Description
ZARPLSTM LLB8706 is a black linear low density compound for jacketing of power and communication cables. Characterized by:
- High melting temperature (approximately 120ºC)
- Low coefficient of friction
- Good abrasion resistance
- Good petroleum-jelly resistance
- Low water permeability
- Very wide processing window
ZARPLSTM LLB8706 contains 2.5% well-dispersed carbon black in order to ensure excellent weathering resistance
Applications
ZARPLSTM LLB8706 is intended for jacketing of power and communication cables. The abrasion resistance combined with low coefficient of friction makes it ideally suitable for jacketing of fibre optic cables.

Processing Guidelines
ZARPLSTM LLB8706 provides excellent surface finish and allows a broad processing window. Standard PE-screw gives satisfactory results but also low compression screws can be used successfully. We suggest a temperature profile as below:
- Feed section: 170ºC
- Metering section: 200ºC
- Head and die 210º C
If preheating and/or drying is used, the maximum temperature should be 90ºC.
Packaging
