Middle Grades Birch Plywood(BB/BB & BB/CP)

Surface treatment of Middle Grades Birch Plywood (BB/BB & BB/CP)

In the field of furniture manufacturing and interior design, the surface treatment of materials has a vital impact on the appearance and performance of the final product. Middle Grade Birch Plywood (BB/BB & BB/CP) has gradually become the material of choice for designers and manufacturers due to its excellent surface properties.
One of the most notable features of birch plywood is its smooth and uniform surface. After fine sanding, the surface of BB/BB grade plywood is smooth and uniform, with almost no obvious flaws or unevenness. This high-quality surface treatment not only improves the ability of plywood to bond with various coatings and finishing materials, but also effectively reduces the amount of coating used. The finely treated surface can significantly improve the adhesion and uniformity of the coating, thereby ensuring the best appearance of the final product.
In terms of finishing, middle grade birch plywood shows excellent paintability. Its smooth surface allows it to easily accept a variety of coatings, including varnishes, paints and stains. Designers can choose a clear varnish to preserve the natural texture of the wood and show its unique beauty, or apply bright paint to achieve a personalized visual effect. No matter which finishing method is chosen, birch plywood can provide ideal effects to meet the needs of different customers, reflecting its flexibility and adaptability in design.
The surface treatment of birch plywood is not only about beauty, but also about providing additional protection. Properly treated plywood surfaces can effectively resist external wear, scratches and dirt. The application of varnish and other protective coatings can significantly enhance the water resistance and stain resistance of plywood, so that it can maintain its good appearance in wet or dirty environments. In addition, these coatings effectively block UV rays and prevent the wood from fading due to sunlight, thus significantly extending the service life of the product.
The surface treatment effect of medium-grade birch plywood is also reflected in its adaptability to environmental changes. Birch itself has good moisture resistance and stability. Even in an environment with large changes in humidity and temperature, the treated plywood can still maintain its shape and structure. This property enables birch plywood to perform well in different climate conditions, suitable for a variety of indoor and outdoor applications, and meet high standards of use.

Physical properties of Middle Grades Birch Plywood (BB/BB & BB/CP)

Middle grade birch plywood (BB/BB & BB/CP) is highly favored in furniture manufacturing, interior decoration and other applications due to its excellent physical properties. These properties not only significantly affect the service life and performance of the material, but are also directly related to the quality and appearance of the final product.
Density
The density of birch plywood is usually between 600 and 700 kilograms per cubic meter, which provides it with a good balance of strength and weight. The higher density gives birch plywood excellent compressive and bending strength, making it suitable for furniture and structural parts that bear heavy loads. At the same time, the moderate density also improves the convenience of birch plywood during handling and installation, reduces the difficulty of operation, and thus improves work efficiency.
Strength
The strength of birch plywood is one of its most important physical properties. Depending on the grade, BB/BB and BB/CP grades of plywood excel in both bending and tensile strength. Specifically, birch plywood's bending strength is usually between 30 and 50 megapascals (MPa), while its tensile strength can reach 40 to 60 MPa. This high strength allows birch plywood to effectively withstand the various pressures and impacts of daily use, significantly reducing the risk of damage caused by improper use.
Stability
The stability of medium-grade birch plywood is one of the important reasons why it performs well in a variety of environments. The material exhibits low swelling and shrinkage, which means that birch plywood's dimensions change very little under conditions of humidity and temperature changes. This feature allows birch plywood to maintain its shape and structure in wet or dry environments, avoiding problems such as warping, cracking or deformation, ensuring the long-term performance of the product.
Durability
The durability of birch plywood is one of the reasons why it is popular in furniture manufacturing and construction applications. Birch itself has good corrosion resistance and wear resistance. The processed plywood can effectively resist daily wear and the influence of the external environment during use. In addition, the surface treatment process of birch plywood can further enhance its durability, so that it can still maintain excellent performance under various conditions.
Application Fields
Medium-grade birch plywood is widely used in furniture manufacturing, interior decoration, building structure and other related fields. Its excellent physical properties make it an ideal choice for high-end furniture, cabinets, floors and wall decoration. With the increasing market demand for environmentally friendly and sustainable materials, birch plywood has become one of the important materials in modern manufacturing due to its renewable characteristics and excellent processing performance.
