General purpose plywood is of three or more veneered plies of birth wood glued together. There are two types of general purpose plywood available:
FSF grade plywood with improved resistance to humidity for both indoor and outdoor applications;
FK grade moisture resistant plywood for indoor application.
Such properties of plywood FSF can be accounted for by the use of high-quality veneer and phenol-formaldehyde resins for its production.
However plywood FSF is known by its constant emissions of formaldehyde. In view of high toxic effect of this substance, plywood FSF is not used for interior decoration and furniture production.
