Birch plywood of grade FSF State Standard 3916.1-96
General information. Birch plywood of general-purpose with exterior layers of hardwood veneer has high physical-mechanical properties of birch in combination with multilayer structure, which ensures the exceptional strength of plywood. This property is highly valued in many productions where strength of material is of the utmost importance.

This material also has such important properties as warm tone colors and beautiful texture of birch plywood, which together with excellent quality of surface is decisive for the choice of this material for production of furniture, for interior and exterior decoration.
The plywood of grade FSF have of high water resistance and strength.

Sort of plywood is designated by the combination of veneer sorts of the front and reverse layers: (sort of front layer / sort of reverse layer), for example, I/I, I/II, II/II, II/III, II/IV, III/III, III/IV, IV/IV
Produced sorts: I/II; II/II; II/III; II/IV; III/IV; IV/IV

Sizes of birch plywood of grade FSF: 1525х1525 mm, 1475х1525 mm, 1425х1525  mm

Thickness of sheets: 4; 6; 8; 9; 10; 12; 15; 18; 21 mm.

Glue - on the basis of phenol-formaldehyde resin of grade SFZh-3013
Ultimate strength by splitting along the glue film of the plywood after boiling in water for 1 hour – 1.5 MPa  
Content of free formaldehyde conforms to the international emission class E-1

Application. High strength and high performance qualities ensure the broad use of the plywood as a finishing material, in machine building, construction, production of furniture and tare, and in other branches of industry.
Increased water resistance of the plywood of grade FSF enables its use for internal and external applications – in shipbuilding for interior structures, as a basis by assembly of flexible roofing for arrangement of sheathing on sloped roofs, for smoothing of floors under parquet, as well for fabrication of exterior structures which will be finished, etc.
