SUPCASE · Waterproof Phone & Tech Cases
Supcase iPhone 14 Pro Max 6.7 Inch Unicorn Beetle PRO Rugged Case-Green Fog - New Electronics | Color: Green
Lower PFAS risk phone case, but brand discloses nothing about materials.
Supcase Unicorn Beetle uses TPU and polycarbonate, materials not typically treated with PFAS. Brand provides no PFAS disclosures or certifications, so verification is limited.

The full breakdown
What it's made of and why it matters
This Supcase case combines thermoplastic polyurethane (TPU) as the flexible outer layer with polycarbonate (hard plastic) as the inner frame. Neither material is known to leach hazardous chemicals under normal room-temperature phone use, unlike some older plastics. TPU is engineered to resist degradation from typical phone heat and day-to-day handling. The 'Green Fog' color is a dyed polymer matrix; no dyes in phone cases are regulated the way azo dyes are in textiles, though dye safety in consumer plastics remains understudied.
The brand's record and disclosure
Supcase publishes no material safety data sheets or certifications (ISO, CPSIA, or similar) on its website; this is standard for the phone accessory market and does not indicate a safety failure. The company has no documented product recalls or chemical safety controversies on public record. No independent testing or third-party certifications specific to this case model are available in consumer databases. Absence of disclosure is typical for this category but means chemical composition claims cannot be independently verified.
How it compares in its category
Rigid phone cases made from TPU/polycarbonate blends are among the lowest-risk protective cases because they avoid metal components, coatings, and adhesives prone to leaching. Most competing rugged cases (OtterBox, Spigen, Lifeproof) use identical TPU/PC chemistry. Cases with fabric linings, metal accents, or epoxy coatings introduce marginally higher hazard complexity. This product sits squarely in the mainstream safety profile for drop-protection cases.
If you buy it
Rinse the case under cool water before first use to remove any residual manufacturing dust or mold-release agents. Avoid prolonged exposure to direct sunlight (UV degrades TPU over years) or heat above 60 degrees Celsius (TPU can soften). Replace if visible cracks, cloudiness, or permanent deformation appears, as structural failure increases phone damage risk. Wipe with a damp cloth; do not soak or use harsh solvents, which can degrade polymer bonds.
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.”
Volatile organic compounds (VOCs) / off-gassing from manufacturing
TPU and polycarbonate may emit trace VOCs during or immediately after manufacturing. Supcase does not publish outgassing data. Risk is minimal in typical use (outdoor phone case) but brief odor upon unboxing is not unusual and typically dissipates within days.
Dye and colorant safety (Green Fog pigmentation)
No regulatory body restricts dyes in phone case plastics as strictly as textile or cosmetic dyes. No heavy metal contamination or azo-dye concerns are documented for mainstream phone case manufacturers. Supcase does not disclose pigment source or testing.
Microplastics release from mechanical wear
Repeated flexing or abrasion of TPU can generate fine plastic particles, particularly at case edges. These particles shed into the environment but do not enter the body through normal phone case handling. Risk is negligible compared to plastic textiles or food-contact items.
Polymer degradation and leaching under thermal stress
TPU and polycarbonate are stable at normal ambient temperatures and standard phone operating heat (up to 45 degrees Celsius typical use). No established leaching of BPA, phthalates, or other endocrine disruptors has been reported from TPU/PC phone cases under normal conditions.
Mold or bacterial growth in protective recesses
Phone cases with raised bezels and textured interiors can trap moisture and dust if not dried after exposure to water or sweat. This is a hygiene concern, not a chemical hazard, but regular rinsing and air-drying mitigates risk entirely.
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.
