Why is Some Moisture Resistant MDF Colored Green?

Manufacturers of Medium Density Fiberboard (MDF) produce a diverse range of MDF sheet products tailored to meet the specific needs of various customer segments. Among the largest consumers of MDF sheet material are industries involved in building and construction. In this sector, differentiation between various grades of MDF sheets is crucial, especially when on-site.

To facilitate easy identification, manufacturers have incorporated a green dye into moisture resistant MDF sheets. This distinct coloring serves as a visual marker, aiding building and construction trades in swift recognition of moisture resistant variants. Notably, the prevalent sizes in use—such as 8" x 4" and 10" x 4" MDF sheets—often exhibit a green hue or possess a green core, predominantly representing moisture resistant MDF.

It's important to note that the green dye added to moisture resistant MDF serves solely for identification purposes and does not contribute to its moisture-resisting properties. The resilience against moisture arises from the specific resin employed in bonding the wood fibers during the manufacturing process of these MDF sheets, a composition distinct from that utilized in standard-grade MDF.
