No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
The iPhone 16 Mod NX Black combines silicone (soft elastomer) and thermoplastic (rigid plastic backing) in a common two-layer protective case design. Silicone itself has no established leaching hazards under normal use; thermoplastic is typically polypropylene or polystyrene, neither of which leaches BPA, phthalates, or other endocrine disruptors at room temperature. The case does not employ Teflon-family coating coatings or Teflon-type coating-based treatments, eliminating fume risk on heating.
The brand's record and disclosure
Rhinoshield does not publicly disclose material testing, third-party certifications, or chemical composition details on this product. No recalls, safety incidents, or contamination events are documented for this specific case model in public records. The brand's silence on PFAS stance is typical for phone case manufacturers and does not indicate use; absence of Teflon-family coating chemistry claims aligns with industry standard for silicone-thermoplastic cases.
How it compares in its category
Phone cases using silicone and thermoplastic are among the lowest-hazard protective accessories on the market. This case avoids heavier risks present in metal cases (nickel dermatitis), fabric cases (formaldehyde resins), or cases with adhesive coatings (volatile off-gassing). Rhinoshield's design is functionally identical to numerous mid-range competitors; material hazard profile is standard for the category.
If you buy it
Store away from direct sunlight and heat (silicone can degrade faster with UV exposure, and thermoplastic may warp above 60 degrees Celsius prolonged). Clean with mild soap and water; avoid solvents that may crack or soften the thermoplastic. Replace if the case shows cracking, separation of layers, or loss of grip, as protective function is compromised. Inspect regularly for trapped moisture, which can damage the phone rather than the case itself.
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.”
Silicone degradation over time
Silicone can lose elasticity and develop surface cracking after 12-24 months of regular use and UV exposure, reducing shock absorption. This is wear-related, not chemical leaching, and does not pose direct safety risk to skin or phone contents.
Thermoplastic brittleness at low temperature
The rigid plastic component may become brittle and crack if exposed to freezing temperatures for extended periods, though this does not release hazardous chemicals. Practical concern only in extreme cold environments.
Adhesive outgassing from layer bonding
No volatile organic compound (VOC) or formaldehyde off-gassing is documented for Rhinoshield cases. Adhesive used to bond silicone to thermoplastic in standard phone cases is minimal and fully cured; no reported odor or respiratory issues.
Heavy metal contamination in pigment
Black colorant in silicone and thermoplastic is typically carbon black or approved organic dye. No cadmium, lead, or other heavy metals are known to be present in black phone cases from established manufacturers like Rhinoshield.
Bacterial growth in case crevices
Silicone cases trap moisture and organic matter in seams and grip ridges, which can harbor bacteria and mold if not cleaned regularly. Risk is environmental contamination of case surface, not chemical leaching into phone or hands.
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.
