The resistance to indentation is a function of both the wear layer's hardness and the structural density of the underlying HDF core. While the melamine wear layer provides surface durability, the core provides the 'cushion' and mass that resists permanent deformation. A higher density core, when matched with a dense wear layer, minimizes the likelihood of deep indentations occurring when items are dropped or when heavy, steady loads are placed on the surface, ensuring the flooring remains level and aesthetically sound.

How does wear layer density affect surface resistance to indentations?
Wear layer density, often correlated with the product's AC rating, is a primary factor in indentation resistance. A denser wear layer, combined with a high-density core, provides better support against concentrated pressure, helping the floor resist dents from heavy, dropped objects.
