Panel consisting of an odd number of perpendicularly overlapping wood veneers and bonded together by synthetic resins, under the action of pressure at high temperature, which make a product having high stability, mechanical strength, tensile strength and a low level of cracking and warping.
It is subject to various kinds of coatings such as wood veneers or thin (hpl) laminates.
Depending on how the veneer is removed from the trunk, the plywood can have two configurations: peeled plywood and sliced plywood (listed or cutting plane, commercially designated as decorative plywood).
Beyond these, we can consider a third type of plywood that besides the type of veneer, have certain technical attributes, depending on the purpose it was intended (anti-slip, formwork, maritime, etc):
Anti-slip plywood – panel obtained by bonding superposed layers with crossed wires, usually at right angles, integrally in poplar, coated with phenolic film of 120 g/m² with a non-slip face for use in humid environments or in the exterior;
Formwork plywood - panel obtained by bonding adjacent layers of crossed wires, usually at right angles for outdoor use, having faces in peeled veneer and coated with phenolic film of 120 g/m²;
Maritime plywood - panel consisting of wood veneers with faces and core with its own durability characteristics for applications in contact with sea water, perpendicularly superimposed and with a bonding quality suitable for that effect.
