 low smoke halogen-free fire resistant polyolefin compound jacket material for mine cable
Standard: GB/T*********5, IEC*************9
1. The product not only has excellent low-smoke halogen-free flame retardant performance,but also has excellent extrusiion processing performance. It can be extruded on an ordinary PVC extruder. As long as the cooling device is normal, the extrusion processing speed can be accelerated. The performance of thid product is batter than similar products.

  The series are based on polyolefin and contain special halogen-free flame retardants and smoke suppresants,which are processed by precise mixing with special formulas. When the cable structure is desugned reasonably, it can pass the A/B/C type combustion test and meet the light transmittance requirments. When burning, no halogen acid gas is released, the amound of toxic and crossive gas is vey small and the smokeconcentration is very low. We can also provide anti-termite, anti-rodent and UV resistant properties according to customer requirment.

2.Feature ans uses
This product is suitable for accasions with high flame retardant requirments and low secondary hazards, such as subways, ships, high-rise building program-controlled switch rooms, computer rooms and various crowded public places. Suitabke for optical cable and wire core working termperature *0℃ low smoke halogen free flame retardant cable sheath. This product is guaranteed to pass verious beam burning tests and light transmittance tests. What's more, it has super cracking resistance property.

3. Extrusion process
The drying temperature is *5℃ and the drying time is at least 2 hours. It is advisable for the hot material to enter the extruder. It can be extruded by L/D ****5 extruder. When the screw compression ratio is low, the output volume is large. Ecah zone of the extruder must have a cooling control system and the indicated value of the temperaturecontrol table varis with the typr of extruder, each user should select a suitable temperature according to the specific conditions of the extruder used. The following temperatures can be used as a referancefor commissioning:
