Description
This Anti-Cracking non-halogen, low smoke, highly flame retardant, low corrosive, low toxic, and thermoplastic compound is designed for general-purpose cable sheath applications. Used as sheath, it can pass the IEC60332-3, test for vertical flame spread of vertically mounted bunched wires or cables. Cable construction, of course, plays an important role in flame performance. It can be used as a sheath on cables operating at up to 90℃ with excellent fire safety characteristics and a good balance of properties. It is suitable for the power cable, especially big specification low-smoke nonhalogen flame-retardant power cable which lays down in the non-open-air situation.
Features
-Excellent Anti-Cracking characteristic
- Highly flame retardant
- Low smoke, low corrosion and low toxicity
- Ease of extrusion and no special screw required
- Environmentally friendly (lead free, halogen-free, sulfur/antimony-free)
- UV resistant

It can be processed on a wide range of commercially available cable fabrication equipment and screw types. A single flight PE metering screw with feed, transition and metering sections is recommended for most applications. Adequate output and torque limits are key determining factors for screw selection. A very low compression (1.2:1 type) screw can be used successfully if a breaker plate and 40/60 mesh screen pack are used to generate backpressure. Based on tests completed on 90mm, 25:1 standard extruder, the following typical conditions are recommended as a starting point. However, it may be necessary to optimize conditions for a given set of construction, extruder-screw configuration and tooling.
