Filler and floatability material - manufacturing process and tubular units that incorporate this material

摘要

This invention concerns a new filler and floatability material as well as its manufacturing process. For instance, this new material can be used as a filler and floatability material (A) which separates tubes or cables (1,2) in a tubular unit that includes an external sheath (B) surrounding a harness of tubes or cables (1,2). In view of its make-up this material also participates in the thermal insulation of said tubes. The invention concerns also such tubular units which incorporate the new material.
