An ideal density profile is essential in the production of quality wood based panels. Beside quality assurance, expensive overdimensioning can be avoided.
The laboratory density profile measuring system DENSE-LAB X determines the density distribution over the sample thickness (perpendicular to the panel surface) on small samples with the usual dimension of 50 x 50 mm². The measurement is non-destructive and non-contact using X-ray technology.
The density profile of wood-based panels is a key quality characteristic for panel manufacturers and laboratories (R&D). The density profile is related to nearly all panel properties and it is influenced by numerous properties of the material and even the conditions of the manufacturing process.
Typical density profiles are characterized by pronounced density maxima in the cover layers, a homogeneous region in the middle layer, and a smooth transition therebetween. In addition to such ordinary measurements on MDF, chipboard and OSB, most other wood-based materials such as plywood or LVL but also solid wood, sandwich panels and modern composites can be examined. Wood fibre insulating materials also have a pronounced density profile, which is important for their later use. For this special panel types with low densities, an adapted variant, a "light" version, was developed (DENSE-LAB X light).
