DYAS multiplex - All beech multi-layers plywood
is an all-beech plywood board made of many plies of rotary-cut beech veneers glued together with an adhesive. The grains of adjoining layers are at right angles to each other. Beech multiplex characteristic is derived from beech attributes such as great compactness, persistence, durability, flexibility, versatility etc. For beech multiplex, these properties are even enhanced owing to layering and gluing of many individual veneers.
DYAS Multiplex
is a health harmless plywood complying with the E-1 Class of formaldehyde escape according to ČSN EN 717-1. At customer´s request for even lower values of formaldehyde escape, we are able to offer variation, where material complies certification CARB phase II, according to ASTM D 6007-14.
Beech multiplex particularity is in the thickness of inner veneer plies, which are 2,2mm or 2,6mm thick. This subsequently influences the final multiplex properties. Owing to the bigger content of "massive" wood in the form of thicker inner veneers and less gluing, Multiplex characteristic is more li ke the one of solid beech wood.
Application:
For its excellent compactness properties, beech multiplex finds its use especially in mechanical engineering, building industry, automotive industry and transportation.
