Low water absorption is a very important property, since most industrial insulation solutions are at risk of being exposed to water, high humidity or other liquids. Dry insulation always performs better than wet insulation. Water in the insulation material will dramatically decrease performance and add weight to the insulation, in addition to increasing the risk of generating a corrosive environment at the surface of the insulated equipment.
Corrosion is accelerated by the duration of any wetness, therefore protection against water trapped under or in the insulation material itself becomes a function of time. In other words:
Less water and faster dry-out = less corrosion
