SUPCASE Unicorn Beetle Pro Rugged Case for iPhone 16 Pro
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPU, polycarbonate, and elastomer blend, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What SUPCASE Unicorn Beetle Pro Rugged Case is made of, ingredients and materials
The Unicorn Beetle Pro uses thermoplastic polyurethane (TPU) combined with polycarbonate and elastomer blends. TPU is inherently flexible and durable, making it ideal for impact absorption without requiring water-repellent coatings. Polycarbonate adds rigidity and scratch resistance. Neither material requires Teflon-type coating, silicone coatings, or other chemical surface treatments for water resistance; the case relies on seals and material density instead. This design choice avoids the most common chemical concerns in rugged phone cases.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Elastomer and TPU off-gassing
TPU and some elastomer blends can release volatile organic compounds (VOCs), particularly in new cases or if exposed to heat. Odor typically dissipates within days to weeks; ventilate the case outdoors when new and avoid placing it in direct sunlight during storage.
Material degradation and microplastic shedding
TPU and polycarbonate can degrade over years of sun exposure, flexing, or contact with oils and solvents. While the case is not intended for ingestion, microscopic fragments from worn seals or edges could theoretically accumulate in pockets or on hands; this risk is low but increases with age.
Seal integrity and bacterial growth if moisture trapped
If water enters the case or moisture becomes trapped between the case and phone, prolonged dampness can support bacterial or mold growth on the phone or interior surfaces. This is not a defect in the case itself but a consequence of any sealed enclosure; dry the phone and case promptly after water exposure.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Polycarbonate itself does not inherently contain lead or cadmium. SUPCASE does not disclose pigment sources or heavy-metal testing; no recalls or reports exist for this product line. Risk is assessed as very low for normal handling.
Source, FDA ↗BPA & bisphenols
Although polycarbonate can contain BPA, direct skin contact with a phone case presents minimal ingestion or dermal absorption risk. No reports of BPA or BPS issues from SUPCASE rugged cases exist. Risk is negligible because the case does not hold food or liquid and contact is brief and external.

The brand's record and disclosure
SUPCASE does not publicly disclose material safety certifications or PFAS testing results on this product. The brand has no known recalls or toxicity incidents associated with the Unicorn Beetle Pro line. Transparency about chemical composition is limited, but absence of reported problems in this product category over many years of sales suggests no widespread health flagging. No third-party certifications (e.g., OEKO-TEX, Cradle to Cradle) are marketed for this case.
How it compares in its category
Rugged phone cases typically compete on drop protection and water sealing. The Unicorn Beetle Pro's dual-material construction (TPU plus polycarbonate) is standard among mid-to-premium rugged cases; brands like OtterBox and Spigen use similar blends. Unlike some competitors, there is no indication SUPCASE applies water-repellent coatings to this model, reducing chemical exposure risk. Cases in this price tier rarely undergo independent toxicity testing, so the Unicorn Beetle Pro is neither better nor worse documented than alternatives.
If you buy it
Avoid prolonged direct sunlight or extreme heat above 60C, as TPU can soften and degrade over time. Clean the case regularly with a damp cloth and mild soap; do not use solvents or abrasive cleaners that may weaken seals or material bonds. Replace the case if seals crack, material yellowing becomes visible, or the frame loses structural rigidity, typically after 2-4 years of heavy use. Inspect the rubber gaskets annually to ensure water resistance remains intact.
