ABSTRACT:
The invention relates to a sealed cable article and method for sealing the area between two or more cables and between the cables and an enclosure with a shaped article at a location where the cables exit from the enclosure, the method comprising (a) providing a shaped article of a polymeric gel said gel having (i) a cone penetration value of about 30 to about 450 (10.sup.-1 mm), and (ii) an elongation of from about 25% to about 750%; (b) positioning the shaped article around the cables; and (c) positioning the enclosure such that it surrounds the shaped article. An article aspect of the invention comprises two or more cables, an enclosure surrounding the cables, and a polymeric gel having the properties as described above sealing the area between the cables and the enclosure. This invention also relates to a sealed cable end article and a method of sealing the end of a cable, the method comprising positioning a shaped article of a polymeric gel having the properties as described above to cover the end of a cable and positioning an enclosure around said shaped article and adjacent region of the cable. The article comprises one or more cable ends with a portion of the cable end exposed, a shaped article of a polymeric gel having the properties as described above positioned at the cable end, and an enclosure which surrounds the shaped article and the adjacent region of the cable.
