Caudabe Sheath Samsung Galaxy S26 Ultra case
Lower concern. TPU phone cases typically free from PFAS, but Caudabe provides no disclosure.
Caudabe Sheath uses TPU, a material not known to require PFAS. The brand doesn't publicly confirm PFAS absence and no independent testing exists.

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.
Volatile organic compounds (VOCs) from residual solvents
Polyurethane coatings may retain residual solvents after manufacturing. A temporary chemical smell when unboxed is normal and dissipates within hours to days. No data suggests harmful exposure from brief handling, but strong persistent odor warrants airing.
Microplastic shedding from coating degradation
If the coating peels or cracks over time, small polyurethane fragments may shed onto hands or skin. This is a physical fragmentation risk, not a chemical hazard, but replacement is advisable once visible wear occurs.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Phthalate esters in polyurethane coating
No phthalates have been reported in Caudabe cases or typical TPU phone case coatings. Modern polyurethane formulations for consumer electronics avoid restricted phthalates, though full ingredient disclosure from Caudabe is absent.
Heavy metals
No recalls or reports exist for Caudabe cases containing lead, cadmium, or chromium. TPU formulations for consumer goods typically use benign organic or inorganic pigments, though Caudabe provides no material safety data sheets.
Source, FDA ↗Skin sensitization from coating resins
Polyurethane is a known contact allergen in rare cases, but phone case coatings are fully cured and do not typically trigger reactions. No adverse events have been documented for Caudabe Sheath users, and risk is negligible with normal brief contact.
The full breakdown
What it's made of and why it matters
Caudabe Sheath uses thermoplastic polyurethane (TPU) shell with a polyurethane coating. TPU is a flexible synthetic polymer chosen for shock absorption and durability in phone protection. Unlike rigid plastics, TPU does not contain BPA or BPS by design, and polyurethane coatings on phone cases are not typically formulated with hazardous phthalates at concentrations of concern for brief skin contact. The material is inert when intact and does not leach into food or water.
The brand's record and disclosure
Caudabe is a consumer electronics accessories brand with no documented safety recalls, certifications, or public statements on material testing or chemical content. The company provides no transparency regarding PFAS, heavy metals, or manufacturing process controls. This silence is typical for phone case manufacturers but leaves consumers without independent verification of coating composition or quality assurance standards.
How it compares in its category
Phone cases occupy a low-risk product category because exposure is primarily external contact with intact surfaces, not ingestion or prolonged skin contact. TPU-based cases like Sheath present lower concern than cases with unknown rubber or vinyl compounds that may off-gas odors or contain legacy additives. Silicone cases offer similar safety profiles; leather cases avoid synthetic polymer concerns but cost more. Hard plastic cases (polycarbonate) carry no added chemical risk but offer less shock protection.
If you buy it
Inspect the case before use for any strong chemical smell, which would indicate excess residual solvents from manufacturing. Wipe it with a damp cloth if odor is present. Do not heat the case or leave it in direct sunlight for extended periods, as TPU can soften above 60, 70°C. Replace if the coating cracks, peels, or becomes sticky, as degraded surfaces may shed microparticles. Normal use and handwashing require no special precautions.
