Halogen-free flame-retardant cable (such as UL3385 Tin Plated XLPE Insulated Wire, UL10588 Fire Resistant Wire, etc.) as a new generation of environmentally friendly cable, its core advantage lies in the complete innovation of material formula. Unlike traditional cables, its rubber compound completely discards halogens (such as chlorine and bromine) as well as heavy metal components like lead, cadmium, chromium and mercury, eliminating the introduction of harmful substances from the source. When a fire occurs, this type of cable does not produce worrying toxic smoke - it neither releases corrosive hydrogen halides nor generates lethal carbon monoxide, significantly enhancing safety in fire scenarios.
In terms of environmental protection performance, this product strictly adheres to the strict standards of international environmental protection regulations. The concentration of hydrogen halide gas produced after its combustion is extremely low, and it is always controlled below 100PPM after detection. The light transmittance of the burning smoke remains above 60% to ensure the visibility of the escape route. It is particularly worth noting that its control over heavy metal residues has reached an almost strict level: take lead as an example, the residue is limited to below 90PPM, a value far below the industry's conventional requirements, fully demonstrating its environmentally friendly characteristics.
Halogen-free flame-retardant cables (such as UL3385 Tin Plated XLPE Insulated Wire, UL10588 Fire resistant wire, etc.) have several characteristics:
Flame retardant performance: It can delay the spread of flames and quickly form a dense carbonized layer during combustion, effectively isolating oxygen and heat . Under the specified test conditions, the spread of the flame is only within the limited range, and the residual flame or smoldering can extinguish itself within the limited time.
Environmental performance: Halogen-free, low corrosiveness of combustion products, and minimal harm to the environment and human body . Complies with environmental protection regulations such as RoHS.
Low smoke performance: The amount of smoke produced during combustion is small, and the visible distance is significantly increased, which buys precious time for passenger evacuation and rescue personnel to perform rescue operations , and does not affect escape and fire extinguishing . It also avoids suffocation caused by thick smoke and ensures personnel safety .
Mechanical properties: such as high tensile strength, high elongation at break , suitable for insulation or sheath materials of various cables and wires .
Heat resistance: It can withstand relatively high working temperatures and is suitable for various environmental conditions .
The difference between halogen-free flame-retardant cables and traditional flame-retardant cables
| feature | Halogen-free flame-retardant cable | Traditional flame retardant cable |
| Material composition | Excluding halogens, using polyolefin based materials | Containing halogens, usually made of PVC material |
| Combustion characteristics | Low smoke (light transmittance ≥ 60%), no toxic gases | Generate a large amount of smoke and toxic hydrogen halide gas |
| Environmental performance | Compliant with environmental regulations such as RoHS | Containing heavy metals and halogens, with poor environmental friendliness |
| Flame retardant performance | Flame retardant achieved through inorganic flame retardants | Flame retardant achieved through halogenated flame retardants |
| Application scenarios | Hospitals, shopping malls and other public places | General buildings and industrial sites |
