How Moisture Affects Phenolic Cotton Sheet Performance

Moisture significantly impacts the performance of phenolic cotton sheets, a crucial insulating material in various industries. When exposed to moisture, these sheets can experience dimensional changes, reduced electrical insulation properties, and potential degradation of mechanical strength. The hydrophilic nature of cotton fibers allows them to absorb moisture, which can lead to swelling and alterations in the sheet's structure. This moisture absorption can compromise the electrical resistivity of the material, potentially affecting its insulating capabilities. Additionally, prolonged exposure to moisture may weaken the bonding between the phenolic resin and cotton fibers, potentially leading to delamination or reduced overall durability. Understanding these effects is essential for maintaining optimal performance and longevity of phenolic cotton sheets in diverse applications.
