Poplar wood is versatile, easy to work with and light. It is clear and homogeneous in appearance. Its uses are very diverse, they are even expanding in the industrial and structural scope, and their maximum use.
Poplar, also known as poplar, is a typical species of wetlands in the northern hemisphere. However, due to the interest in its use, it is easy to find it in any other part of the world that meets the humidity requirements necessary for its growth. China, the largest producer of poplar wood, stands out in this regard.
It is also a tree of rapid growth which is often used for reforestation near rivers and basins. What on the other hand facilitates its commercial exploitation and makes it a tool of high ecological value.
Types of poplar: there are different species of poplars or poplars. This includes black poplar (Populus nigra), white poplar (Populus alba) and poplar (Populus tremula)
These different types of poplars show slight variations in their properties or characteristics. White is lighter, European is also light, but slightly denser, and black is the lightest of all and nodes are more common.
In this article we will emphasize the qualities of European poplar, the most common in our country.
Characteristics of poplar wood
Color: Light brown heartwood and light yellow sapwood. Differentiation is not always obvious.
Fiber: In a straight line.
Density: Light wood, with a density of approx. 450 kg / m3 at 12% humidity.
Toughness: It is a long fiber with 2.6 in the Chaláis-Meudon index (Monnin).
Durability: It is classified as a non-durable species against putrefaction and susceptible to insect attack.
- Volumetric contraction coefficient 0.45% moderately nervous wood.
- Compressive strength: 357 kg / cmtwo
- Static flexural strength: 632 kg / cmtwo
- Modulus of elasticity: 99.930 kg / cmtwo
Workability: Poplar wood is easy to work with both hand and mechanical tools.
- Sawn. Easy.
- Drying. Easy, although compared to natural drying there is a risk of deformation.
- Brushed. Easy, although it requires especially sharp tools. Otherwise, blurred surfaces are generated that require subsequent sanding.
- Glued. Easy.
- Nailed and screwed. Easy.
- Finish. Easy.
Price: Given the abundance of this wood and the ease with which it grows, the price of poplar is not high.
Uses of Poplar or Poplar
- Fabrication of plywood boards (plywood in English). One of the great properties of this wood is the ease with which it is possible to obtain veneers through the “unwinding of the trunk”. If we add to this that the result is very good quality veneers, it is not surprising that poplar wood is very popular for the manufacture of plywood that will later be used in high-end furniture.
- Fabrication of clusters. After obtaining the facets, the remains of the tree are crushed and used for the manufacture of cardboard.
- Wood manufacturing for structural use: laminated and microlaminated beams. It is still in limited use, but expanding.
- Manufacture of wooden containers and boxes.
- Pulp of paper.
- Internal furniture.
- Musical instrument.
