Core Features

1. No corrosive hydrogen halide toxic gas generated during combustion. No acidic toxic gases such as hydrogen chloride or hydrogen bromide are released under high fire temperatures. It will not corrode communication equipment and connectors, greatly reducing the risk of personnel poisoning, and no highly carcinogenic dioxins will be produced.

2. Low smoke and low smoke density. It produces little smoke in case of fire, maintains visibility in the space and facilitates personnel evacuation. It is highly suitable for enclosed spaces (subways, computer rooms and buildings).

3. Flame retardant and self-extinguishing. The base material is mainly PE/EVA polyolefin, combined with inorganic flame retardants of aluminum hydroxide/magnesium hydroxide. It absorbs heat and releases water vapor when heated and decomposed, forming a carbonized isolation layer on the surface to inhibit flame spread. It meets the communication optical cable standards IEC 60332 and YD/T 1113.

4. Excellent mechanical and processing properties. It boasts outstanding tensile strength and elongation at break, good toughness and bending resistance. It can be directly extruded and shaped, adapting to the extrusion production of optical cable sheaths. It features aging resistance and weather resistance with stable performance at high and low temperatures. Some grades can be used in outdoor low-temperature environments of -40℃.

5. Superior electrical insulation performance. It has high insulation resistance and stable dielectric properties without interfering with optical signal transmission.
