Parameters

Details

Raw Materials

Usually made from various wood species such as poplar, birch, eucalyptus, pine, etc. The choice of wood species affects the quality, strength, and appearance of the plywood.

Structure

Consists of three or more layers of thin wood veneers glued together with the grain directions of adjacent layers perpendicular to each other. This structure provides good stability and strength2.

Sizes

Common sizes include 1220×2440mm, 1200×2400mm, etc. Thicknesses typically range from 3mm, 5mm, 9mm, 12mm, 15mm, 18mm to 25mm, etc. Custom sizes are also available according to specific requirements12.

Grades

Can be divided into different grades such as AA, AB, BB, etc., depending on the quality of the veneers, the presence of knots, cracks, and other defects. Higher - grade plywood has fewer defects and better appearance and performance.

Glue Types

- Phenolic glue: Offers excellent waterproof and heat - resistant properties, suitable for outdoor and high - humidity applications.

- Melamine glue: Provides good waterproof and decorative properties, often used in furniture and interior decoration.

- Urea - formaldehyde glue: Commonly used, with moderate cost and performance, but its formaldehyde emission needs to meet relevant environmental standards. There are also low - formaldehyde or formaldehyde - free glues available, such as plant - starch - based glues, which are more environmentally friendly.

Formaldehyde Emission

Should meet relevant international and domestic standards, such as the European E0 (≤0.5mg/L), E1 (≤1.5mg/L) standards, and the Chinese GB/T 39600 - 2021 standard. The lower the formaldehyde emission, the more environmentally friendly the product2.

Density

Generally ranges from 500kg/m³ to 800kg/m³, depending on the wood species and production process. Higher - density plywood usually has better strength and durability.

Moisture Content

Typically controlled within the range of 6% - 12%. Appropriate moisture content is crucial for preventing warping, cracking, and mold growth of the plywood.

Strength Properties

- Bending strength: Refers to the ability of the plywood to resist bending deformation under load. It is related to the type of wood, the number of layers, and the glue quality.

- Shear strength: Indicates the ability of the plywood to resist shear forces parallel to the plane of the board.

- Tensile strength: Measures the ability of the plywood to resist stretching forces. These strength properties determine the application scenarios and load - bearing capacity of the plywood.

Surface Finish

Can be left natural, or it can be finished with various treatments such as sanding, polishing, painting, laminating with melamine - faced paper, or applying a veneer to improve its appearance, smoothness, and wear resistance.
