Hydrophobicity

Hydrophobicity — the ability of the material not to be wetted with water.

Hydrophobic substances are many metals and organic compounds.

Hydrophobic substances serve to protect products from destructive effects.

Hydrophobicity (from ancient Greek ὕδωρ — water and φόβος — fear, dread) is a physical property of a molecule that «seeks» to avoid contact with water[1]. The molecule itself is called hydrophobic in this case.

Hydrophobic molecules are usually non-polar and «prefer» to be among other neutral molecules and non-polar solvents. When in water such molecules often cluster with the formation of micelles. Water on hydrophobic surfaces is collected in droplets with low wetting angle values.

Today, the most effective technical solution to improve the reliability of external insulation in conditions of intense pollution is the use of polymer insulators with a protective shell of silicone mixture.

Many years of operational experience established that silicone hydrophobicity can persist for many years without any signs of the service life limiting due to the fact that polymers with low molecular weight and weak binding energy, but providing hydrophobicity, can diffuse from the shell depth to its surface. Thus, the hydrophobic properties of insulator protective shell are transformed into the deposited layer of contamination, that prevents contamination accumulation.

Hydrophobicity of our products protective shell.
