Water absorption

Water absorption is an important factor to consider when choosing materials. Materials intended to be used in humid environments, such as shipbuilding, construction or the manufacture of packaging, must be able to absorb a certain amount of water without losing their mechanical properties.

The water absorption of materials can be affected by various factors such as temperature, humidity, salt concentration and pH. In some cases, water absorption can also lead to chemical reactions that can affect the structure of the material.

Materials such as wood, paper and textiles are particularly susceptible to water absorption because they are porous and can absorb water into their structure. This can lead to a weakening of the material and a change in its dimensions.
