LSZH compound:
1. Applications and cable specifications of LSZH compound:
Common jacket for flame retardant wires and cables which operation temperature is at 90 degree C.
2. Description of LSZH compound:
Thermoplastic, low-smoke, halogen-free and flame retardant POE jacket 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 LSZH compound:
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 degree C before use, which has been stored more than two months.
4. Storage and transport of LSZH compound:
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.
