3M 7100072880 Flame Resistant Loop Fastener 5/8 in X 50 Yd

Product Description

The 3M 7100072880 is a flame resistant woven loop fastener supplied in a 50-yard roll, 5/8 inches wide, in beige. It is the loop component of the SJ3418FR reclosable fastener system and carries no adhesive backing. The material is nylon construction, preshrunk for dimensional stability, and rated to withstand temperatures up to 250 degrees F. It meets the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test requirement. Engaged thickness is 0.15 inches. This fastener is intended for garment, textile, and fabric applications where flame resistance is a regulatory or safety requirement.

This loop fastener is used in aerospace, transportation, and specialty garment fabrication where reclosable closure and flame resistance must coexist. Its woven nylon construction allows it to be sewn directly onto fabric panels without adhesive. The preshrunk finish ensures the fastener lies flat and holds dimensional tolerances after washing or dry cleaning, making it suitable for uniforms, protective gear, and upholstered components subject to repeated laundering or cleaning cycles.

Key Features

Compatibility

Mates with 3M SJ3419FR flame resistant hook fastener. Designed as the loop component of the SJ3418FR reclosable fastener system for use on garments, fabrics, and textile assemblies requiring flame resistant closures.

Installation Notes

This fastener is sewn onto fabric or textile substrates using standard industrial or commercial sewing equipment — no adhesive activation or heat bonding is required. Secure all thread ends and verify stitch integrity before use in any safety-rated application. Follow applicable aerospace or transportation authority guidelines when installing in regulated environments. Do not expose the fastener to open flame or temperatures exceeding its rated limit during installation or use.
