Neoprene’s Excellent Moisture Resistance

Neoprene is a popular choice of material for use in marine applications due to its excellent water-resistance properties. While neoprene is not a 100% waterproof material, it does offer a high level of moisture-resistance and will not be harmed by moisture if left on its surface. There are two types of neoprene available, solid and foam, that both offer excellent moisture-resistance properties.

Solid neoprene is a dense and non-porous material that is highly resistant to moisture. Although it is a water-resistant material, if moisture is left unattended for extended periods of time, it will eventually seep through the material. Closed cell foam is also a highly moisture-resistant material with an absorption rate of less than 5%; however, like solid neoprene, moisture should be wiped away quickly to avoid permeation.

Both solid and foam neoprene are used for a number of marine applications including boat bumpers, seals and gaskets, and electrical insulators. Solid neoprene is ideal for industrial seals and gaskets that are used to prevent leakage of oils and other moisture due to their dense structure. On the other hand, closed cell foam is better used as protective insulators because they are more pliable than solid neoprene.
