12mm WBP Chinese Plywood 2440x1220mm - 8'x4' Panel - General Description :
Economy-Grade Imported Hardwood Ply

The plywood surface veneers are of Okoume or similar red hardwood; the plywood core veneers are a species of poplar.
The board is normally manufactured with an odd number of plies, each ply being oriented at 90 degrees to the adjacent one, to create a balanced construction. The plywood face and reverse veneers run in the direction of the length of the sheet : long-grain plywood.


Thickness tolerances of plywood - differences are allowed from the nominal thickness of the board after sanding.
In the case of 12mm plywood, this is from 11.2mm to 12.3mm, as a mean thickness.
Length and width dimensions of the plywood are stated within +/- 1mm tolerance from the mean dimensions, to allow for the sanding process.


Adhesives used in the plywood manufacture are Phenol (WBP type) for the core veneers, and Melamine Formaldehyde (Type 1 Exterior) for the face veneers.

Plywood face grading is stated as B/BB but it isn't unknown for it to turn up as a "C" marking;
- a B plywood face is described as a neatly cut veneer, substantially defect free and sanded smooth;
- a BB plywood face allows minor defects, so long as they are filled and sanded.
- C plywood face would be larger defects, filled and sanded with possible "missed" fillings.
These plywood face-grade descriptions are summarised from BS6566 - (which although not a current standard, has been adopted as a description by several Plywood Mills.)
Long-grain hardwood veneered plywood - many boards have a decorative veneer but would have to be selected if required for this use;


Weight per 8x4 x 1/2" plywood board is approximately 19Kg;

Moisture content of the plywood is approximately 10%;

Plywood Strength Data - non declared, not CE marked for structural use.

Applications - Furniture, Shopfitting, Exhibition Stands and general construction work. This board has an external glueline WBP (Water & Boil-Proof); WBP bonded plywood generally has a high resistance to humid and wet environments, although the forces of expansion in a saturated timber veneer may cause the veneer to actually split, while the glueline itself is sound - This does not indicate that the plywood has been manufactured incorrectly - timber is a natural material subject to swelling when it absorbs moisture. Be aware that Poplar does not posses a high resistance to fungal decay in humid conditions. For long service in these conditions, design consi­dera­tions and the appropriate weather-proof finish of the plywood are of the highest importance. The timber (especially end-grain) would need to be coated and maintained to a BS-CP external specification for any external use. These plywood boards have not been CE grade tested for structural uses such as floor decking, roof decking or wall sheathing - (although they are of comparable quality to ones that are CE marked.) We would be able to supply a CE marked plywood, but this would be at a higher price.

This ply is more stable and generally will swell, twist or warp less than a softwood core plywood.
