Flame-Retardant PTFE Cable Filler Meeting Strict Safety Standards

Building cables, power distribution cables, public facility cables and industrial safety cables have extremely strict fire protection safety standards. Cable internal filling materials are key components affecting cable fire resistance. Most traditional cable fillers are flammable organic materials, which will burn violently and produce a large amount of toxic smoke and molten droplets when encountering open fire, accelerating fire spread and causing secondary pollution and safety hazards. Flame-retardant PTFE cable filler has inherent non-flammable and fire-resistant characteristics, which can meet the highest industry fire safety standards, and is a high-safety filling material for fire-resistant and flame-retardant cables PTFE SHEET.

PTFE cable filler has inherent Class A fireproof performance, which is fundamentally different from additive flame-retardant fillers. The stable fluorocarbon molecular structure makes the material have ultra-high decomposition temperature, which cannot burn and support combustion in the air. When encountering high temperature and open fire, PTFE filler will not produce open flame combustion, no molten droplet dripping, and no flame spreading phenomenon. After leaving the fire source, it can automatically extinguish fire quickly, effectively inhibiting the spread of cable fire. This inherent flame retardant performance will not fail due to aging and loss of flame retardant additives, ensuring long-term stable fire safety of cables throughout the service cycle.

The low-smoke and non-toxic performance of PTFE cable filler further improves cable fire safety. In the event of a cable fire, traditional flame-retardant fillers will produce a large amount of toxic and harmful smoke, which will cause personnel poisoning and environmental pollution, and block escape routes. When PTFE material is heated and decomposed, it only produces non-toxic and non-corrosive gas, with extremely low smoke density, no toxic hazard, which is conducive to personnel evacuation and fire rescue, and meets the strict smoke toxicity safety standards of public building cables PTFE TUBE.

In high-temperature fire environments, PTFE cable filler can maintain structural stability and play a continuous protective role. Ordinary flammable fillers will burn and disappear quickly in fire, resulting in cable internal structural collapse and rapid breakdown of insulation system. PTFE filler can maintain a complete filling structure under high-temperature fire conditions, support the cable internal structure, prevent rapid spread of fire along the cable, and delay cable insulation failure time, gaining valuable rescue time for fire fighting and personnel evacuation. This excellent fire resistance and structural stability make it fully meet the strict safety requirements of fire-resistant cables used in high-rise buildings, subways, tunnels and industrial fire-proof areas.

With the continuous improvement of cable fire protection safety standards in the construction and electrical industry, flame-retardant PTFE cable fillers have been widely used in high-standard fire-resistant cables, low-smoke non-halogen flame-retardant cables and safety fire-proof cables. It effectively improves the fire safety level of power and communication systems, reduces fire hazards and secondary losses, and provides solid safety guarantee for the safe operation of urban public facilities and industrial electrical systems.
