Flame Retardant Zipper
Flame Retardant (FR) Zippers are specialized, high-performance fastening systems engineered to resist ignition and maintain structural integrity when exposed to extreme heat and open flames. Unlike standard fasteners, these zippers are constructed using inherently fire-resistant materials, such as 100% Aramid or Nomex® tape and high-temperature resistant resin teeth and sliders, to prevent the zipper from melting or contributing to the spread of fire.
Primarily utilized in Personal Protective Equipment (PPE) for firefighting, offshore energy, and tactical operations, these zippers are designed to meet rigorous international safety standards (such as NFPA 2112 or EN 469) to ensure the wearer can safely egress from hazardous environments without hardware failure.

Features and Comments of FR Zippers
Technical Features & Performance Standards
1. Superior Thermal Resistance & Safety Behavior
-
High-Temperature Threshold (260°C): These zippers are engineered to maintain structural integrity and functionality even when exposed to extreme ambient heat up to 260°C.
-
Carbonization Property: During exposure to direct flame, the zipper is designed to carbonize rather than melt.
-
Zero Melting Drops: The advanced material composition ensures there are no melting drops during combustion, preventing secondary burn injuries caused by molten plastic.
-
Self-Extinguishing Capability: The flame is extinguished as soon as the ignition source is removed, significantly reducing the risk of fire spreading across the garment.
2. Specialized Industrial Protection
-
Anti-Arc & Zero Ignition: Specifically designed for high-voltage environments, these zippers provide anti-arc protection and zero ignition performance to protect electrical utility workers.
-
Anti-Static Properties: The construction includes anti-static features to prevent spark discharge in volatile environments like oil refineries or gas plants.
-
High-Strength Mechanical Performance: Beyond thermal safety, the zipper exhibits excellent strength, ensuring it can withstand the mechanical stress of heavy-duty industrial or tactical use.
3. Durability & Material Integrity
- Permanent Flame Retardance: The fire-resistant properties are permanent and inherent to the material, rather than a temporary surface treatment.
- Industrial Washability: These zippers are fully washable and maintain their protective capabilities even after repeated high-temperature industrial laundering cycles.
- Aramid/Nomex Construction: Utilizing 100% Aramid or Nomex tape, these fasteners provide the highest level of heat-stable backing for specialized protective apparel.
