When it comes to the history of plywood boards, it was around 1905 when this sort of engineered wood first entered the market. It is constantly being upgraded in quality and appearance alongside the advancement of contemporary machinery. As a result, this engineered wood has gained popularity as a material in several industries, including furniture production, building, and manufacturing. ADX has compiled a list of frequently asked questions in this post. Find out more information about this top engineered wood.
Plywood – Sustainable choice for your project
Engineered wood, which is primarily made from short-lived timber species, is known as a source of sustainable materials. This lessens the demand for using precious and perennial wood. The best alternative to natural wood is plywood, which is highly recognized for its sturdiness, consistency of quality, and variety of applications. Three main parts form this kind of board:
- Core: many thin layers of wood – called “plies” are glued together with adjacent layers
- Surface: Melamine paper, film paper, laminate, veneer,…
- Adhesives: Urea Formaldehyde, Melamine Urea Formaldehyde, Phenol Formaldehyde
Frequently Asked Plywood Questions
How to choose the appropriate board structure?
The structure is a crucial element assisting board in maximizing powers in each particular field. The three commonly used techniques of layering panels are LVD, LVL, and LVB.
LVD – Normal structure
Advantages: The core can remain balanced if stacking the LVD board. The wooden plies bond with one another avoiding being warped and bubbled. The board surface is kept level and more pressure-resistant as a result.
Application: Flat load-bearing furniture like table tops, chairs, cabinet tops, etc. are primarily made of this material.
LVL – Laminated Veneer Lumber
Advantages: Thanks to the unique layering technique, the LVL board creates a consistent structure that can withstand strain in one direction quite effectively and is easier to bend.
Application: Long wooden bars known as LVL are frequently manufactured for use in building frame systems and curved furniture.
LVB – Laminated Veneer Board
Advantages: LVB features layers designed to suit each requirement. Its remarkable qualities—such as its high bearing capacity and minimal warping and blistering—are enhanced.
Application: Bed frames, cabinets, chair frames, and other types of furniture are typically made using LVB board.
How do coated surfaces impact the quality of a board?
A veneer is a thin board that ranges in thickness from 0.3 to 0.6 mm. The quality of the veneer will vary depending on the type of wood used. Poplar and birch veneer are the most widely used varieties. It usually has applied layers of UV/oil paint to improve water resistance and termite resistance.
Melamine paper is decorative paper impregnated melamine glue, also known as decorative paper or Titanium Oxide Paper. Its surface features a variety of grain and color patterns, giving an appealing look in addition to a prolonged lifespan. It can withstand about 24 -48 hours of boiling while remaining stable.
The film is considered the type of coating surface that provides the best quality of engineered wood today, made from paper impregnated Phenol Formaldehyde waterproof glue. The highlight of film faced sheet is that it is highly durable, difficult to scratch and can withstand boiling for up to 72 hours without delamination.
Why is the quantity of core plies odd?
The quantity layers of every panel are often odd numbers of 3, 5, 7, 9, or 11 thin plies. This design enables the panel to create a central core layer to create equilibrium, reducing warping, shrinkage, and bubbles, which is a common problem with engineered wood in general.
Does all plywood have the same water resistance?
Water resistance varies across different types of boards and is influenced by many factors, including the type of glue used, the coating surface, the type of raw wood, and the manufacturing process. The board’s ability to withstand moisture and temperature changes is also particularly impacted by adhesive.
What are the different types of glue?
UF – Urea Formaldehyde
It is a widely used glue in the interior material and has the advantages of speedy drying, economical price, and convenience of usage. Additionally, this sort of glue has drawbacks such as a weaker-than-other adhesive quality and lack of water resistance. As a result, UF is often only applied to interior panels in dry environments, away from high temperatures and direct contact with water.
MUF – Melamine Urea Formaldehyde
This type of glue is considered a level-up version of UF as the addition of melamine in the production process. Thereby overcoming the weakness of UF’s poor water resistance, providing a board that can be applied in even humid environments. Accordingly, the one using MUF glue costs more than the one using UF.
PF – Phenol Formaldehyde
PF has been shown to provide the ideal product quality, offering not just a strong bond but also excellent water resistance. This specific type of adhesive is frequently used in building, exterior, marine, etc. Panels utilizing UF glue can endure boiling for up to 72 hours without splitting. The board pricing is likewise more expensive than the other two varieties.
What is the Formaldehyde emission standard?
Engineered wood in general requires the inclusion of glue containing Formaldehyde during manufacturing. This gas harm negatively affects human health. Under the supervision of the governments of the nations, a variety of standards have been set to control the emissions from engineered wood.
|Standard||Limitation of Formaldehyde Emission||Applicable countries|
|E0/ F***||0.07ppm||Japan, Australia, New Zealand, Korea, West Asia|
|E2||0.38 ppm||Southeast Asia, North Africa|
|Carb P1||0.18 ppm||America, Canada, Europe|
|Carb P2||0.05 ppm|
*ppm stands for parts per million
