Case Study: Advancing Zipper Performance for Fire-Resistant Gear
Client
- A global supplier of turnout gear, wildland firefighting suits, and industrial FR coveralls.
Challenge
- Gear had to meet NFPA 1971 and UL certification for flame resistance, radiant-heat exposure, and after-flame time.
- Design needed to avoid added bulk or snag risk during rapid don/doff scenarios.
Solution
- Developed a heat-treated brass tooth zipper system with a corrosion-resistant finish for bleach-laundered gear.
- Certification samples passed UL testing on the first submission, eliminating resubmission delays.
Outcome
- Customer released its new bunker-gear line three months ahead of schedule.
- Distributor feedback cited a 30% reduction in zipper-related returns.
- Compliance pedigree opened new international markets in the EU and Middle East.
