Description:
0835 cross-linkable semi-conductive shielding compound is used as strippable insulation shield for cross-linked polyethylene insulation power cable rated voltage up to 35KV. It's suitable for high temperature vulcanization processing method. 0835 provides excellence processability, fine surface smoothness, stable volume resistivity, low pre-cure or scorch characteristic, lower stripping force with anti-tearing property, leaving clean surface for insulation after stripped.

We suggest using double layer filter mesh with size 40 mesh (350μm).
We recommend hopper drying at 40~60'C for 4 hours to remove moisture before extrusion.
5.Storage:
Should be stored at room temperatures between 10~30°C. Recommended maximum storage period in dry and clean are is 12 months unopened and in original packaging after the manufacture.
