SUPCASE Unicorn Beetle PRO Rugged Case for Galaxy S25 Ultra
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPU, polycarbonate, synthetic rubber 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 a blend of TPU (thermoplastic polyurethane) and polycarbonate, both common elastomeric and rigid polymers in phone case manufacturing. TPU is valued for shock absorption and flexibility; polycarbonate provides structural rigidity. Neither material is inherently prone to leaching hazardous chemicals into food or skin contact under normal phone-use conditions, since the case does not contact food or prolonged skin exposure in typical use.
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.
Volatile organic compound (VOC) off-gassing
New TPU and polycarbonate cases may emit low levels of residual solvents or monomers during the first weeks of use, particularly in warm, enclosed spaces. This is not specific to SUPCASE and resolves quickly with ventilation.
Bacterial or mold growth in seals
Waterproof gaskets and seals can harbor moisture and microbes if the case is exposed to water repeatedly and not dried between uses. This is a maintenance issue, not a material toxicity hazard, and is managed by periodic drying and ventilation.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Plasticizer leaching from TPU
TPU formulations can contain phthalate or non-phthalate plasticizers, but leaching into skin or indirect food contact during phone use is not documented as a concern for this product class. SUPCASE has not disclosed specific TPU additives.
Microplastic shedding from wear
TPU and polycarbonate do not degrade into microplastics under normal phone case handling. Visible flaking would indicate defective manufacturing, not a material property.
Heavy metals
The Unicorn Beetle PRO is marketed in solid colors (black, blue, purple) typical of cases with standard plastic pigments. No colored inks or coatings are applied to the contact surface, minimizing pigment transfer risk.

The brand's record and disclosure
SUPCASE is a well-established phone accessory brand with no published recalls or chemical safety controversies on record. The company does not publicly disclose material sourcing, manufacturing certifications (ISO, REACH, RoHS), or PFAS avoidance statements. This silence is common in the phone case category and does not indicate a safety failure; it reflects minimal regulatory pressure on non-food, non-contact-intensive accessories.
How it compares in its category
Rugged TPU/polycarbonate cases like the Unicorn Beetle PRO represent a mainstream safety profile in the phone case market. They avoid PVC (which can off-gas plasticizers) and synthetic rubber blends are less prone to degradation than cheaper elastomers. Waterproof sealing is achieved via gaskets and material density, not chemical coatings, placing this case in the lower-hazard segment of the category.
If you buy it
Store and use the case in typical room conditions; TPU and polycarbonate are stable below 60 degrees Celsius, so avoid prolonged exposure to direct sunlight or hot vehicles. Replace the case if the TPU shows visible cracking or clouding, which signals polymer degradation and loss of protective fit. No special cleaning is needed beyond mild soap and water; do not use solvents or high-heat sanitization.
