NoStik Silicone Roll and Pastry Mat
Skip this. Teflon brand product contains PFAS compound Teflon-type coating.
This mat features a Teflon Teflon-type coating nonstick coating, which is a PFAS-containing Teflon-family coating. If you're worried about forever chemicals, uncoated silicone or parchment works better.

Material
Teflon-type coating (Teflon) nonstick Teflon-family coating on silicone base
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
PTFE / Teflon confirmed
Contains Teflon-type coating, also called Teflon, a type of PFAS.
Category baseline
PFAS exposure happens more often with clothing products.
Teflon-type coating degradation and microparticle release
Mechanical wear, heat cycling, or physical damage to the Teflon-type coating layer can generate microparticles. No specific data exists for this product, but nonstick coatings are known to degrade under repeated bending or scraping.
Thermal decomposition of Teflon-type coating
Teflon-type coating begins to break down above 500°F (260°C), releasing potentially toxic fumes including perfluorooctane. Home baking typically stays below this, but oven broilers or high-heat applications pose a risk.
Silicone base leaching
While food-grade silicone is generally stable, some unlabeled silicone products may leach oligomers (small silicone molecules) at elevated temperatures. Teflon brand does not disclose silicone grade or migration testing for this mat.
Coating adhesion failure over time
Nonstick coatings can separate from silicone substrates, especially under thermal cycling or flexing. This product has no published durability warranty or replacement guarantee on file.
What’s reassuring
Aluminum leaching
No aluminum is documented in the construction of this silicone-Teflon-type coating mat, so leaching risk from this source is not applicable.
The full breakdown
What it's made of and why it matters
This mat combines a silicone elastomer base with a Teflon-type coating (polytetrafluoroethylene, brand-name Teflon) nonstick coating. Teflon-type coating itself is a stable Teflon-family coating when intact, but the coating can degrade under heat stress, physical wear, or damage, potentially releasing microparticles. The silicone substrate is generally inert, but the Teflon-type coating layer is the primary safety concern in this product class.
The brand's record and disclosure
Teflon (DuPont/Chemours) has a documented history of PFAS manufacturing and environmental contamination. The company has faced litigation over PFOA (a PFAS precursor) in drinking water supplies near manufacturing plants. The brand has not disclosed specific PFAS residue levels or migration data for consumer products like this mat. No current third-party certifications (e.g., GOTS, OEKO-TEX, or PFAS-free badges) are listed for this product line.
How it compares in its category
Silicone-based pastry mats are inherently safer than traditional nonstick cookware because silicone itself does not contain Teflon-type coating. However, this specific product pairs silicone with a Teflon-type coating, combining two different chemistries. Non-coated silicone mats or uncoated parchment paper alternatives avoid Teflon-type coating entirely and carry substantially lower PFAS exposure risk.
If you buy it
Keep the mat below 350°F (175°C) to minimize coating stress and degradation. Inspect regularly for cracks, peeling, or discoloration. Replace immediately if the coating shows visible damage. Hand wash only; avoid abrasive scrubbers and dishwasher heat. Do not use under direct flames or in broiler settings. If durability cannot be maintained, transition to a non-Teflon-type coating alternative.
