Scrapbook.com Non-Stick Silicone Craft Mat
Silicone mats pose lower PFAS concern than coated cookware.
Silicone is naturally PFAS-free and needs no fluorine coatings, though Scrapbook.com says nothing about testing.

Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
Mold or bacterial growth from moisture retention
Silicone mats can trap moisture in creases or seams if stored wet or in humid conditions, potentially supporting mold growth. This is a hygiene issue rather than chemical toxicity; proper drying and storage mitigate the risk.
What’s reassuring
Silicone degradation and particle shedding
No established reports of food-grade silicone mats shedding toxic particles under normal craft or food-contact use. Silicone is chemically stable and does not off-gas harmful volatile organic compounds.
Heavy metals
Silicone products rarely contain heavy metals; this mat appears to be unfilled or minimally filled silicone. No recalls or testing reports suggest lead, cadmium, or antimony in Mastrad silicone mats.
Source: FDA ↗Thermal stability at high temperatures
Food-grade silicone is typically rated safe to 200-220°C (400-450°F). This craft mat is not intended for oven use, so thermal degradation is not a practical concern in normal applications.
Allergen or irritant potential from additives
No formaldehyde releasers, azo dyes, or known allergens are typical in food-grade silicone products. Mastrad has not reported additive-related adverse events for this mat.
The full breakdown
What it's made of and why it matters
This product is a silicone-based craft mat, not cookware in the traditional sense, though it shares the silicone material class. Food-grade silicone is a synthetic rubber polymer that does not leach problematic chemicals under normal temperatures or with water exposure. Unlike coated non-stick cookware (Teflon-type coating/Teflon), silicone mats have no fume risk and do not degrade into airborne particles when heated moderately.
The brand's record and disclosure
Mastrad is a French kitchenware and craft supplies manufacturer with no major public safety recalls or controversies on record for this product line. The brand does not proactively disclose PFAS testing or certifications, which is typical for silicone product makers but leaves questions unanswered. No third-party certifications (FDA, NSF) have been identified for this specific mat.
How it compares in its category
Silicone craft mats are among the lowest-risk non-stick surfaces available, safer than traditional Teflon-type coating cookware in terms of fume risk and thermal degradation. Unlike plastic cutting boards, silicone does not shed microplastics into food or liquids. The main trade-off is durability and staining over time, but this does not pose a chemical safety concern.
If you buy it
Hand-wash or use warm (not boiling) water to preserve the mat's surface integrity. Do not use abrasive scrubbers that can degrade silicone; mild soap and a soft cloth are sufficient. Replace if surface becomes visibly torn, cracked, or heavily stained with mold or discoloration. Store flat or rolled loosely to avoid permanent creasing.
