Laminated plywood is a plywood whose whole surface is covered by the moisture-resistant layer of laminate. A paper-resin coating impregnated with phenol-formaldehyde resins is used as a laminate. This is one of the most water-resistant boards: when used as a formwork, it can withstand up to 50-100 working cycles (rotations). As for lamination, we use birch plywood FSF. The birch one because birch veneer is on average 20% stronger than the pine and spruce veneer; FSF (plywood of increased moisture resistance) - because laminated plywood is often used as a formplate.
FANERA BAZAR company is one of the largest Eastern European plywood manufacturers that supplies any volume of laminated moisture-resistant plywood in wholesale and at retail. In stock on any day there is always a large-format plywood of all standard sizes.
Almost always, the role of laminate is played by dense paper impregnated with phenol-formaldehyde resins. These resins are not mixes with water and do not dissolve in it, and after heating and subsequent cooling, they acquire a glassy consistency. After impregnation with phenol-formaldehyde resins, the paper acquires the hardness and density of plastic. Laminate is spliced to the FSF plywood by the same resins. The lamination itself is carried out in a press under the high pressure and temperature.Under these conditions, resin is getting softer and splices the outer layer of the veneer and a laminate layer together. After what the material is cooled, and its ends are covered by the special moisture-resistant paint to prevent the edges of the sheet from drying out.
As a result, we get a building material with a protective layer that prevents ingress of the moisture into the leaf. The sheet preserves its properties as long as the layer of the laminate on it is whole. If the film will be damaged, water will ingress under it, and the veneer will begin to swell.
