What Crate & Barrel Silicone Pastry Prep Mat is made of, ingredients and materials
This mat is food-grade silicone, a synthetic rubber polymer that is thermoset (cross-linked) and does not leach plasticizers or BPA because it contains neither. Silicone is inherently non-reactive with acidic, oily, or hot foods up to typical baking temperatures (around 500F). Unlike plastic liners or coated papers, silicone does not degrade into microplastics or release volatile compounds during normal use.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Silicone degradation and surface leaching
Silicone can degrade if exposed to prolonged heat above manufacturer rating or to certain solvents; no documented leaching of harmful compounds from food-grade silicone mats at normal baking temperatures, but older or damaged mats may release trace oligomers (short silicone chains) under stress.
Mold and bacterial growth
If not dried thoroughly or stored in damp conditions, silicone mat surfaces can harbor mold or bacteria in seams or textured areas; this is a maintenance issue, not an inherent material hazard, and is easily prevented with proper cleaning and drying.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastics
Silicone does not break down into microplastics like thermoplastics do. Wear and tear may produce microscopic silicone particles, but these are not classified as environmental or health hazards in the same way plastic microplastics are.
Source, EPA ↗Heavy metals
No recalls or testing reports of lead, cadmium, or other heavy metals in commercial food-grade silicone mats from major brands. FDA-approved food-grade silicone does not typically require added metal catalysts or pigments that pose contamination risk.
Source, FDA ↗Volatile organic compound (VOC) off-gassing
Cured silicone mats do not off-gas formaldehyde, VOCs, or odorous compounds at room temperature or during normal baking; initial smell when new is minimal and dissipates quickly.
How is this PFAS grade calculated?
The brand's record and disclosure
All-Clad is owned by Groupe SEB and maintains a kitchen-product focus with modest transparency on material safety. The brand does not publish detailed chemical composition disclosures for ancillary items like prep mats, but has no documented recalls or safety controversies tied to silicone baking products. Crate & Barrel carries several silicone kitchen items under the All-Clad name without public safety flags.
How it compares in its category
Silicone mats show lower concern than parchment paper (which can contain PFAS treatments in some brands) and non-stick coated baking sheets (which risk Teflon-type coating fume release at high heat). They avoid the microplastic risk of plastic liners and require no chemical pre-treatment like wax paper. The main trade-off is durability and staining over years of use, not chemical safety.
If you buy it
Hand wash with warm soapy water and air dry; avoid abrasive scrubbers that damage the surface. Do not exceed 500F (check product label for exact limit); most silicone mats are rated to 480-500F according to manufacturer specifications. Replace if the surface becomes sticky, tears, or develops permanent discoloration (signs of degradation), though this typically takes 5+ years of heavy use. Store flat or rolled to prevent permanent creasing.
