SPIFR #3 Plastic Fire Retardant Closed-End Zipper

Can the zippers on your sleeping bag or workwear withstand 260°C high temperature? This Size 3 plastic flame-retardant closed-end zipper, tested at 260°C for 5 minutes by SGS, works perfectly even after heating! Whether for kitchen work, home emergencies, or commercial workwear, its safety performance is proven—total peace of mind!

Lab Test Scene: This Zipper Is Incredibly Rugged!

• Flame Resistance: No ignition or molten dripping—regular plastic zippers soften at 150°C, but this one barely smokes, completely eliminating the fear of "high-temperature molten plastic burns."
• Structural Stability: After heating, the closed-end bottom box didn’t crack, and the teeth didn’t fall off; it slides as smoothly as new. With a char length of only 3mm (half the size of a fingernail), there’s almost no damage.
• Safety Response: Extinguishes instantly on flame contact (0-second after-flame time)—even if it accidentally touches sparks, it goes out immediately, leaving no chance for fire.

The Closed-End Design Is So Practical—Fits All Scenarios!

• Home Emergency Enthusiasts: Sew it onto your home sleeping bag or escape cape! The sealed closed-end structure keeps sparks out and smoke at bay, making midnight emergency escapes safer. Pair it with a kitchen apron—no fear of zipper melting when oil splatters, adding an extra layer of protection for daily cooking.
• Catering/Service Industry Workers: My company’s workwear uses this zipper! It stays securely closed during running or cleaning—no accidental slipping. After more than ten washes, the zipper is still smooth, and the tape hasn’t frayed—much more durable than regular zippers we used before.
• Hotel/Nursing Home Buyers: We purchased this in bulk for bedding and workwear. The closed-end design makes it easy for staff to put on and take off, and none have broken after bulk washing. With the SGS test report, we can just present it during audits—saving a lot of hassle.

Daily Use Details Are a Big Plus!

• Comfortable to Use: The slider is lightweight—easy to pull with one finger, even with thin gloves. Perfect for the elderly and employees.
• Versatile Colors: Available in black, white, navy, light gray, etc.—sews onto workwear or sleeping bags without looking awkward, matching the overall design.
• Eco-Friendly & Safe: No odor, non-irritating for intimate wear. Safe for families with children and the elderly, complying with international environmental standards.
