Abstract (en)
A filler for a telecommunication cable (1) comprising a foamed petrolatum (4) or petroleum jelly is disclosed. The cell structure is closed-cell and provides a light-weight cable filler with good electrical insulation properties, particularly a low dielectric constant. The foam exhibits a cup weight of about 60 to 135 gm/200 mls. The foamed petrolatum may be stabilized with a polymeric stabilizer to ensure integrity of the foam.
