Lightweight particle board, made of poplar timber

poplar particleboard

Lightweight particle boardLightweight particle board poplar panels are unique both in their appearance and in their physical and mechanical properties. They have a compact core of environmentally-friendly poplar timber, and a fine surface with micro-particles with very light color, typical of the wood they are 100% made of.

The careful selection of poplar timber particles, mostly coming from trees discarded by sawmills and plywood producers, ensures excellent stability and high workability even at the edges, as well as ease of cutting, machining, milling, and molding processes. The inner layer is very compact and homogeneous and, thanks to peculiar poplar features, it allows long life to processing tools, as well as excellent screw-holding ability.

Lightness comes from raw material selection and a special production process: it simplifies handling and following manufacturing processes, and helps save shipping costs of finished products. Lightweight particle board poplar panels density goes down to 450/490 kg/m3 (compared to 550/650 kg/m3 of other kind of particle boards)!

Panels are suitable for finishing with melamine-impregnated papers, or coating with plastic laminates, finish foils, floors overlay, PVC, PP and veneers.

The standard dimensions most commonly produced are:
4220 x 1860 mm
4220 x 2070 mm
3760 x 1860 mm
3760 x 2070 mm
2800 x 2070 mm
Thickness ranges from 8 to 58 mm

Special sizes or thicknesses can be produced upon quotation and minimum quantity requirements.

Panels are available raw, melamine faced and veneered. Standard range or custom possibilities, upon request.

Bonding is made with certified urea-formaldehyde resin, suitable for panel use in dry conditions. The panel is compliant with Class 1, according to the requirements of EN 717-1 (single-value <= 8mgHCHO/100g – medium value <= 6.5 mgHCHO/100g) methodological standards EN 120, commercially known as E1.
Upon request, they also meets the requirements of the CARB 2 California Code of Regulation (FRO ATCM §93210.2 (a) Table 1, Phase 2) and TSCA Title VI – 40 CFR Part 770.

Triple-core poplar blockboard: bending strength and lightness

triple core poplar + HDF

triple core poplar blockboardWhen producing large-size sliding doors, dividers and partitioning, tables and bench tops, the risk of warping or bowing is very high.
The so-far unequalled solid wood solution, is triple-core poplar blockboard.
Triple-core blockboard is a special construction with 3-ply of cross-banded blockboard cores, overlaid by poplar veneer or thin HDF.
In comparison to any other kind of wood-based panel, this blockboard, available in the thicknesses between 36 mm and 60 mm, has superior bending strength, the lightness of Italian poplar timber (between 400 and 450 Kg/m3) and high screw-hold ability.

Trade names
Triplecore blockboard, Ecocore, lumber triple core plywood, triple core poplar board, cross-core poplar panel, 5‑ply Poplar Blockboard Panel, Pappeltischlerplatte, Staptischlerplatte, Stabpappelsperrholz, Stabilomassief, panneaux latté peuplier, alistonado de chopo, listellare pioppo tripla anima.

Construction
The triple-core poplar blockboard composition is a 5-ply construction. For example in 50 mm:
– about 2 mm poplar veneer cross grain (B)
– about 16 mm blockboard poplar core long grain (A)
– about 14 mm blockboard poplar core short grain (A)
– about 16 mm blockboard poplar core long grain (A)
– about 2 mm poplar veneer cross grain (B)

triple core blockboard

The poplar face is ideal for veneering. When the board is intended to be painted or laminated, the outer veneer is replaced by a 3 mm thin panel of HDF (high density fiberboard). This panel is called triple-core poplar blockboard + HDF.

And for very special paintings applications, to reduce the consumption (and costs) of paint, the triple-core poplar blockboard + HDF is also available overlaid with a 240 gr/m2 lacquering paper.

Triple core blockboardUsing this product, veneered, laminated or lacquered, the leading Italian designer Mauro Lipparini and furniture manufacturer Misuraemme brought a real innovation in the concept of bookcases with the Crossing product line, a versatile modular system of panels to create wall shelving: the thickness (38 mm) and the bending strength and lightness of poplar blockboard, give the system a stability that allows you to hang the shelf directly on the wall with brackets, creating an unusual “visible lightness“.

Bonding of the faces is made with urea-formaldehyde glue (UF) (formerly called IF20), while the lumber core is bonded with PVAc (D3), in compliance with the provisions of the EN 314 standard.
After suitable treatment in view of resistance to humidity, the board complies to Class 1 requirements for the use of boards in dry environments (EN 636-1).
Class 2 (formerly called AW100 or MR) can also be produced upon request.
Formaldehyde emissions are below those established for Class E1 in conformity with the EN 636 standard. The low-emission class E1 panels do not cause a concentration of equilibrium in the air of the test chamber (defined in the EN 717-1 standard) greater than 0.1 ppm, the limit established by the World Health Organization for living and residential environments.

Block-board, the solid lumber core panel

3-ply spruce blockboard

3plyspruceblockboardBlock-board (also called lumber core) is a timber material consisting of a core of wooden strips placed between two layers of veneers (3-ply in all), with extraordinary characteristics of bending strength, lightness and screw-hold ability. As it’s a real solid-wood alternative to timber, suitable for the production of high-quality and long-lasting furniture, furnishings, partition walls and cabinet-making.

Composition
A. The center of the panel (block-board core) is a solid slab generally made with side-glued lumber strips in the width of 28-38 mm; the most common kiln-dried soft wood timber species used in the cores are poplar, spruce and pine.
B. The block board core (long-grain) is then glued under high pressure with one layer of crossband veneer sheet on each side. The veneer used is normally poplar or Ceiba pentandra (exotic veneer from timber plantation wood, also called fromager or fuma), with a minimum thickness of about 2 mm per side.

3 ply blockboard draw

While most block-board manufacturers are producing the 3-ply construction, in Italy the special 5-ply blockboard has been developed.
