F · High PFAS

Skip until Storm Case discloses waterproof treatment chemistry.

Verdict: SkipPolypropylene hard case poses minimal non-PFAS chemical risk if uncoated; waterproof treatment chemistry unknown, request disclosure before purchase.

Storm Case does not disclose what coating or treatment makes this case waterproof. Hard cases often use water-repellent coating or polymer treatments that may contain PFAS, but specifics are unavailable.

The full breakdown

What it's made of and why it matters

Storm Case Condition 1 is constructed from polypropylene (PP), a thermoplastic polymer widely used in protective cases because it resists impact and moisture naturally. The 'waterproof' designation indicates an additional surface treatment or sealant applied to seams and joints; the specific chemistry of this treatment is not disclosed publicly. Uncoated or minimally treated PP itself is chemically stable and does not leach known toxins under normal storage conditions. However, the waterproofing agent, likely a polyurethane coating, silicone elastomer, or proprietary hydrophobic resin, is the actual unknown variable.

The brand's record and disclosure

Storm Case has not published material safety documentation or ingredient disclosure for its waterproof treatments. No third-party certifications (e.g., Cradle to Cradle, RoHS, or material transparency standards) are evident in publicly available sources. The brand does not proactively communicate about chemical composition, PFAS avoidance, or testing results on their product line. Without direct contact with the manufacturer, the waterproofing method remains a significant opacity.

How it compares in its category

Hard protective cases in this size and durability range typically use bare polypropylene (Pelican, Apache) or polycarbonate (Hardigg). Those brands often disclose material specs and some provide PFAS-free or Teflon-type coating-free certifications. Storm Case's silence on waterproofing chemistry positions it below transparency leaders, though not uniquely so in the budget/mid-tier case market. Comparable cases at similar price points equally lack disclosure.

If you buy it

Store in cool, dry conditions away from direct sunlight to prevent polymer embrittlement; polypropylene degrades under sustained UV exposure. Do not expose to prolonged heat (>70°C/158°F) as the waterproof coating may soften or off-gas. Inspect seams and closures annually for cracking or separation, which degrades waterproofing integrity. If the waterproof coating odor is pungent when first opened, ventilate outdoors for 24-48 hours to allow volatile compounds to disperse.

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.”

Possible

Volatile organic compounds (VOCs) from unknown waterproof coating

Polyurethane, silicone, or hydrocarbon-based waterproofing treatments can off-gas formaldehyde, isocyanates, or other organics during manufacturing and initial use. Storm Case does not disclose the waterproofing chemistry, so the presence and levels are not confirmed but plausible in sealed case manufacturing.

Possible

Coating adhesion and microparticle shedding

If the waterproof coating is not chemically bonded to polypropylene (which has low surface energy), it may degrade, flake, or shed microparticles into stored contents over years. No published durability or adhesion testing is available for this product.

None known

Polypropylene polymer stability over time

Polypropylene itself does not leach BPA, phthalates, or heavy metals under typical storage conditions. No recalls or chemical-safety issues specific to Storm Case polypropylene cases have been documented in public records.

None known

Heavy metal contaminants in pigments or additives

No reports of lead, cadmium, or antimony in Storm Case hard cases. Polypropylene used in protective cases is typically virgin or recycled-certified resin without known contaminant issues, though manufacturer testing data is not public.

Possible

Waterproof treatment leaching into contents (water exposure)

If the case is submerged or subjected to prolonged water contact and the waterproof coating fails or degrades, small amounts of hydrophobic additives could theoretically migrate into water-sensitive contents. Risk is low for dry storage but unquantified under field conditions.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
