EPchem® RRU-0706 is polyolefin based material containing inorganic flame retardant, antioxidant, lubricant, etc., produced by mixing, plasticizing and then pelletizing. RRU-0706 is appropriate for sheath of remote cables and so on.
RRU-0706 is excellent in mechanical properties, outstanding resistance to UV and good processability.

Processing
RRU-0706 has good processing performance, can be well processed using PVC and Polyethylene standard extrusion screw, preferring a low compression ratio (1.2 ~ 1.8) screw for the best extrusion effect. In general we recommend the following processing conditions:
- Extruder L/D: 20~25
- Filter (mesh): 30~60
- Temperature setting:
   110ºC  120ºC  135ºC 145ºC  150ºC  150~165ºC
The above temperatures are for reference only, but should be adjusted depending on specific equipment.
RRU-0706 can be extruded by squeeze die but also squeeze tube die.
Storage
These compounds must be stored under the following conditions:
- closed and undamaged bags
- ambient temperature does not exceed 45ºC
- avoid direct exposure to sunlight and weathering
- shelf life:12 months.
To be packed in aluminum foil bag inside and kraft paper bags outside, 25kg net each; or damp-proof cabinets on pallet, 1000kg net each.
