Phenolic boards and materials are in high demand today for demanding applications. Especially those that have to do with exposure to water and humidity.
Its name comes from the use of adhesives and or phenol-formaldehyde resins. This compound has a very low formaldehyde emission, in accordance with current regulations.
A disadvantage of working with phenolic materials is the increased wear on machines and saws.
Phenolic plywood board
As its name implies, it is a plywood board on which phenolic glue was used for its construction. Often, this description leads to error for generalizing too much.
It is colloquially understood that a phenolic plate is suitable for outdoor use. However, the fact that phenolic glue was used is not sufficient for outdoor use. For example, a perimeter seal is required.
Therefore, when buying it is advisable to look beyond the word phenolic. Ideally, regulations are followed. In the case of Spain, it is UNE-EN 314 where it is called “phenolic plywood” and the requirements that must be met for its use abroad.
One of the most used woods to make this type of board is birch. It is also common to find it with different characteristics: laminated outer layers, fire retardant or with a non-slip outer layer.
The density is generally between 550-700 kg / m3 depending on the wood used.
Between his forms The following stand out: Formwork, stages and exterior terraces, ramps, bodies.
Compact Phenolic boards
Sold in cardboard format, it is a compact of high density fibers, usually around 1,000 kg / m3, where phenolic resins are used.
This phenolic panel is very resistant and hard, has great resistance to moisture and flexing, is very stable and is available in a multitude of finishes. For example laminates or even veneers made of natural wood. In addition, thanks to their low porosity, they are antibacterial.
Forms highlights of the phenolic panels:
- Lockers and changing rooms for sports facilities.
- Store tasters.
- Kitchen and bathroom furniture. Countertops.
- Hospital and hotel equipment.
- On panels. It is also an excellent insulator, although there are alternatives of equal or better performance at a lower price.
