Polifoam
Polypropylene film foamed
POLIFOAM is a Polypropylene film foamed, mono-oriented, in tape form, developed for insulation, separation and filling of power, telecommunication and signal cables. It is a flexible film, very light in weight, with good mechanical and dielectric properties. POLIFOAM is available in three standard thicknesses of 100-125-175 microns. Because of the thickness of the film, rolls are relatively short in length, which makes spools the ideal put-up for this material.
