Case-Mate Waterproof Floating Pouch 2-Pack
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polyurethane, 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.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Polyurethane degradation and microparticle shedding
Polyurethane can degrade under UV exposure or extreme temperature cycling over years of use, potentially releasing small polymer fragments. No documented health incidents from floating pouches are on record, but prolonged UV exposure in storage should be minimized.
Microplastic leaching from worn seams
If seams or the pouch material degrades significantly after extended use, small particles may shed into water or contact items inside the pouch. This is a wear-related failure, not an acute chemical hazard, and typically occurs only after years of heavy use.
Bacterial or mold growth if inadequately dried
Any sealed pouch that retains moisture creates an environment where bacteria or mold can grow, particularly in warm climates. This is a maintenance issue, not a material toxicity issue; regular drying prevents it.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Polyurethane does not typically contain lead, cadmium, or other heavy metal additives in consumer-grade pouches. No testing data is publicly available, but the material class does not require these metals for function.
Source, FDA ↗Adhesive or solvent residue from sealing
Modern polyurethane pouches are sealed via heat fusion or polyurethane adhesive, not solvent-based glues. No off-gassing or formaldehyde release is expected, and no incidents have been reported for this product.
The full breakdown
What it's made of and why it matters
Case-Mate's Waterproof Floating Pouch is constructed from polyurethane, a synthetic polymer that achieves waterproofing through material density and sealed seams rather than applied chemical coatings. Polyurethane is chemically stable under normal storage and use conditions, does not leach plasticizers like BPA or phthalates into the environment, and does not release volatile organic compounds (VOCs) at room temperature. The waterproofing comes from the material's inherent water-repellent properties and the pouch's sealed construction, not from PFAS-based water repellent treatments or fluorinated coatings.
The brand's record and disclosure
Case-Mate has not published a formal PFAS stance or chemical composition disclosure for this product line. No recalls, safety violations, or substantiated chemical hazard reports are on public record for this specific model. The brand's general approach to materials safety is not documented in widely available sources, meaning transparency on supply chain or testing is minimal. For personal electronics cases, Case-Mate operates in a category where chemical disclosure is not yet standard industry practice.
How it compares in its category
Waterproof pouches typically rely on either polyurethane, PVC, or silicone construction. Polyurethane is a middle-ground choice, more durable than uncoated PVC but less heat-resistant than silicone. Unlike some competitor pouches that may use Teflon-type coating or wax-based water repellent finishes, this polyurethane design does not require additional chemical coatings, which reduces potential exposure pathways. Most floating pouches in this price and durability tier use similar material profiles without documented hazard records.
If you buy it
Polyurethane pouches are not affected by heat in normal use (phones, keys, currency stored at ambient temperature). Avoid prolonged exposure to direct sunlight or extreme heat above 60 degrees Celsius, which can degrade the polymer over time and reduce water-resistance. Inspect seams and zippers annually for wear; degraded seams allow water ingress and are a functional (not chemical) failure point. Rinse with fresh water after saltwater exposure to prevent mineral buildup on seals, and air-dry completely before storage to prevent mold growth inside.
