The Density of Plywood is higher than the density of the timber species used to manufacture the products .
The face/back veneers of plywood weight practically much less than the core veneers. So the density of plywood is mainly depended on the timer species of the core veneers .
Usually 4 kinds of timber species are used to manufacture the cores of plywood ( film faced plywood ) , i.e. birch, hardwood, pine and poplar. The density of different plywood is listed as follows:
Sometimes, buyers order combi core plywood , such as combined poplar/hardwood, combined birch/poplar and so on . The density of combi plywood is depended on the components of core .
