Birch Plywood is manufactured from birch veneers throughout, harvested from certified forests, normally bonded together with a phenol formaldehyde adhesive, which has superior resistance to loss of bond strength with time. Birch is a fine textured, strong, dense timber which is excellent for engineering applications where precision, stability, flatness and strength are primary considerations.
I wasn't quite satisfied with the plywood delivered. This birch was totally different to what I am accustomed ordering. The layers were coming apart easily and I had to use glue to reinforced certain sections that were coming apart.
