Wilton · Silicone Baking Molds
Vintage Wilton Silicone Teddy Bear Cupcake Molds Cups Liners Beige Set
Silicone cupcake molds carry lower PFAS concern, but Wilton discloses nothing.
Silicone is inherently PFAS-free by chemistry, making this product lower risk for cupcake baking. Wilton provides no PFAS transparency; verify retailer documentation if concerned about coatings.

The full breakdown
What it's made of and why it matters
This product is food-grade silicone, a synthetic polymer prized for heat stability and non-stick properties. Silicone does not leach aluminum, lead, or cadmium like glazed ceramics or vintage enameled cookware, and it lacks the Teflon-type coating (Teflon) coating that can degrade and release fumes at high heat. Silicone's chemical stability means it resists degradation during normal baking use at typical oven temperatures (up to 400-500 degrees Fahrenheit).
The brand's record and disclosure
Wilton is a major U.S. baking supplies manufacturer with decades of presence in retail and does not publicly disclose detailed material certifications or third-party testing for chemical contaminants. The company has no established recalls or documented contamination incidents for silicone baking molds. However, Wilton maintains minimal transparency on PFAS, phthalates, or manufacturing process controls, which is typical for the category but limits independent verification of purity.
How it compares in its category
Silicone molds rank among the safest food-contact cookware options, superior to non-stick coated metals or ceramic glazes that may contain lead or Teflon-type coating. Versus paper liners (which can contain PFAS for grease resistance), silicone reusable molds eliminate that concern. Vintage silicone products of this age are generally stable, as silicone does not degrade significantly over decades under typical storage conditions.
If you buy it
Hand wash or use a gentle dishwasher cycle to preserve the mold surface; avoid abrasive scrubbing that could microscratches. Do not exceed manufacturer temperature limits (typically 400-500 degrees F); exceeding these temperatures theoretically increases risk of minor leaching, though silicone is far more thermally stable than Teflon-type coating. Check molds annually for visible discoloration, sticking, or odor changes as signs of degradation; replacement is inexpensive and risk of failure is low.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Silicone leaching (minor organic compounds)
Food-grade silicone is designed to minimize leaching, but trace oligomers (unreacted polymer chains) may migrate into fatty or acidic foods at high heat. This is far below levels of concern in normal home baking but is an inherent property of the material; risk is lowest at moderate temperatures (below 350 degrees F).
Teflon-type coating fume risk (from coating)
This product is solid silicone with no Teflon-type coating, eliminating the thermal decomposition hazard that affects non-stick metal cookware. No fume risk is documented for silicone molds even at high temperatures.
Lead or cadmium in colorants or additives
Food-grade silicone intended for the U.S. market is not documented to contain lead or cadmium; silicone manufacturing does not typically require heavy metal additives. Wilton's lack of explicit certification creates uncertainty, but no recalls or incidents establish a known risk.
Mold growth or bacterial contamination
Silicone's porous microstructure can harbor bacteria or mold if not dried thoroughly after washing, particularly in creases or seams. This is a hygiene issue rather than a chemical hazard; regular hot-water washing and air drying mitigate risk.
Coating degradation over time
Silicone is chemically stable and does not peel, crack, or degrade like ceramic glazes or enamel coatings. Vintage silicone molds of this type are unlikely to show significant degradation unless exposed to prolonged sunlight or extreme temperatures.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
