What makes marine plywood different from BWR and PF waterproof plywood?
Marine plywood is quite a different concept. To make Marine ply, veneers of few selected species are only used. Marine ply will never be made of any given species. The few selected species include Eucalyptus, Gurjan and Popular. At time a combination of these veneer species i.e. say eucalyptus and popular or eucalyptus and Gurjan is used to make marine plywood.
Also the use of undiluted or concentrated phenolic resins like phenol formaldehyde increases waterproofing quality of Marine plywood significantly. Whereas for BWR grade waterproof plywood and PF grade plywood, the adhesives are diluted before using it to glue veneers together. For home furniture necessities using waterproof BWR grade waterproof plywood is usually considered to be good enough. The costlier Marine grade plywood is usually avoided for home interior purpose for such a purpose.
