DYAS beech - Plywood for general use
is an all-beech plywood made of many plies of rotary-cut beech veneers glued together with an urea-formaldehyde adhesive. The grains of adjoining layers are at right angles to each other. For its excellent characteristics such as great compactness, persistence, flexibility and size stableness, beech plywood is an important material in furniture-making production and joinery, for the production of casings, wooden toys and musical instruments.
DYAS beech
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.
