Kona Best BBQ Grill Mats with Holes

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.

Teflon-type coating fume inhalation risk (nonstick coating degradation)

Fiberglass mesh with unspecified nonstick coating exposed to high grill temperatures will eventually flake or off-gas. At >500F, Teflon-type coating (if present) releases toxic fumes (polymer fume fever, respiratory irritation). The perforated design increases surface area contact with heat. No coating specification allows for no preventive verification.

Fiberglass fiber shedding into food

Mechanical abrasion from food contact, dishwasher use, or coating degradation can liberate fiberglass fibers into grilled items. While not chemically toxic, ingested fiberglass poses physical irritation risk to mouth and GI tract. This risk increases as the mat ages and coating fails.

Nonstick coating flaking and ingestion

Unspecified nonstick coatings can chip or peel under thermal stress and mechanical wear. Small coating flakes may transfer directly to food. Unknown coating chemistry means you cannot assess the toxicity of flaked particles.

VOC off-gassing from coating binders

Low-cost nonstick coatings often contain solvent residues or epoxy binders that off-gas when heated. Outdoor grill use mitigates exposure, but covered or indoor grilling could concentrate fumes. No material data sheet available to assess binder chemistry.

Aluminum leaching (if fiberglass substrate is aluminum-backed)

Product does not explicitly state substrate material. If aluminum mesh is used beneath the fiberglass, acidic or fatty grilled foods could cause minor leaching, particularly at high temperatures. No evidence this product uses aluminum backing, but lack of disclosure prevents confirmation.
