Skip until waterproof treatment chemistry disclosed.
Waterproof coating remains undisclosed in composition. Hard cases typically use water-repellent coating or polymer treatments that may contain PFAS, but specifics are unavailable.

Material

Lab data

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
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.
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.
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’s reassuring
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.
Heavy metals
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.

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.
