It is bonded with thermosetting, exterior quality phenolic resin adhesives commonly known as WBP. 2. 3. Idemat 1998 there is a possibility to use special lay-up schemes designed to improve mechanical properties which depend on the grain direction in the outer plies. The layer structure leads to more uniform properties than solid wood, since the effects of grain anisotropy are minimized. 076. 017. there is a possibility to use special lay-up schemes designed to improve mechanical properties which depend on the grain direction in the outer plies. The rigid laminated surface not only prevents moisture absorption but also ensures excellent abrasion resistance in aggressive conditions and smooth finish to concrete formwork. 078.

Valued for its appealing light color, Baltic birch plywood features a uniform grain, smooth texture and outstanding durability. The average transport distance to the Netherlands is 1600km by ship and 250km by trailer. The effects of manufacturing and service environ- ments on mechanical properties are discussed, and their effects on clear wood and material Birch, yellow. 8th International DAAAM Baltic Conference "INDUSTRIAL ENGINEERING" - 19-21 April 2012, Tallinn, Estonia . Finnish birch plywood is characterized by excellent strength and stiffness properties, and therefore it performs very well in applications demanding high strength and HANDBOOK OF FINNISH PLYWOOD TECHNICAL PROPERTIES OF FINNISH PLYWOOD Mechanical properties 3.
