OXO Pastry Mat
Silicone pastry mat; coating chemistry unclear without brand disclosure.
OXO's silicone pastry mats are typically lower-risk, but the company keeps coating details secret and won't say whether PFAS are involved. Transparency is missing.

Material
Silicone mat, coating unspecified
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.
Coating degradation and leaching from unspecified surface treatment
OXO has not disclosed whether the pastry mat surface includes Teflon-type coating, siloxane resins, or other additives beyond base silicone. Heat, friction, and age can degrade unknown coatings and potentially release particles or chemicals into food.
Silicone leaching under extreme heat or mechanical stress
While food-grade silicone is generally stable, degradation at high temperatures (above 220 C) or from repeated scratching can release oligomeric siloxanes. This is a known risk for all silicone mats, and OXO provides no upper-temperature guarantee.
Microplastic or polymer particle shedding from surface wear
Silicone and coated mats shed microscopic particles with age and use, particularly if the mat is folded, cracked, or scratched. No specific recall exists for OXO pastry mats, but this is a material-class concern.
What’s reassuring
Lead
No recalls or testing results on record for OXO pastry mats. Silicone is less prone to heavy-metal contamination than ceramic or enamel, but unpublished dye chemistry cannot be fully ruled out.

Off-gassing risk is minimal with silicone mats compared to textiles or plywood furniture, but bonding agents between layers or at seams are not disclosed by OXO.

What it's made of and why it matters
OXO silicone pastry mats are primarily food-grade silicone, a synthetic rubber polymer that resists heat and sticking without non-stick coatings. The hazard lies in any unknown surface coating or gloss applied for slip resistance or durability; without OXO's full disclosure, you cannot rule out Teflon-family coating additives (Teflon-type coating, PFOA precursors) or other chemical finishes. Silicone itself is stable at typical baking temperatures (up to ~220 C), but degradation or leaching depends on the complete formulation.
The brand's record and disclosure
OXO Good Grips has a reputation for consumer-friendly design but has not published detailed material safety data sheets or coating specifications for its pastry mat line. The brand has faced no major recalls for this product category, but their silence on PFAS and non-silicone additives is a red flag in a category where Teflon-family coating coatings are common. OXO does not advertise PFAS-free status or third-party certification (e.g., GOTS, NSF) for kitchen textiles or mats.
How it compares in its category
Silicone pastry mats are a safer alternative to Teflon-type coating-coated fiberglass or plastic mats in general; they avoid the fume risk of Teflon degradation. However, uncoated parchment paper or glass baking surfaces are lower-chemical options if you prioritize minimal processing. OXO's mat sits in the mid-market; premium brands (e.g., OXO's own certified lines, or Silpat, which disclose materials) often provide full ingredient transparency, while budget alternatives may use less-stable silicone compounds.
If you buy it
Keep use below 220 C (428 F); most baking falls well within this range, but avoid direct broiler or very high-temperature cooking. Hand wash with mild soap; dishwasher use may degrade the surface coating over time. Replace the mat if you notice discoloration, stickiness loss, or surface cracking, as these suggest polymer breakdown. Store flat in a cool, dry place; do not fold or crease repeatedly, which can stress the coating and release particles.
