Nanuk · Waterproof Camera & Lens Protection Cases
NANUK 935 Pro Photo Kit
Low-medium risk. Hard case likely made of PP, no water-repellent coating needed.
This rigid polypropylene case uses rubber gasket seals for waterproofing. No PFAS disclosures found, and standard hard cases typically avoid PFAS, leaving only minor uncertainty.

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.
Microbial/bacterial growth in seals
Waterproof gasket channels can accumulate moisture and trap organic matter if not rinsed periodically, creating conditions for mold or bacterial biofilm; this is a maintenance issue, not a material hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Polypropylene thermal degradation
PP is stable at room temperature and typical storage conditions; no off-gassing of volatile organic compounds (VOCs) or monomers is documented for this product line.
Gasket material leaching
Rubber and silicone gasket seals are chemically inert in contact with air and dry storage environments; no established leaching into food or sensitive items is reported.
Impact-induced particulate release
Polypropylene does not brittle-fracture into sharp microplastics; cracks are typically large and contained within the case structure.
Heavy metals
No credible reports exist of cadmium, lead, or antimony colorants in Nanuk cases; polypropylene injection molding uses FDA-compliant pigment packages for consumer hard goods.

What it's made of and why it matters
The Nanuk 935 is injection-molded polypropylene (PP), a thermoplastic chosen for rigidity, impact resistance, and chemical inertness. PP is a rigid plastic with lower concern for certain chemicals, it is not a material linked to BPA, phthalates, or other endocrine disruptors under normal use. The waterproof gasket seals are typically rubber or silicone compounds; these are stable and not known to off-gas volatile compounds at room temperature.
The brand's record and disclosure
Nanuk is a Canadian hard-case manufacturer with no established history of chemical safety disclosures, certifications (e.g., ISO, GOTS), or recall actions related to material hazards. The brand's silence on PFAS and material composition is typical for the category but represents a lack of transparency rather than a known problem. No credible reports of toxicity or off-gassing have surfaced in consumer feedback or media.
How it compares in its category
Hard protective cases (Pelican, Storm Case, Nanuk) present lower concern than soft fabric luggage or foam-lined alternatives, which may contain flame retardants or formaldehyde resins. Polypropylene shells are more inert than ABS or polycarbonate alternatives. The main trade-off is that rigid cases are less recyclable and heavier; chemical safety is not a differentiation point in this segment.
If you buy it
Store in a dry, well-ventilated space; no special precautions needed for the case itself. Avoid prolonged exposure to direct sunlight or temperatures above 60°C (140°F), as polypropylene can soften and warp but will not off-gas toxins. Check and rinse gasket seals annually to prevent mold or bacterial growth in the seal channels. Replace the case if cracks or stress fractures appear, as they compromise the waterproof integrity.
