Why Does White Edge Banding Turn Black?75

As a leading manufacturer of edge banding in China, we have encountered various inquiries regarding the discoloration of white edge banding. In this comprehensive guide, we will delve into the underlying causes of this phenomenon and provide practical solutions to prevent it.

Causes of White Edge Banding Turning Black

The primary reason behind white edge banding turning black is the presence of iron particles. Iron is a common impurity found in raw materials used for producing edge banding, such as PVC and ABS. These iron particles can react with oxygen and moisture in the air or within the adhesive used to bond the edge banding, leading to oxidation and subsequent darkening.

Several factors contribute to the oxidation process, including:
High humidity: Moisture accelerates the oxidation process, making white edge banding more susceptible to blackening in humid environments.
Direct sunlight: UV rays can break down the polymers in white edge banding, making them more vulnerable to oxidation.
Improper adhesive selection: Using incompatible adhesives that contain corrosive substances can promote oxidation and discolor the edge banding.

Prevention and Solutions

To prevent white edge banding from turning black, several measures can be taken:
Use high-quality materials: Opt for edge banding manufactured from pure原材料 without iron impurities.
Control humidity: Maintain a low humidity level in the production and storage areas.
Protect from sunlight: Store and transport the edge banding in UV-resistant packaging.
Select compatible adhesives: Use adhesives specifically designed for edge banding applications that do not contain corrosive agents.
Apply a protective layer: After applying the edge banding, consider using a protective coating or sealant to create a barrier against moisture and UV radiation.

Additional Tips
Inspect the raw materials and finished products regularly for signs of discoloration.
Educate customers about the proper handling and storage of edge banding to minimize exposure to moisture and sunlight.
Stay updated on the latest technological advancements in edge banding production to mitigate the risk of discoloration.

By adhering to these recommendations, you can effectively prevent white edge banding from turning black, ensuring optimal aesthetics and longevity of your furniture products.
