Cable compounds use silanes in two ways: to crosslink the insulation and to couple mineral fillers in halogen-free flame-retardant (HFFR) compounds.
- Silane crosslinking: Manta V31 grafts to polyethylene with a peroxide initiator in the extruder. The grafted polymer is shaped into cable jacketing or pipe and then crosslinks with moisture.
- HFFR filler treatment: Manta A110 and Manta V31 treat ATH and MDH to improve filler dispersion.
- Melt flow: Manta L1631 enhances processability and reduces compound viscosity in HFFR cables.
