Why Do Furniture Edging Strips Turn White?53

As a leading manufacturer of furniture edging strips in China, we have encountered numerous cases where customers have complained about the occurrence of white edges on their products. This issue, commonly known as edge whitening, can significantly impact the aesthetics and durability of furniture, leading to dissatisfaction among consumers.

Edge whitening is a phenomenon that occurs when the thin layer of melamine or PVC material used to cover the edges of furniture panels becomes exposed to moisture or heat. This can happen during the manufacturing process, storage, or even during normal use. When the protective layer is compromised, the underlying substrate, which is typically made of wood or particleboard, absorbs moisture and expands. This expansion causes the melamine or PVC layer to stretch and become loose, resulting in a visible white edge.

Several factors can contribute to edge whitening, including:
Excessive moisture: Exposure to high humidity or direct contact with water can cause the substrate to absorb moisture and expand, leading to edge whitening.
Heat: High temperatures, such as those encountered during hot summer months or near heat sources, can soften the adhesive that holds the edging strip in place, causing it to loosen and turn white.
Poor adhesion: If the adhesive used to bond the edging strip to the substrate is weak or insufficient, it may not be able to withstand the expansion and contraction of the substrate, leading to edge whitening.
Improper storage: Furniture panels should be stored in a dry, well-ventilated area to prevent moisture absorption and edge whitening.

To prevent edge whitening, manufacturers and end-users should take the following precautions:
Use high-quality edging materials: Opt for edging strips made from durable and moisture-resistant materials such as PVC or high-pressure laminate (HPL).
Ensure proper adhesive application: Use a strong and flexible adhesive that is compatible with both the edging material and the substrate.
Control moisture: Store furniture panels in a dry and well-ventilated area to prevent moisture absorption.
Limit heat exposure: Avoid placing furniture near heat sources or in direct sunlight.
Clean gently: Use a soft, damp cloth to clean furniture surfaces. Avoid using abrasive cleaners or excessive force, as this can damage the edging strip.

In some cases, edge whitening can be repaired by applying a thin layer of clear nail polish or furniture touch-up paint to the affected area. However, it is important to note that this is only a temporary solution and does not address the underlying cause of the problem. To prevent recurring edge whitening, it is essential to identify and address the underlying factors contributing to the issue.
