional cookware. Silicone is chemically inert at typical craft and light-cooking temperatures, meaning it does not leach significant compounds into food or materials placed on it. The absence of coating layers means no degradation pathway like chipped enamel or worn non-stick surfaces. However, silicone can off-gas volatile organic compounds (VOCs) when new or heated above its safe operating range, though this is typically minimal for craft use.

The brand's record and disclosure

Stampin' Up! is a privately held craft supply company with no public safety certifications or hazard disclosures on record for this product line. The brand does not publish material safety data sheets or PFAS testing results for silicone mats. No recalls or safety complaints specific to this product have been documented in public databases. The lack of transparency is typical for craft-supply brands, which are not required to disclose chemical composition for non-food items.

How it compares in its category

Silicone craft mats are considerably safer than traditional cookware in terms of coating hazards, as they eliminate lead, cadmium, and Teflon-type coating risks entirely. Compared to fabric work surfaces or plastic cutting mats, silicone is more durable and does not shed microplastics when cut or abraded. Most competing silicone mat brands (both craft and kitchen-grade) share the same base material profile and carry similar minimal hazard profiles, making this product representative of the category rather than distinctive.

If you buy it

Store the mat away from direct heat and sunlight to minimize VOC off-gassing and color degradation over time. Do not use it above 400-450 degrees Fahrenheit if heat-exposure occurs (though craft use typically avoids this). Wash with warm soapy water; avoid harsh abrasives that could degrade the surface, though minor scratching does not create a leaching risk. Replace the mat if it becomes sticky, discolored, or shows visible breakdown, though silicone mats typically have a 5-10 year lifespan with normal care.
