Advantages of low smoke halogen-free cables

Low smoke halogen-free cableEnvironmentally friendly cables made from rubber materials that do not contain halogens (F, Cl, Br, I, At), lead, cadmium, chromium, mercury, or other environmental substances, and do not emit toxic smoke (such as hydrogen halides, carbon monoxide, carbon dioxide, etc.) when burned.
The halogen pointer is: all halogen values ≤ 50PPM (according to regulation PREN 14582)
The content of hydrogen halide gas produced after combustion is less than 100PPM (according to regulation EN5067-2-1)
The pH value of the hydrogen halide gas produced after combustion dissolved in water is ≥ 4.3 (weakly acidic) (according to regulation EN-50267-2-2)
After burning in a closed container, the product passes through a beam of light with a transmittance of ≥ 60% (according to regulation EN-50268-2)
Pb<90PPM, Cd, Cr6+, Hg, PBBs, and PBDEs are all less than 5PPM
Purpose:
[1] This product has excellent flame retardant performance, with minimal smoke during combustion and no corrosive gases escaping. It is widely used in nuclear power plants, subway stations, switches and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, oil platforms, as well as places with concentrated personnel and low air density.

low smokeHalogen-free wireCharacteristics: Low smoke halogen-free cable
(1) The tensile strength is greater than that of general PVC wires: the tensile strength of general PVC wires is greater than 1.05Kgf/mm2, while the tensile strength of low smoke halogen-free wires is greater than 1.2Kgf/mm2;
(2) Has good weather resistance (-30 ℃~105 ℃);
(3) Has good softness (hardness of 80-90);
(4) Has non migratory properties (as no plasticizers are added to the formula of this product, there will be no migratory properties);
(5) No toxic black smoke will be produced during combustion (a small amount of white smoke will be produced);
(6) Has high volume resistivity: PVC wires generally have a resistivity of 1012~1015 Ω/cm3, while low smoke halogen-free wires have a resistivity greater than 1016 Ω/cm3;
(7) Has good high voltage resistance characteristics: PVC wires generally withstand 10KV or more, while low smoke halogen-free wires can withstand up to 15KV or more;
(8) Has good elasticity and viscosity. 3 Low smoke halogen-free wire formula additive materials: (1) Linear PE and elastic PE are selected as the main resins, and three types of metal oxides containing crystal water are used as flame retardant materials: they lose crystal water at 200 ℃, 300 ℃, and above 300 ℃, respectively.
