What Are The Performance Advantages of Halogen-Free Low-Smoke Flame-Retardant Wires?

The core performance advantages of halogen-free, low-smoke, flame-retardant wires lie in safety, environmental friendliness, and environmental adaptability, especially their ability to reduce hazards in extreme scenarios such as fires.

Core Safety Advantages in Fire Scenarios

This is its most critical performance highlight, directly related to personal safety.

Low-smoke characteristic: It produces minimal smoke when burning, with a smoke light transmittance usually ≥ 60%, maintaining a visible distance of over 60 meters. Even in case of fire, it reduces visibility obstacles and buys time for personnel evacuation and rescue.

Halogen-free and non-toxic: The material contains no halogens such as chlorine or bromine, and does not release highly corrosive and toxic gases like hydrogen halides (e.g., hydrogen chloride) when burned. These gases not only irritate the respiratory tract and cause suffocation but also corrode equipment, while this type of wire can significantly reduce such risks.

Strong flame retardancy: Its flame-retardant capability is enhanced through special processes (e.g., irradiation cross-linking). The wire can self-extinguish quickly after being away from the fire source, effectively preventing the spread of flames and slowing down the speed of fire expansion.

Environmental and Durability Advantages in Long-Term Use

Beyond extreme scenarios, its performance remains more stable during daily use.

Environmental compliance: It contains no heavy metals such as lead or cadmium, nor toxic additives. It causes little environmental pollution during production, use, and disposal, meeting the environmental requirements of modern buildings and electronic equipment.

Weather and corrosion resistance: The insulation layer is mostly made of materials like polyolefin, which has strong anti-aging and UV resistance capabilities. It can also withstand certain chemical corrosion, making it suitable for humid, dusty, or slightly corrosive environments.

High-temperature stability: Its operating temperature is generally higher than that of ordinary wires. Conventional products can withstand temperatures above 105°C, and some special models can reach 150°C. The insulation layer is less likely to soften or age when used at high temperatures for a long time.

Engineering and Practical Advantages

From the perspective of construction and long-term use, it also has obvious convenience.

Longer service life: With excellent anti-aging and environmental corrosion resistance, its service life can reach 70 years or more, matching the service life of buildings or large equipment and reducing later replacement costs.

Flexible installation: Some models (e.g., flexible wires) have good flexibility, making them easier to install in complex building wiring environments (e.g., narrow pipelines, multi-bend paths) and reducing installation difficulty.
