about the extruder
Silane XLPE Cable Compounds
The silane crosslinked cable compounds (also known as sioplas or PEX-B) are now widely used in the wire and cable industry as an insulating material for low-voltage power cables (≤ 10KV). It is a two-step reactive extrusion process. Here we introduce the first step, injecting a silane-peroxide mixture into the melted polyethylene to get a grafted polyethylene. Achieving a high grafting rate depends on the highly distributed dispersion of the compounding system, precise temperature control, and residence time of the material in the extruder.
