SPIFR #5 Plastic Fire Retardant Open End Zipper

Focused on harsh, high-wear/high-risk scenarios (metallurgy, chemical, mining), this Size 5 plastic flame-retardant open-end zipper combines reinforced structure + lab-verified performance to become a professional component for extreme working conditions.

Stable Protection in Extreme Environments (Test Data Support)

Passing SGS-CSTC’s 260°C/5-minute test, it fully meets heavy industry needs:

• High-Temperature Tolerance: No ignition or molten dripping in environments close to welding slag (≈250°C) or metallurgical workshops (≈200°C), avoiding the risk of "high-temperature molten plastic adhering to clothing."
• Structural Ruggedness: No separation between tape and teeth after testing; the zipper remains 100% functional—even in scenarios with frequent pulling or tool scratches in workshops, it won’t "burst open."
• High Safety Margin: 0-second after-flame time and 3mm char length (far below industry standards) provide extra safety buffer for workers.

Industrial-Grade Reinforced Structural Design

Multiple upgrades for rough operation in heavy industry:

• Reinforced Teeth: 20% thicker engineering plastic teeth with glass fiber reinforcement, 40% improved impact/deformation resistance to withstand tool collisions and heavy object extrusion.
• Upgraded Tape: high-strength polyester tape with double weaving + edge binding, 30% higher tear resistance, and tolerant of repeated cleaning with industrial oil and detergents.
• Optimized Slider/Bottom Piece: The slider has anti-slip granular texture for precise operation with thick work gloves; the open-end bottom piece uses a thickened plug pin, with over 2,000 plug-in cycles (less prone to breakage).

Adaptability to Harsh Working Conditions

• Corrosion Resistance: No metal components; no rust or oxidation in chemical workshops or high-humidity mining environments, with stable long-term performance.
• Stain-Resistant & Easy to Clean: The tape has oil-repellent treatment; industrial oil and dust can be removed by regular washing, maintaining zipper cleanliness and smooth operation.

Value Highlights for Industrial Scenarios

• Cost Reduction & Efficiency Improvement: Enhanced durability reduces zipper replacement frequency for workwear/equipment, indirectly lowering maintenance costs.
• Compliance Compatibility: Test results meet flame-retardant certification requirements for industrial protective apparel, directly compatible with safety-audited heavy industry workwear.
• Bulk Compatibility: Seamlessly sews with industrial fabrics (reflective strips, anti-static flame-retardant fabrics), adapting to mass production processes.
