Microcrystalline Cellulose

In melamine resin systems used for laminate flooring, MCC fibers perform several important functions. They increase the viscosity of the resin, thereby stabilizing the entire resin system. This allows for higher resin application weights without the resin flowing uncontrollably during the pressing process.

Another key advantage is the improved distribution of corundum particles within the melamine layer. Corundum is responsible for the abrasion resistance of laminate surfaces. A more homogeneous particle distribution results in a uniformly durable surface and facilitates achieving high abrasion classes in accordance with EN 13329. 

Furthermore, the use of MCC enables the application of liquid overlays. Compared to conventional overlay papers, this approach reduces both material and processing costs while maintaining excellent surface quality.

In addition to fibrous MCC, spherical MCC Spheres provide further functional benefits for the top layer of laminate flooring. 

The spheres act as microscopic spacers between the corundum particles, improving their uniform distribution throughout the coating. As a result, the finished laminate surface exhibits significantly higher abrasion resistance. In the Taber Abrasion Test (ISO 24338), the surface withstands a substantially higher number of revolutions. 

Another major advantage becomes evident during production. Unlike hard mineral fillers or glass beads, MCC Spheres have a considerably lower specific hardness. This reduces wear on press plates, extends their service life, and lowers maintenance and tooling costs. 

MCC Spheres also offer excellent optical performance. Thanks to their refractive index, which closely matches that of melamine resin, they remain virtually invisible within the cured coating. As a result, the decorative appearance of the laminate surface remains completely unaffected.
