Overview
HFDK-9253 is a long-life, unfilled, crosslinkable, low sag, low density polyethylene insulation compound designed for distribution and transmission power cable insulation applications. HFDK-9253 has been designed for cable production processes on horizontal vulcanization lines and for cables with thick insulation manufactured on standard catenary vulcanization lines. HFDK-9253 has a low level of additive bloom for a long storage life, low dusting and an enhanced degree of scorch retardance for long production run lengths during cable manufacture.

HFDK-9253 is recommended for the insulation of power distribution and transmission cables rated up to 69 kV
