Nanuk 920 Camera Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polypropylene copolymer shell, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Foam padding decomposition or off-gassing
Interior foam is typically polyethylene or polyurethane and is not chemically characterized by Nanuk. In sealed, warm storage, foam can degrade slowly; inspect after years of use and replace if discoloration or odor develops.
Rubber gasket degradation
Gasket material (likely neoprene or EPDM) can crack or harden with age or heat exposure, compromising waterproofing but not releasing toxins. This is a functional failure, not a chemical hazard.
Plastic off-gassing or odor
New polypropylene cases may emit minor volatile odors for the first few weeks due to residual mold-release agents or processing oils; this is not toxic but may be noticeable in sealed storage. Air the case before first use with sensitive optics.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No printed warnings or labels on the Nanuk 920 are documented to contain lead or cadmium inks. If applied, modern screen-printed logos are typically low-risk, but direct contact with printed areas during prolonged storage is not a concern for this product class.
Source, FDA ↗Migration into stored contents
Polypropylene shell does not leach BPA, phthalates, or other chemicals into dry electronics or optics under normal use. No chemical exposure pathway exists between the case and expensive gear stored inside.
The full breakdown
What it's made of and why it matters
The Nanuk 920 shell is injection-molded polypropylene copolymer, a thermoplastic with no inherent phthalates, BPA, or heavy metals in the base resin. Polypropylene is chemically stable at room temperature and does not leach into contents under normal use. The interior foam padding is separate from the shell and not fused; the case itself presents minimal exposure risk to stored items like cameras, lenses, or electronics.
The brand's record and disclosure
Nanuk (owned by Plastifoam Company) has not published formal safety certifications, material disclosures, or PFAS statements as of available public record. The company focuses on durability marketing rather than chemical transparency. No product recalls or safety controversies are documented for this model. Lack of disclosure does not indicate a problem, but reflects the typical silence of rugged case manufacturers on materials.
How it compares in its category
Rigid polypropylene cases like the Nanuk 920 have lower concern for some flame retardant additives compared to soft-sided nylon cases that may contain flame retardants or dyes. They are comparable to other rigid polypropylene alternatives (Pelican, Storm Case) in material safety profile. Unlike metal cases, polypropylene avoids risk of rust or electrostatic discharge. The sealed gasket system relies on mechanical design, not waterproof coatings, eliminating coating-degradation or leachable concerns.
If you buy it
Store dry electronics and avoid prolonged exposure to direct sunlight or heat above 60°C to prevent polymer stress. The foam interior absorbs moisture; dry the case fully after wet use and leave it open to air occasionally to prevent mold growth in the foam, not the shell itself. Inspect the rubber gasket annually for cracks or warping; replace if visible damage occurs. Clean the exterior with mild soap and water; avoid solvents that could degrade the polypropylene over time.
