Product introduction
SH8510-125 is a low smoke halogen-free flame retardant polyolefin insulating material with good electrical properties. It is mainly used for insulation of power cables, control cables, marine cables, etc. Its long-term service temperature is 125 ℃.
SH8510-125 products meet the requirements of GB/T 19666-2005, IEC60092 and other product standards, and meet the requirements of RoHS and REACH. It is a green environmental flame retardant material.
Product characteristics
·Excellent mechanical properties ·Low smoke emission and corrosiveness
·Excellent electrical performance ·Excellent Extrusion Processing Performance
Processing Guide
The best extrusion effect can be obtained by using 1:1.2 low compression ratio screw. PE/PVC screw extrusion can also be used.
Recommended processing temperature:
| position | 1area | 2area | 3area | 4area | 5area | nose | die port |
| temperature（℃） | 125 | 135 | 145 | 155 | 160 | 165 | 160-165 |
The melt temperature should be controlled between 165 and 175 degrees C, and the maximum should not exceed 180 degrees C.
If the material is stored in humid environment for a long time, drying treatment is recommended. The drying temperature is 80 C and the drying time is 1-2 hours.
Usually, the measurement of irradiation processing should be controlled at 8-15 Mrad, but ultimately the thermal extension should be taken as the criterion. The optimal control of thermal extension is 50-80%. If oil resistance is required, the thermal extension should be controlled at 20-30%.
Storage and Packaging
It should be stored in a dry and ventilated warehouse.
The products are packed in 25kg paper-plastic composite bags or 500kg container bags.
It can also be packed according to user's requirements.
