Spigen A611p Waterproof Float Case
Waterproof case coating unknown. Spigen silent on PFAS.
Spigen A611p uses TPU plastic with waterproof treatment but discloses no PFAS details. Waterproof coatings often contain fluorochemicals; lack of transparency raises concern.

The full breakdown
What it's made of and why it matters
The Spigen A611p is constructed from thermoplastic polyurethane (TPU), a flexible plastic polymer chosen for impact absorption and water resistance. TPU itself is generally considered safer than rigid plastics for device protection because it does not readily leach BPA or phthalates under normal use conditions. However, the product includes a waterproof coating or treatment (composition unspecified by Spigen) that may contain fluorinated compounds to achieve water repellency; these coatings are where PFAS chemicals commonly hide in protective cases.
The brand's record and disclosure
Spigen is a major accessory manufacturer with no publicly documented safety recalls or regulatory actions specific to this case model. The brand maintains minimal transparency on material composition and chemical treatment processes; no independent certification (such as Oeko-Tex or similar) is advertised for this product. Spigen has not issued public statements regarding PFAS avoidance or use of fluorine-free water-repellent alternatives, placing it in the silent category on this issue.
How it compares in its category
Waterproof phone cases typically rely on either TPU seals with coated edges or fully fluorinated polymer treatments to achieve water resistance. The Spigen A611p sits in the mainstream budget-to-mid-range segment; competitors like OtterBox and LifeProof offer similar TPU-based designs with equally opaque coating disclosures. Cases marketed as PFAS-free or using non-fluorinated water-repellent finishes remain uncommon and rarely specified at point of sale, so this case does not stand out as uniquely risky within its category.
If you buy it
Do not expose the case to prolonged heat above 60 degrees Celsius (140 Fahrenheit), as TPU can soften and degrade, potentially releasing coating compounds. Rinse periodically with plain water and mild soap to avoid salt or chlorine buildup in seals; air-dry completely before storing. Replace the case if seals crack, waterproof seal integrity appears compromised, or the exterior coating begins flaking or peeling. Keep the case away from direct sunlight for extended periods, as UV exposure can accelerate TPU degradation.
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.”
PFAS in waterproof coating
Waterproof coatings on TPU cases often contain fluorinated compounds (PFAS) to achieve water repellency. Spigen does not disclose coating chemistry or certify PFAS avoidance for this model, making it impossible to rule out.
TPU thermal degradation and leaching
TPU itself is stable under normal conditions, but heating above 60 degrees Celsius can initiate polymer breakdown, potentially releasing oligomers or plasticizers. This is most likely if the case is left in a hot car or near direct heat sources.
Coating adhesion and particle shedding
Waterproof coatings can delaminate or flake over time, especially if the case flexes repeatedly or is exposed to UV. Small particulate shedding is cosmetic in most cases but could theoretically introduce coating fragments into contact with skin or food.
Microorganism growth in seals
Waterproof cases trap moisture in seals and crevices if not dried thoroughly after water exposure. Prolonged dampness can encourage bacterial or mold growth in inaccessible areas, though this is a hygiene concern rather than a chemical toxicity risk.
Heavy metals in colorants
No safety recalls or testing data on record for heavy metal contamination in Spigen case pigments. Standard TPU formulations do not typically contain cadmium or lead, but independent verification for this specific product is unavailable.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
