Galaxy S25 Ultra Waterproof Case, Rugged Full-Body Armor
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polymer 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 Galaxy S25 Ultra Waterproof Case, Rugged is made of, ingredients and materials
This case is constructed from a rigid polymer (likely polycarbonate, thermoplastic polyurethane, or a blend). Polymer phone cases pose minimal chemical risk to skin or food contact, since they are not applied to food-facing surfaces and contact only the device and user's hands. The sealing integrity for waterproofing relies on the polymer's inherent density and the mechanical fit of gaskets and closures, not chemical coatings. No internal off-gassing or leaching hazards are typical of well-manufactured polymer cases used at room temperature.
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.
Polymer off-gassing at elevated temperature
Rigid polymers may release volatile organic compounds if exposed to heat above 50-60C; typical room use poses no risk, but prolonged car dashboard or direct sunlight exposure could cause minor off-gassing.
Bacterial or mold growth in seals if moisture trapped
Waterproof cases can trap moisture between the gasket and phone surface if not dried after water immersion; stagnant moisture may promote microbial growth, though this is a hygiene rather than chemical hazard.
Microplastic shedding from case degradation
Over 2-3 years of heavy use, rigid polymer cases may develop micro-scratches or stress cracks; small fragments could theoretically shed, though risk of ingestion is very low for a phone case.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leachables from gasket or closure materials
Silicone or rubber gaskets used in seals are not known to leach hazardous substances into skin or water at room temperature; no specific reports for Rugged Armor product line.
Heavy metals
Polymer casings may contain color additives; cadmium or lead-based dyes are largely phased out in reputable manufacturers, and this product category does not typically report contamination.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Rugged Armor has not issued a public statement on PFAS or other chemical disclosures for this product line. The lack of a stated warranty or third-party certification (such as ISO 9001 or materials safety data sheets) limits visibility into material sourcing and quality controls. No safety recalls or adverse event reports are publicly associated with Rugged Armor phone cases based on available records. The brand's silence on chemical safety is typical of the mass-market phone accessory category but leaves no independent verification.
How it compares in its category
Waterproof phone cases are generally lower-risk consumer products because they are not in sustained contact with food, skin for extended periods, or inhalable materials. This Rugged Armor case is structurally comparable to OtterBox Defender and similar rigid polymer designs; the main differentiator is build quality and seal durability, not chemical safety. Cases using proprietary hydrophobic coatings (rare in rigid cases but sometimes found in fabric-lined models) would pose higher PFAS exposure risk; this product shows no evidence of such treatment. Polymer cases inherently avoid the lead and cadmium risks found in ceramic-glazed dishware or some metal-rimmed alternatives.
If you buy it
Keep the case away from prolonged direct heat sources above 60C (140F), as polymer may soften or off-gas volatiles at elevated temperatures. Check the gasket seals monthly for dirt, salt residue, or cracks; clean with fresh water and allow to air-dry before closing, especially after saltwater or pool use. Replace the case if the seal becomes permanently loose, the polymer develops stress fractures, or the port covers no longer close fully. Do not attempt to repair or modify the case with adhesives or coatings, as this may introduce undisclosed chemicals and compromise waterproofing.
