Are natural-colored nylon cable ties fireproof? Many people mistakenly believe that any nylon cable tie with a high flame-retardant rating is inherently "fireproof."
Flame-retardant rating: Mainstream natural-colored ties comply with the UL94 V-2 standard; some high-end or custom versions can achieve V-1 or V-0 ratings (which must be explicitly specified).
Self-extinguishing time: After the ignition source is removed, the flaming combustion time is ≤30 seconds.
Dripping behavior: Molten droplets are permitted during combustion, and these droplets may ignite cotton wool placed underneath (this is the key distinction between V-2 and V-0/V-1 ratings).
Material nature: Nylon 66 is a combustible engineering plastic; its ability to self-extinguish upon removal from the flame relies on added flame retardants, meaning it is not an "incombustible" material.
