Ghostek Google Pixel 6 Waterproof, NAUTICAL slim
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes thermoplastic elastomer (TPE), 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 Ghostek Google Pixel 6 NAUTICAL slim is made of, ingredients and materials
This case is thermoplastic elastomer (TPE), a synthetic rubber polymer that is inherently water-resistant without added coatings. TPE does not require Teflon-type coating, PVC plasticizers, or fluorinated treatments to achieve its waterproof rating, which relies instead on material density and precision sealing around ports and buttons. TPE is chemically inert once cured and does not typically leach into food or skin contact under normal phone-case use. No glazes, enamels, or ceramic coatings are present that would introduce lead or cadmium risk.
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.
TPE material degradation over time
Thermoplastic elastomers can stiffen, crack, or lose water-seal integrity after 2-3 years of use or exposure to UV light and heat. Cracks allow liquid ingress and may expose phone electronics.
Port seal leakage if improperly maintained
Dust, lint, or dried adhesive in charging or audio ports can prevent seals from seating correctly, compromising waterproof rating. User responsibility to clean ports before sealing case.
VOC or odor off-gassing
New TPE cases may emit a faint plastic odor for the first few weeks as residual volatile compounds dissipate. This is cosmetic rather than a health hazard but indicates incomplete curing or lower-grade polymer.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
TPE does not typically contain BPA or plasticizers of concern. No lead, cadmium, or antimony hazards are known for this material class in phone cases under normal use.

The brand's record and disclosure
Ghostek has no public PFAS disclosure or third-party certification (e.g., Cradle to Cradle, OEKO-TEX) on record for this model. The brand does not appear in major chemical-hazard recalls or litigation databases for phone cases. Ghostek's website does not detail material sourcing or safety testing for the Nautical line, which is typical for mass-market case makers but limits independent verification of supply-chain practices.
How it compares in its category
Waterproof phone cases typically use TPE, silicone, or polyurethane, all of which avoid Teflon-type coating-based coatings. The Nautical slim sits in the mainstream segment; some premium competitors (e.g., OtterBox Defender, LifeProof) publish more detailed material specs and certifications, while budget alternatives may use lower-grade TPE or undisclosed rubbers. TPE cases are generally less prone to odor or off-gassing than polyurethane, making this material a lower concern choice for these specific issues.
If you buy it
Keep the case dry internally by shaking out moisture after submersion and allowing it to air-dry completely before use. Avoid prolonged exposure to direct sunlight or heat above 60°C (140°F), which can degrade TPE elasticity over time. Inspect seals and gaskets annually for cracks or hardening; replace the case if seals no longer compress or if water begins to seep in. Hand-wash with soap and water; do not use solvents, bleach, or harsh cleaners, which can weaken TPE.
