SPIFR #3 Plastic Fire Retardant Closed-End Zipper

As a precision-engineered fastening component, this Size 3 plastic flame-retardant closed-end zipper delivers rigorously verified fire resistance and structural reliability—positioned to meet the stringent safety demands of global industrial, commercial, and consumer markets.

Features

1. Verified High-Temperature Flame Retardancy

• No Combustion or Molten Dripping: The component remained free of ignition, melting, and dripping—eliminating the risk of secondary thermal injury or fire propagation.
• Immediate Fire Suppression: After-flame time was measured at 0 seconds, ensuring rapid extinguishment upon flame removal.
• Minimal Structural Impact: Char length was limited to 3mm (well within acceptable thresholds), with no separation of components; the zipper retained full functional integrity for smooth opening and closing post-testing.
  This performance fully satisfies the critical requirement: "No melt/drip, no separation, no ignition, and remains functional."

2. Closed-End Structure: Stability & Security

• Secure Fixation: Prevents unintended disengagement, making it ideal for flame-retardant bedding (pillowcases, duvet covers), protective apparel, and emergency gear—ensuring consistent shielding against environmental hazards.
• Structural Durability: Molded as a single unit with the zipper assembly, the closed-end base eliminates loose components, reducing the risk of breakage or failure during repeated use.
• Fabric Compatibility: The compact, low-profile design seamlessly integrates with lightweight to mid-weight fabrics (including cotton, polyester blends, and flame-retardant textiles) without compromising comfort or product aesthetics.

3. Industrial-Grade Durability & Longevity

• Resilient Componentry: Engineering plastic teeth feature precise meshing to resist wear, deformation, and tooth detachment—maintaining performance through thousands of opening/closing cycles.
• Robust Tape Construction: Woven from high-tensile polyester-cotton fabric, the tape retains its flame-retardant properties through repeated laundering, with no stiffness, fraying, or degradation in harsh environmental conditions (moisture, mild chemical exposure).
• Ergonomic Slider: The ABS slider is engineered for consistent, jam-free operation, with a textured surface to facilitate secure grip and easy manipulation—even in low-visibility or gloved-hand scenarios.

4. Global Compliance & Environmental Safety

• Eco-Friendly Formulation: The halogen-free, low-formaldehyde flame-retardant system adheres to international environmental standards (including EU REACH and US CPSIA), ensuring safety for long-term skin contact and intimate use in bedding and apparel.
• Market Compatibility: The zipper’s performance aligns with global safety regulations for protective products, enabling seamless integration into supply chains targeting European, North American, and Asian markets.

Applications

• Protective workwear (kitchen, industrial, and cleanroom apparel)
• Flame-retardant bedding (hospital, hotel, and nursing home linens)
• Emergency and disaster-relief gear (sleeping bags, escape capes)
• Light industrial storage solutions (tool bags, equipment covers)
