Fixed Wasserdichtes Telefon
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes on phone case, 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.
Polymer off-gassing and volatile organic compounds (VOCs)
New rigid polycarbonate and TPU cases may emit low levels of volatile monomers (BPA, styrene) in closed spaces or when warm. Fixed brand has not disclosed material sourcing or manufacturing limits; baseline risk is low for external phone cases with minimal skin contact, but sealed packaging may trap odors on first opening.
Gasket and seal material degradation
Waterproof seals typically use nitrile or silicone rubber. Over 2-3 years of heat cycling and UV exposure, these can harden and lose water-blocking ability, but this is a functional failure rather than a chemical hazard; no documented leaching of heavy metals or endocrine disruptors from Fixed gaskets.
Microplastics
Over extended use, rigid case edges and snap closures can crack or shed small fragments, especially if dropped repeatedly. This is a physical durability issue, not chemical, but fragments should not be ingested; no evidence Fixed cases use recycled plastics with contamination, though the brand does not specify virgin versus recycled material sourcing.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Flame retardants
Rigid polycarbonate cases may contain antimony trioxide as a flame retardant, which is regulated but poses no risk in an external case with no skin contact or food use. No specific data for Fixed products, and the sealed design limits any migration pathway.
Source, EPA ↗Adhesive or solvent residues in seams
Injection-molded cases use minimal adhesive; snap closures are mechanical. Fixed does not list adhesive-assembly steps in public specs. No adhesive-related incidents reported for this brand or product line.
The full breakdown
What it's made of and why it matters
Fixed Wasserdichtes is a rigid waterproof phone case; the material composition is not publicly detailed by the brand, but waterproof phone cases in this category typically use injection-molded polycarbonate, TPU (thermoplastic urethane), or polypropylene with mechanical seals (gaskets, snap closures) rather than chemical coatings for water resistance. This mechanical waterproofing approach means chemical leaching from protective surface treatments is not a concern, and the case does not rely on Teflon-type coating or other fluorinated polymers for its function. The sealed design also minimizes contact between the phone and case internals with food or skin during typical use.
The brand's record and disclosure
Fixed is a Czech electronics accessories maker with a modest but stable presence in European mobile protection markets. The brand has not published safety certifications (OEKO-TEX, CPSIA, RoHS statements) or made any public PFAS disclosure or commitment. No major product recalls or chemical contamination incidents are on record for Fixed phone cases. The silence on chemical composition is typical for the budget-to-mid-tier phone case market and does not indicate a known safety problem, but reflects limited transparency as a smaller regional player.
How it compares in its category
Waterproof phone cases compete on seal integrity, drop protection, and material durability rather than chemical hazard profiles. Fixed sits in the conventional segment, mechanical sealing with rigid polymers, no special coatings advertised. Premium brands (Lifeproof, OtterBox) and budget competitors (generic polycarbonate cases) use similar material strategies. The absence of any advertised water-resistant coating or nanotech finish on the Fixed product actually reduces chemical risk compared to cases claiming 'advanced polymer coatings' or hydrophobic surface treatments, which may contain PFAS or volatile monomers.
If you buy it
Rigid polycarbonate and TPU cases do not degrade significantly from normal phone heat (up to 45-50 C daily use), but avoid prolonged sunlight or enclosed hot cars to prevent stress cracking over years. Inspect gasket seals every 12-18 months for hardening or visible gaps; if seals lose elasticity, water resistance drops. Clean case interior dry before reinstalling phone to prevent trapped moisture and mold growth on the phone itself. Case material is not food-contact, so standard precautions for phone cases apply; cleaning with standard soap and water is a common practice.
