SPIFR #8 Plastic Fire Retardant Open End Zipper

Designed exclusively for heavy industry, large-scale equipment, and high-wear scenarios, this Size 8 large-specification plastic flame-retardant open-end zipper centers on "lab-verified adaptability to extreme environments". Featuring a reinforced and durable open-end structure, it balances robust protection with convenient operation, becoming a reliable supporting component for high-risk industries such as metallurgy, chemical engineering, and heavy machinery.

Ultimate Flame-Retardant Protection Backed by Authoritative Testing

• Extreme High-Temperature Protection: No ignition or molten dripping throughout the test, completely solving the industry pain point of "structural failure of large-specification zippers under high temperatures." Even in extreme scenarios such as welding slag splashing (≈250°C) and high-temperature radiation from chemical reactors, it effectively inhibits fire spread and avoids the risk of molten plastic burns.
• Superior Structural Stability: The Size 8 large-specification teeth are made of thickened engineering plastic + glass fiber reinforced material. After testing, there is no tooth detachment or tape tearing; the open-end plug-in bottom piece remains firm, and the zipper retains 100% smooth opening/closing functionality. With a char length of only 3mm (almost no visible damage), it does not affect subsequent high-intensity use.
• Rapid Safety Response: The average after-flame time is 0 seconds—extinguishing instantly upon flame contact, leaving no chance for fire spread. It provides a "millisecond-level" safety buffer for workers in high-risk operations, meeting the "safety redundancy" design requirements of heavy industry.

Industrial-Grade Practical Advantages of Open-End Structure

• Convenient Donning/Doffing & Maintenance: Suitable for products requiring full opening (e.g., heavy protective clothing, industrial equipment protective covers, large tool bags). The thickened plug-in bottom piece has moderate clamping force—operable with one hand even while wearing thick work gloves, improving efficiency by 50% for workers changing clothes or maintaining equipment.
• Anti-Misoperation Structural Design: The plug-in bottom piece is equipped with an anti-loosening buckle, preventing accidental zipper breakage due to collisions or pulls during operations. Meanwhile, the opening/closing damping is uniform, avoiding "jamming" or "automatic sliding open" issues.
• Large-Specification Compatibility: The upgraded width of Size 8 teeth and thickness of the tape fit thick flame-retardant fabrics (e.g., canvas, aramid composite fabrics). After sewing, it fits closely with the fabric without protrusions or discomfort, ensuring the sealing performance of protective clothing and the overall structure of equipment.

 Industrial-Grade Durability & Environmental Adaptability

• Reinforced Material Upgrade: Teeth are made of high-strength engineering plastic with anti-aging and UV-resistant additives, resisting embrittlement and breakage even after long-term exposure to industrial dust and oil. The tape uses high-strength polyester, processed with double-layer weaving + edge binding, increasing tear resistance and withstanding high-frequency washing in industrial washing machines and corrosion from chemical detergents.
• Harsh Environment Tolerance: No metal components—rust-free and oxidation-free in high-humidity, high-corrosion chemical workshops and mining environments, maintaining stable performance. The tape surface is treated with oil-repellent and stain-resistant coating, allowing quick wiping of industrial oil and dust to keep the zipper sliding smoothly.
