Cross Link Compound:
1. Applications and cable specifications:
Used for 125°C less than 3KV locomotive cable, meeting GB/T 12528-2008. Suitable for environment with pollution of mineral oil and fuel oil.
2. Description:
Irradiation low smoke halogen free flame retardant POE compound for locomotive cable, based on special high oil resistant POE resin, is produced and pelletized by special technology, adding special modifier, halogen-free flame retardant, anti-oxidant, assistant crosslinker and other special additives.
3. Processing:
The compound can be processed with conventional extruders, and the normal PVC screw with a minimum 20:1 L/D. It is better if use low compression ratio screw.
The following temperature(°C) profile of extruder is recommended:
| Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
| temperature °C | 130 | 145 | 150 | 150 | 145 | 145 |
4. Storage and transport:
Packing: 25kg/bag, PE membrane inside bag and craft outside bag.
Avoiding in direct sunlight and weathering.
Storage place should be clean, cool, dry and ventilated.
5. Irradiated dosage:
The normal irradiated dosage(recommended) of irradiation cross-linkable low smoke halogen free flame retardant POE compound is 13 megarad.
