Processing :
The product should be dried before use. It is better to use the rate ≤(1.5-2.0):1 low compression ratio screw to extrude. Recommended extrusion temperature:different varieties, different machine types processing temperature is different, please adjust according to the plasticization of the material, contact the supplier if necessary)
The following temperature(℃) profile of extruder is recommended
| Type | Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | Head | Die |
|---|---|---|---|---|---|---|---|---|
| EBXL- 618 | Temp(℃） | 110 | 150 | 170 | 180 | 185 | 185 | 185 |
Note: The material should be used after drying. The drying temperature is 40-60°C, Time is 2-3h. It is strictly forbidden to dry for too long
Irradiation dose
About 8-14 megarads, thermal elongation should be 40-60%
Storage and transportation
Packing: 25 / 30 Kg packed in Moisture Barrier Multi-layer liner with PP Woven bag.
Transportation and storage: Cable materials should not be exposed to the sun and rain during transportation. They should be stored in a clean, cool, dry and ventilated warehouse.
