Phenolic plywood is an increasingly popular material in the construction industry due to its exceptional mechanical properties and weather resistance. It is frequently used for bridge, wall and roof construction in a wide variety of formwork applications.
Phenolic plywood is made of multiple layers of paper impregnated with phenolic resin, an extremely resistant synthetic material. These layers are bonded together with adhesive and subjected to pressure and heat to create a rigid, durable sheet. The result is a material that is stronger and more durable than wood or plywood.
Benefits of phenolic plywood
One of the main benefits of phenolic plywood as formwork is its high mechanical strength, which allows it to withstand the loads and vibrations that occur during the concrete pouring process. In addition, its surface is smooth and uniform, which helps to achieve a high quality finish on the surface of the concrete.
Another important advantage is its durability and resistance to moisture. Phenolic plywood is a waterproof material that does not swell or deform when exposed to water, making it ideal for use in concrete structure construction.
Phenolic plywood is also easy to handle and cut, which makes it ideal for adapting to different shapes and sizes of concrete structures. In addition, it is a lightweight material that facilitates its transport and handling on site.
In summary, phenolic plywood is a high-strength, durable and easy-to-handle material that is perfectly suited to the requirements of concrete structure construction. Its use as formwork enables the creation of high quality structures with long-term durability.
Technical characteristics
Phenolic plywoods used in construction have several features that make them very useful in this area. Some of the most important features are:
Moisture resistance: phenolic paper used as adhesive in plywood provides high moisture resistance, making it ideal for use in exterior construction and in humid environments.
Wear resistance: phenolic plywoods are highly resistant to wear and abrasion, making them ideal for use in high traffic applications such as floors and walls.
Dimensional stability: phenolic plywood offers excellent dimensional stability, which means that it does not warp or shrink with changes in temperature and humidity.
Fire resistance: phenolic plywoods are also highly fire resistant, making them ideal for use in applications where this feature is required, such as building construction.
Versatility: phenolic plywood can be manufactured in a wide variety of sizes and shapes, making it very versatile and useful in a wide variety of construction applications. They can also be treated with finishes to give them an attractive aesthetic appearance.
