Fire retardant brush filament is used in the strip brushes of major shopping malls, screen doors, escalators, etc. The strip brush with fire retardant brush filament can play the role of dustproof and fire retardant. What kind of fire retardant brush filament can delay the fire speed?
Fire retardant brush filament is divided into grades: V0, V1, V2. The V0-level brush filament material can achieve a better fire retardant effect. The V0 grade brush filament is subjected to two 10-second burning tests, and the fire is extinguished within 30 seconds without burning characteristics. After the V1 brush filament is subjected to two 10-second burning tests, the fire is extinguished within 60 seconds, and no burning material can fall. After the V2 brush filament was subjected to two 10-second burning tests, the fire was extinguished within 60 seconds, and burning materials fell.
The fire retardant brush filament is mainly artificially synthesized from nylon 6 and PP materials, using non-halogen fire retardant materials, low smoke, low toxicity, and fire retardant effect reach EU environmental protection standards. The produced brush filament is smooth and balanced, the brush filament is stable, and the body is tight and straight. It prevents the waste and loss of the fire retardant brush filament thread brush due to the irregular brush filament discharge during the production and processing.
