Good Cook · Silicone Cutting & Prep Boards
Good Cook Flexible Cutting Board Set
Flexible boards are usually silicone, lower PFAS risk than nonstick cookware.
Good Cook flexible boards are typically silicone or TPR rubber, materials not known to contain PFAS.

What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Polymer thermal degradation and particle shedding
Silicone and TPR rubber can soften, warp, or shed microscopic particles when exposed to sustained heat above recommended limits or through repeated flexing over years. No specific temperature threshold for Good Cook boards is published; users should assume these materials are not appropriate for direct contact with surfaces above 350-400F.
Bacterial and mold colonization
Flexible boards with textured or porous surfaces may trap food particles and moisture in small crevices, creating conditions for bacterial or mold growth if not dried promptly. TPR rubber surfaces are particularly prone to this; regular sanitization and air-drying between uses is critical.
Surface discoloration and staining
User reports on retailer sites indicate that Good Cook flexible boards stain easily from beets, turmeric, and tomato products and do not wash clean after prolonged contact with acidic or pigmented foods. While staining is cosmetic, it may correlate with material porosity or absorptive properties relevant to contamination risk.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Leachables from TPR rubber (if used)
If the product uses TPR rather than food-grade silicone, TPR can contain zinc, plasticizers, or other additives. No specific contamination has been documented for Good Cook boards, but product labeling does not explicitly confirm which material is used in each board size.
Heavy metals
Colored silicone or rubber products can contain cadmium, lead, or other heavy metals in pigments used for color. No testing or recalls have been published for Good Cook boards; silicone products from reputable suppliers typically avoid this, but brand certification status is unknown.

What it's made of and why it matters
Good Cook Flexible Cutting Board Set is constructed from silicone rubber or TPR (thermoplastic rubber), both of which are food-contact polymers with different safety profiles. Silicone is chemically inert at typical kitchen temperatures and does not degrade easily under normal use. TPR rubber, while more prone to wear, is not known to leach problematic chemicals during food contact at room temperature or mild heating; the main concern with TPR is surface degradation and particle shedding over extended use rather than chemical migration.
The brand's record and disclosure
Good Cook is a private-label cookware brand with no published material safety certifications, third-party testing transparency, or explicit disclosure of chemical composition beyond generic marketing claims. The brand has not issued public statements on PFAS use or sourcing standards. No significant safety recalls specific to cutting boards have been documented in CPSC records for this brand, though this absence does not constitute affirmative safety testing.
How it compares in its category
Flexible silicone or TPR cutting boards occupy a lower-risk position compared to glazed ceramic or wooden boards that may harbor bacteria, and far lower risk than nonstick cookware coated with Teflon-family coating. They sit roughly equal to uncoated plastic cutting boards in chemical hazard profile, though silicone is generally preferred over polycarbonate (BPA-prone) or older plastics. The flexible design itself poses no chemical advantage; durability and replacement frequency matter more than material type for overall safety.
If you buy it
Avoid prolonged contact with hot oils or surfaces above 400F (silicone and TPR can soften at extremes). Hand wash or use cool machine cycles; dishwasher heat may accelerate polymer degradation and surface breakdown. Inspect regularly for tears, discoloration, or sticky residue indicating material breakdown; replace if visible wear exposes substrate or if surface becomes rough. Store away from direct sunlight and heat sources to extend usable life and minimize off-gassing.
