What Samsung Galaxy Watch Ultra Trail Band is made of, ingredients and materials
The Galaxy Watch Ultra Trail Band is a fluoroelastomer and silicone composite, which are synthetic rubber materials chosen for durability, flexibility, and resistance to sweat and water. Fluoroelastomer (often sold under brand names like Viton) is chemically stable and does not off-gas volatile organic compounds under normal wear conditions. The water-repellent coating (water-repellent coating) finish is the chemical wild card, these coatings are historically associated with PFAS (PFAS "forever chemicals"), though modern formulations sometimes use non-PFAS alternatives that Samsung has not disclosed.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
water-repellent coating degradation and potential leachables
The water-repellent coating finish on this band is likely to be PFAS-based, though Samsung has not confirmed this. As the coating degrades with wear, sweat, and washing, release of treatment residues into skin contact cannot be ruled out, though migration under normal wear is expected to be minimal.
Microfiber or particulate shedding
As the water-repellent coating ages and degrades, microscopic particles of the treatment or elastomer surface may shed into skin contact, particularly during friction or cleaning. This is not unique to this product but is a known wear mechanism in synthetic sport bands.
Skin sensitization or contact irritation from band material or residues
Fluoroelastomer is generally biocompatible, but individual sensitivity to uncrosslinked oligomers in the elastomer or residual solvents from manufacturing has been reported anecdotally in sensitive populations. Samsung does not provide hypoallergenic certifications or sterilization protocols.
What’s reassuring
Formaldehyde / VOCs
Fluoroelastomer and silicone rubbers do not require formaldehyde resins or azo dyes in their synthesis; no recalls or documented contamination of Samsung watch bands with these chemicals have been reported.
Source, ATSDR ↗Flame retardants
Fluoroelastomer does not typically contain antimony trioxide or conventional flame retardants by design, as the material itself is fire-resistant. No antimony contamination in Samsung wearables has been publicly reported.

The brand's record and disclosure
Samsung has made no public statement about the specific chemistry of this band's water-repellent coating treatment or whether it contains PFAS. The company does not provide material safety data sheets for consumer wearables and has not committed to phasing out PFAS in accessories, unlike some competitors in the electronics and apparel space. This silence is not evidence of a problem, but it reflects a lack of transparency typical of Samsung's approach to wearable band chemistry.
How it compares in its category
Sport watch bands made from fluoroelastomer and silicone are industry standard for durability and show lower concern for microfiber shedding compared to plastic or fabric alternatives that may shed microfibers or contain other processing chemicals. Compared to leather bands (which may contain heavy metals in tanning) or cotton/polyester straps (which may carry formaldehyde resins), this composite is a lower-toxicity choice. However, most major manufacturers (Apple, Garmin, Fitbit) similarly do not disclose water-repellent coating chemistry, making this product typical rather than exceptional in transparency.
If you buy it
Rinse the band with fresh water after prolonged sweat or saltwater exposure to reduce buildup of salts and skin oils, which can degrade both the elastomer and the water-repellent coating over time. Avoid prolonged exposure to direct heat above 60°C (140°F) or harsh solvents, as these can accelerate coating breakdown and potential leaching of treatment chemicals. Inspect the band every 6-12 months for cracks, discoloration, or peeling of the water-repellent coating layer; replace if visible degradation occurs. Do not wear continuously for more than 12-18 hours per day to allow skin to breathe and minimize chemical contact duration.
