SPIFR #3 Plastic Fire Retardant Closed-End Zipper

Why This Zipper Is Non-Negotiable for Safety Gear
Lab-Validated Fire Resistance
We put this zipper through a 260°C, 5-minute extreme heat test—here’s what happened:
✅ No Ignition/Molten Dripping: Stays intact even when exposed to workshop sparks or kitchen oil splatters (eliminates burn risks for workers).
✅ Instant Self-Extinguishing: 0-second after-flame time—flame goes out immediately.
✅ Minimal Damage: Only 3mm of charring; the zipper remains 100% functional (no stuck teeth, no separation).
Closed-End Design for Workwear
- Secure Fit: Prevents accidental opening during fast-paced work (perfect for chef jackets, industrial coveralls, or lab coats).
- Gloved-Hand Friendly: Ergonomic ABS slider with non-slip texture—easy to pull even with thick work gloves.
- Fabric Compatibility: Seamlessly sews into flame-retardant fabrics (canvas, polyester blends) without bulking or discomfort.
Durability That Cuts Costs
- Engineering Plastic Teeth: Resist wear, deformation, and tooth loss.
- Washable Tape: Retains flame-retardant performance after 20+ industrial washes (no fraying, no stiffness).
- Corrosion-Resistant: Metal-free construction—no rust in humid or chemical-exposed work environments.
