Polyolefin:
1. Applications and cable specifications of Polyolefin:
Common insulation for flame retardant wires and cables.
2. Description of Polyolefin:
Thermoplastic, low-smoke, halogen-free and flame retardant POE insulating compound, based on POE resin, is produced and pelletized by special technology with adding special modifier, flame retardant, anti-oxidant and other special additives.
3. Processing of Polyolefin:
The compound can be processed with conventional extruders, and the screw with a minimum 20:1 L/D and a compression ratio of 1.2 is recommended.
The following temperature(°C) profile of extruder is recommended:
| Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
| temperature degree C | 140 | 145 | 150 | 150 | 145 | 145 |
Note:Compound should be dried at 70-80°Cbefore use, which has storage time exceeding two months.
4. Storage and transport of Polyolefin:
Packing: 25kg/bag, PE membrane inside bag and craft outside bag
Avoiding in direct sunlight and weathering
Storage place should be in clean, cool, dry and ventilated conditions
