Casebus IP68 Waterproof Phone Case, Underwater Snorkeling Case, Inflated Touchscreen for Diving
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic case with waterproof membrane, 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’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Elastomer membrane degradation and leaching under UV/heat
Polyurethane or TPE membranes can degrade when exposed to prolonged UV, heat, or chlorine/salt, potentially releasing oligomers or plasticizers if seals fail. This is a durability rather than acute toxicity risk, but extended sun storage or hot-climate use may accelerate membrane embrittlement.
Microplastics
If the touchscreen membrane is repeatedly flexed or if the rigid case cracks internally during drops, microscopic plastic particles could enter water or be inhaled if the case fails during underwater use. Risk is low during normal use but increases with mechanical damage.
Source, EPA ↗Bacterial or mold growth inside sealed case
Moisture trapped inside the sealed case after submersion can promote bacterial or fungal growth if the case is not dried thoroughly before re-sealing. This is a hygiene concern rather than chemical leaching, but can cause odor or phone damage.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No test data or reports of lead, cadmium, or antimony in Casebus or competitor rigid phone case plastics exist in public records. This hazard class is not associated with modern polycarbonate or ABS phone cases in any regulatory or recall database.
Source, FDA ↗Adhesive or sealant off-gassing
Phone case assemblies may use epoxy or silicone adhesives in seam construction, but sealed design and low surface area mean volatile organic compound exposure is negligible. No odor complaints or chemical sensitivity reports for this product line are documented.
The full breakdown
What it's made of and why it matters
This case is constructed from rigid plastics (likely polycarbonate or ABS) with an internal waterproof membrane seal system that creates the IP68 rating. The sealed architecture means the case material does not contact food, skin for prolonged periods, or drinking water, limiting leaching pathways for common plastic contaminants. The touchscreen membrane is typically a thermoplastic polyurethane or similar thin elastomer layer designed to transmit touch signals while maintaining water resistance. No coating or chemical treatment is described, so hazards from adhesives, dyes, or surface treatments are not documented for this product line.
The brand's record and disclosure
Casebus is a consumer electronics accessories brand with no public safety certifications, recalls, or formal disclosures regarding material composition or chemical testing. The brand provides no sustainability statement, PFAS commitment, or third-party testing documentation in available product marketing. No major safety incidents or complaints specific to this brand's phone cases have been widely reported. Lack of transparency is typical for mass-market phone case manufacturers, but also means no reassurance beyond the structural design itself.
How it compares in its category
Waterproof phone cases are inherently lower-risk than food-contact or heating cookware because they isolate the user from the plastic interior through sealed design and brief contact. Most competitors (OtterBox, Spigen, Catalyst) use similar rigid plastic and elastomer membrane systems with equally minimal chemical disclosure. This product's IP68 rating and inflatable touchscreen feature are standard engineering approaches that do not introduce novel chemical risks. The main differentiator in this category is seal integrity and durability over time, not chemical composition.
If you buy it
Inspect the seal gasket and membrane for cracks before submersion, and replace the case if seals degrade visibly, as waterproofing failure is the primary safety concern (water damage to the phone, not chemical leaching). Rinse the external case with fresh water after saltwater or chlorinated pool use to prevent salt/chlorine accumulation and membrane brittleness. Do not expose the case to prolonged direct sunlight or heat above 140 F (60 C), as elastomer membranes can degrade or become less flexible. Store in a cool, dry place when not in use; check seals annually if used frequently for snorkeling or diving.
