Abstract
Petrolatum-based filling compounds are known to migrate into the insulation and jacket of telephone cables and to extract the stabilizers, and as a consequence, to affect the physical and/or electrical characteristics of those cable components. It does not seem possible to avoid these characteristics of petrolatum in commercial compounding operations. The filling compound of this specification is for use in telephone cables and is based on better resistance to dripping at elevated temperatures, compatibility with high density polyethylene insulation and low density and medium density polyethylene jacket compounds. It has processability at moderate elevated temperatures, resistance to cracking at room temperature and low temperatures, adhesiveness and desirable electric properties.
