What Lineman Storm Box - 24" Model 305, Navy is made of, ingredients and materials
The Lineman Storm Box 305 is constructed from polypropylene (PP), a thermoplastic polymer chosen for its rigidity, impact resistance, and inherent moisture resistance. The case includes a waterproof coating or treatment (type unspecified by Storm Case), which is critical to verify for PFAS content, as Teflon-family coating water-repellent coating finishes commonly contain PFAS. The pick-and-pluck foam interior is typically polyurethane or polyethylene foam, which are chemically stable under normal storage conditions.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Polypropylene thermal off-gassing
PP is stable under normal storage but can release volatile organic compounds if exposed to sustained heat above 70°C (e.g., in direct sunlight, vehicles, or near heat sources). This product is designed for storage, not high-temperature use, so risk is low under typical conditions.
PFAS
The coating type and chemical identity are undisclosed. Many industrial hard cases use Teflon-type coating-based or other Teflon-family coating water barriers known to contain PFAS; alternatives exist but are not confirmed here. This is the primary hazard requiring clarification from the manufacturer.
Source, ATSDR ↗Coating degradation and leachate exposure
If the waterproof coating deteriorates or flakes, small particles may be released, particularly if the case is washed or subjected to abrasion. Ingestion risk is minimal unless particles contact food or water, but inhalation of airborne fragments during handling is theoretically possible.
What’s reassuring
Antimony catalysts in polyester or polyurethane foam
The foam interior material is not specified; polyurethane foams sometimes contain antimony trioxide as a catalyst. No public record of contamination or antimony testing for Storm Case products exists, but manufacturer specification of foam type would clarify this.
Migration from printed or applied labels/adhesives
If the case includes printed branding, labels, or adhesive-backed materials, inks or adhesives could potentially leach under moisture or heat stress. No hazard reports specific to this model are on record.
How is this PFAS grade calculated?
The brand's record and disclosure
Storm Case does not publicly disclose material safety data, chemical composition, or PFAS testing results on this product line. No third-party certifications (ISO 14001, Cradle to Cradle, or OEKO-TEX) are advertised for the Model 305. The brand markets durability and USA manufacture but remains silent on hazardous substance policies, making independent verification of the waterproof coating formulation impossible without direct contact.
How it compares in its category
Hard protective cases in this price and size segment typically use polypropylene shells with either silicone-based or Teflon-family coating water barriers; this product is standard construction. Competitors like Pelican and Nanuk also use PP but have published limited material disclosures. Unlike chemical storage or food-contact containers, protective cases face lower regulatory scrutiny, leaving PFAS and coating composition largely unaudited across the category.
If you buy it
Store the case indoors at room temperature, away from direct sunlight and heat sources above 70°C, as polypropylene can soften and off-gas at sustained high temperatures. Do not wash the case with solvents or acetone; mild soap and water are recommended for cleaning. Inspect the coating annually for cracks, peeling, or discoloration, as degradation compromises waterproof performance and may expose the substrate. Before purchase, contact Storm Case directly to request SDS (Safety Data Sheet) or technical documentation confirming PFAS absence in the waterproof coating.
