2 Pack Waterproof Compatible With Samsung Galaxy Smarttag2 Holder, Tpu
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPU (thermoplastic 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.
Microplastic shedding or particle release
Thin-walled TPU can shed microscopic fibers if rubbed or flexed repeatedly over years. Risk is minimal for a protective case with low friction use, but not zero. No quantification available for this specific product.
Seal degradation and water infiltration
Gaskets and adhesive seals are the failure point in waterproof cases. Over 2-3 years, elastomers harden and adhesives degrade, leading to leakage rather than chemical release. Not a toxicological hazard but a warranty and product-life issue.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Standard TPU formulations used in phone accessories do not routinely contain BPA or phthalates. No reports of leaching into food, skin, or liquids from TPU cases in normal use.
Source, FDA ↗Flame retardants
TPU used in phone accessories is not typically flame-retardant treated; no antimony or halogenated additives are reported for this category. Cases are not subject to flammability standards.
Source, EPA ↗Off-gassing of volatile organics from molded TPU
TPU cases do not produce reportable off-gas emissions under normal storage or use conditions. Any initial plastic odor dissipates within days and is not associated with toxic compound release.
The full breakdown
What it's made of and why it matters
This case is TPU (thermoplastic polyurethane), a flexible plastic polymer that does not contain BPA, phthalates, or other common plastic additives of concern in its base formulation. TPU achieves waterproofing through its inherent material properties and physical seals (gaskets, closure design) rather than fluorinated coatings or water-repellent finishes. The two-pack design suggests standardized injection molding with no glazes, enamels, or adhesive layers known to leach heavy metals or volatile organics. No fabric or textile components are mentioned, eliminating formaldehyde or azo-dye risks.
The brand's record and disclosure
Samsung has not published a specific PFAS stance or public testing data for this smarttag holder accessory. The company does not list this product in any major chemical disclosure programs (Cradle to Cradle, GreenGuard, etc.), nor has it reported use of intentional PFAS Teflon-family coating in TPU smartphone cases. Samsung's silence on PFAS for accessories is typical of the industry and does not indicate a known problem, only lack of transparency.
How it compares in its category
TPU cases dominate the waterproof accessory market and are generally considered lower-risk than silicone (which may use antimony catalysts), rubber, or thermoplastic elastomers with added flame retardants. Unlike some rigid polycarbonate or ABS cases with coated surfaces, TPU's waterproofing does not rely on applied finishes that degrade or flake. Price and durability will vary by thickness and seal quality, but material hazard profile is well-established as benign for short-contact use.
If you buy it
Rinse the case with fresh water after saltwater or chlorine exposure to prevent salt crystallization in seals. Avoid prolonged storage in direct sunlight or heat above 60°C (140°F), which can soften TPU and reduce waterproof integrity. Replace the case if seals crack, become opaque, or detach; degraded cases will leak rather than emit harmful vapors. Clean interior surfaces and allow full air-dry before storing to prevent mold or odor accumulation.
