Spigen Tough Armor · Waterproof Phone & Tech Cases
Spigen Galaxy S25 Series Case Tough Armor AI
Lower concern. Standard phone case materials unlikely to contain PFAS.
Spigen Tough Armor cases use TPU and polycarbonate, common protective materials without disclosed PFAS treatments. No public lab testing or PFAS claims available for this product line.

Category baseline
other is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This case combines thermoplastic polyurethane (TPU) and polycarbonate, both widely used in consumer electronics accessories. TPU is flexible and absorbs shock; polycarbonate provides rigid structural support. Neither material is known to leach harmful chemicals under normal room-temperature phone case use. The blend is designed to withstand drops and prolonged contact with skin without degradation under typical conditions.
The brand's record and disclosure
Spigen does not publicly release detailed material safety data sheets or third-party certifications for this specific case model. The company has no documented history of product recalls related to chemical hazards or material failures in phone cases. Spigen maintains a neutral stance on PFAS and does not advertise PFAS-free formulations, though phone case materials of this type are not considered a primary vector for PFAS exposure.
How it compares in its category
Phone case safety profiles vary little across brands when using standard TPU or TPU/PC blends. Spigen's Tough Armor line is competitively positioned; alternatives from OtterBox, Ringke, and Caudabe use similar material chemistries. Unlike fabric or coated cases, rigid TPU/PC blends have no surface treatments prone to flaking or off-gassing. Cost and drop protection differ; chemical hazard profiles are broadly comparable.
If you buy it
Clean the case occasionally with mild soap and water to remove accumulated dust and skin oils. Avoid prolonged exposure to direct sunlight or heat above 140 degrees Fahrenheit, as TPU can soften over time. Replace the case if the TPU becomes tacky, yellows significantly, or develops visible cracks that expose the phone. No special maintenance is required; standard phone case handling practices apply.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Microplastics from material degradation
TPU can degrade and fragment under prolonged UV exposure or repeated flexing, though no documented studies confirm microplastic shedding from phone cases into skin or ingestion pathways under normal use.
Volatile organic compounds (VOC) off-gassing
TPU/polycarbonate blends do not typically off-gas formaldehyde or other regulated VOCs at room temperature. No recalls or complaints on record for Spigen Tough Armor cases related to odor or chemical off-gassing.
Heavy metal contamination in colorants
Spigen cases use standard colorant systems for TPU and polycarbonate; no regulatory violations or elevated heavy metal levels have been reported. Phone case materials are not known vectors for lead or cadmium exposure in this product category.
Adhesive or coating breakdown over time
The case has no applied surface coatings or adhesives that could degrade and leach into skin contact. Material embrittlement may occur after 2-3 years of use, but this results in mechanical failure, not chemical hazard.
Allergic contact dermatitis from material contact
TPU and polycarbonate are well-tolerated by skin in phone case applications. No established allergenic residues or unreacted monomers are known to leach from cured TPU/PC blends at skin contact.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
