Booe Waterproof Phone Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes silicone and TPU, 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 Booe Waterproof Phone Case is made of, ingredients and materials
Booe's waterproof phone case uses silicone and TPU (thermoplastic polyurethane), both synthetic polymers chosen for flexibility, water resistance, and temperature stability. Silicone is inert and rarely leaches under normal use; TPU can degrade under prolonged UV or heat but not at temperatures encountered in phone case service. The waterproofing comes from mechanical seals and material density, not chemical coatings, which eliminates common hazards from water-repellent surface treatments.
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.
TPU degradation over extended UV exposure
TPU can yellow and lose flexibility after 1-2 years of outdoor use or direct sunlight, potentially compromising the seal. This is a material property of TPU, not a chemical toxin, but affects product lifespan and waterproof performance.
Microplastic shedding from TPU
As with all TPU products, micro-wear particles can shed during regular use, handling, and mechanical stress. This is an environmental and ingestion concern if particles enter water or food, though phone case contact with food is atypical.
Mold or bacterial growth in seals (maintenance-dependent)
If the case remains wet or damp without drying, organic growth can occur in seal crevices. This is not a chemical hazard but a hygiene concern; regular inspection and air-drying prevent this.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Silicone off-gassing (minimal)
Silicone does not off-gas volatile organic compounds under normal conditions; medical-grade and food-contact silicones are well-established as chemically inert. No hazard is documented for consumer silicone phone cases.
Heavy metals
No testing or recalls indicate heavy metal contamination in silicone or TPU phone cases from this brand. Unless colored dyes are used, risk is lower; silicone and TPU accept pigments with lower concern when sourced from regulated suppliers.

The brand's record and disclosure
Booe has no public record of safety certifications, material disclosures, or chemical transparency statements. The brand has not issued PFAS statements or sought third-party testing credentials (ISO, FDA, CE mark details are not documented). No recalls or safety controversies are documented for this product line. Absence of disclosure does not indicate a hazard, but it means claims about material sourcing cannot be independently verified.
How it compares in its category
Waterproof phone cases typically use silicone, TPU, or combinations thereof; Booe's material mix is standard for the category. Unlike some competitors that add hydrophobic coatings (which may contain PFAS or other repellents), this case appears to rely on bulk material properties. This approach has lower concern than cases with applied surface treatments, though it offers no advantage over other seal-based competitors in chemical concern.
If you buy it
Avoid prolonged exposure to direct sunlight, as TPU can yellow and become brittle over 1-2 years of intense UV. Inspect seals periodically for cracks or separation; replace the case if waterproofing integrity is visibly compromised. Clean with mild soap and water; do not use harsh solvents or abrasives. Store in a cool, dry place and avoid extreme heat (above 60°C), which can accelerate polymer degradation.
