Adjustable Breathable Silica Gel Sport Band for Samsung Galaxy Watch 8
Lower concern. Silica gel is not a material linked to PFAS.
Material as recorded is silica gel elastomer. Samsung has no PFAS statement on record. Silica gel is not a material linked to PFAS in its standard form.

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.
Azo dyes (colorants)
If the band is pigmented (especially dark colors), azo dyes may be present; however, well-manufactured silica gel bands use non-toxic pigments or carbon black. Samsung does not disclose dye chemistry, so risk cannot be ruled out but is not reported.
Flame retardants
Silica gel does not require flame retardants for intrinsic fire safety. If additives are present, they are not disclosed by Samsung and no independent testing is publicly available. Risk is low for a non-flammable elastomer in wrist-worn use.
Source, EPA ↗Microbial or allergenic buildup (maintenance-related)
Porous elastomer bands can trap moisture and harbor bacteria or fungi if not cleaned regularly, particularly in the textured sections. This is a use-related risk, not a manufacturing defect, and is mitigated by routine washing.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Silica gel elastomers do not typically require formaldehyde-releasing compounds for curing or finish. No formaldehyde exposure risk is documented for cured silica gel watch bands.
Source, ATSDR ↗Antimony in polyester
This product is silica gel elastomer, not polyester fabric, so antimony catalyst residues are not applicable.
The full breakdown
What it's made of and why it matters
This band is composed of silica gel, a synthetic elastomer made from cross-linked silicone polymers. Silica gel is chemically inert after curing and does not leach monomers or plasticizers under normal wear conditions, unlike PVC or latex alternatives. The material is chosen for wrist-worn products because it resists sweat, heat from skin contact, and flexing without degradation. Breathability is typically achieved through an open-cell or porous network in the gel matrix rather than chemical additives.
The brand's record and disclosure
Samsung does not publicly disclose detailed material safety or chemical composition data for watch band accessories on standard product pages. The company has no known recalls specifically tied to silica gel watch bands and no published independent certifications (e.g., Oeko-Tex, FDA material list) for this product line. Samsung's silence on PFAS in elastomer accessories is consistent with industry practice, as most silica gel formulations do not require PFAS for performance. No credible reports of harm from Samsung silica gel bands exist in consumer safety databases.
How it compares in its category
Silica gel sport bands have lower concern for phthalate risk compared to PVC, and lower concern for unknown additives compared to low-quality thermoplastic rubber. Genuine silica gel typically outperforms cheaper silicone or rubber imitations in durability and leach resistance. Most mainstream brands (Apple, Garmin, Fitbit) use similar silica gel or fluorosilicone formulations for sport bands. The main differentiator is manufacturing quality and supplier transparency, neither of which Samsung emphasizes publicly.
If you buy it
Clean the band regularly with mild soap and water to prevent bacterial or fungal growth in textured areas, especially if worn during sweating or sports. Avoid prolonged exposure to extreme heat (above 60 degrees Celsius / 140 degrees Fahrenheit) or direct sunlight for extended periods, as this can accelerate polymer aging. Replace the band if you notice visible cracking, stickiness, or discoloration, which signals breakdown of the elastomer matrix. Store unused bands in a cool, dry place away from oils, solvents, and direct sunlight.
