nonhygroscopic

In telecommunication, a filled cable is a cable that has a nonhygroscopic material, usually a gel called icky-pick, inside the jacket or sheath.

The nonhygroscopic material fills the spaces between the interior parts of the cable, preventing moisture from entering minor leaks in the sheath and migrating inside the cable.

It is a white, nonhygroscopic, crystalline powder that is practically insoluble in water, and freely soluble in chloroform, methanol and ethanol.

M4 flame fuel thickening compound is a nonhygroscopic thickener, adi-acid aluminum soap of isooctanoic acids derived from isooctyl alcohol or isooctyl aldehyd, which are obtained from the oxidization of petroleum.
