Rhinoshield · Waterproof Personal Electronics Cases
iPhone 17 Pro Max SolidX
Phone case; typical TPE has low PFAS risk but no brand disclosure available.
Rhinoshield SolidX is a protective phone case made from TPE. No public PFAS claims or certifications from brand; material choice suggests lower concern, though confirmation would require direct inquiry.

Why this grade
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Category baseline
other is a category where PFAS exposure is more common.
The full breakdown
What it's made of and why it matters
The SolidX case is TPE (thermoplastic elastomer), a synthetic rubber-plastic hybrid chosen for shock absorption and grip. TPE does not rely on phthalate plasticizers in most modern formulations, though some older TPE blends contained them. This material class is not associated with lead, cadmium, BPA, or volatile off-gassing typical of low-cost PVC or PU alternatives. The risk profile is primarily around proprietary additives and colorant safety, which are not publicly disclosed by Rhinoshield.
The brand's record and disclosure
Rhinoshield is a protective case manufacturer with a minimal public safety footprint. No third-party certifications (e.g., RoHS, REACH, ISO 14001) appear on their published materials. The brand has not issued statements on chemical content, heavy metals in dyes, or PFAS use in manufacturing or finished products. No recalls or formal safety complaints are documented in public databases, though absence of disclosure does not confirm absence of risk.
How it compares in its category
Phone cases made from TPE sit in the mid-safety range for protective accessories. They are generally safer than budget PVC or vinyl cases (which may contain phthalates and cadmium) but less transparent than cases carrying third-party certifications (e.g., GreenGuard, Cradle to Cradle). Silicone alternatives often have better disclosure practices. The SolidX offers similar chemical risk to other unbranded TPE cases; differentiation is minimal without independent testing.
If you buy it
Avoid prolonged exposure to direct heat (vehicle dashboards, direct sunlight for extended periods) as TPE can soften and leach colorants above 60C. Clean with mild soap and water; do not use aggressive solvents or high-heat dishwashers. Replace if the material shows visible cracking, discoloration, or sticky residue, as these indicate polymer degradation. Store in cool, dry conditions to extend lifespan and minimize off-gassing of volatile additives.
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.”
Colorant heavy metals (cadmium, lead)
No recalls or documented contamination for Rhinoshield products. TPE manufacturing standards in established markets typically exclude these metals, but no third-party testing is publicly available for this specific case.
Phthalate plasticizers
Modern TPE formulations used in phone cases rarely include traditional phthalates (DEHP, DBP), but Rhinoshield does not publish material certifications. Risk is low for this material class but unconfirmed.
Volatile organic compound (VOC) off-gassing
TPE cases may release low levels of volatile additives (accelerators, flame retardants, antioxidants) in their first weeks, particularly when new or stored warm. Rhinoshield provides no off-gassing data; effect is typically mild odor and minimal health impact with normal use.
Thermal instability and leaching
TPE softens above 50-60C. Prolonged heat exposure may cause colorants or processing additives to migrate onto skin or device screen, particularly with darker or vibrant colors. Risk escalates if case is stored in hot vehicles.
Degradation and microparticle shedding
Over 1-2 years of use, TPE can develop micro-tears and shed small fragments, especially at stress points. These particles are unlikely to be toxic but represent physical wear; replacement is a practical rather than safety issue.
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.
