- Common plywood: Plywood for general purposes, suitable for common usage scenarios with no special performance requirements.
- Special plywood: Plywood with certain special properties, applicable to specific purposes. Such as marine plywood, fire-retardant plywood, aviation plywood, etc., which all fall into this category.
- Aviation plywood: A type of special plywood made by combining veneers of birch or other tree species with similar material properties and phenolic resin film paper through pressing. It is mainly used in the manufacturing of aircraft components, requiring uniform material, high strength, and properties such as water resistance, weather resistance, and antibacterial ability.
- Marine plywood: A kind of high water-resistant special plywood made by hot-pressing and gluing surface layers impregnated with phenolic resin adhesive and core layers coated with phenolic resin adhesive. It is mainly used in the manufacturing of ship components and can maintain stable performance in the humid and corrosive marine environment.
- Composite plywood: A type of wood-based panel where the core layer (or certain specific layers) is composed of materials other than veneers or solid wood, but there are at least two layers of mutually staggered veneers on each side of the core layer, which are assembled and glued together. It combines the characteristics of plywood and other core layer materials.
- Symmetrical structure plywood: Plywood where the corresponding veneers on both sides of the central layer are identical in terms of tree species, thickness, grain direction, and physical and mechanical properties. It has a stable structure and balanced performance.
- Fire-retardant plywood: Plywood and its surface decorative products whose combustion performance meets the B1 level requirements in GB 8624. It has a certain flame-retardant ability and can be used in places with fire protection requirements.
- Insect-resistant plywood: Special plywood that has the function of preventing insect infestation by adding insect repellents to the veneers or adhesives, or by treating the products with insect repellents. It can be used in environments prone to insect erosion.
- Preservative-treated plywood: Special plywood that has the function of preventing fungal discoloration and decay by adding preservatives to the veneers or adhesives, or by treating the products with preservatives. It is often used in humid environments where decay is likely to occur.
- Bamboo plywood: Plywood made from bamboo materials in accordance with the principles of plywood composition, including bamboo strip plywood, bamboo sliver plywood, bamboo woven plywood, bamboo curtain plywood, composite bamboo plywood, etc.
- Bamboo strip plywood: Bamboo plywood made by applying glue, assembling blanks, and pressing with bamboo strips as the constituent units.
- Bamboo sliver plywood: Bamboo plywood made by applying glue, assembling blanks, and pressing with bamboo slivers as the constituent units, including bamboo woven plywood, bamboo curtain plywood, and bamboo sliver laminated plywood, etc.
- Bamboo woven plywood: Bamboo plywood made by interlacing bamboo slivers to weave into bamboo mats, then applying glue, assembling blanks, and pressing.
- Bamboo curtain plywood: Bamboo plywood made by weaving bamboo slivers into bamboo curtains, then applying glue, assembling blanks, and pressing.
- Composite bamboo plywood: Bamboo plywood made by applying glue to different constituent units such as bamboo strips, bamboo slivers, and bamboo veneers, then assembling blanks in a certain order and pressing.
- Wood-bamboo composite plywood: Plywood made by processing bamboo and wood into various sheet materials, applying glue, then assembling blanks and pressing. It combines the characteristics of bamboo and wood.
- Class I plywood: Weather-resistant plywood that can pass the boiling test and is used in outdoor conditions, with good weather resistance and water resistance.
- Class II plywood: Water-resistant plywood that can pass the 63℃±3℃ hot water immersion test and is used in humid conditions, applicable to relatively humid environments.
- Class III plywood: Non-moisture-resistant plywood that can pass the dry test and is used in dry conditions, suitable for indoor dry environments.
- Interior plywood: Plywood made with urea-formaldehyde resin adhesive or adhesives with equivalent performance. It cannot withstand long-term water immersion or excessive humidity and is limited to indoor use.
- Exterior plywood: Plywood made with phenolic resin adhesive or resins with equivalent performance as adhesives. It has weather resistance, water resistance, and high humidity resistance, and is suitable for outdoor use.
- Structural plywood: Plywood that can be used as load-bearing structural components of buildings, with high strength and stability.
- Plywood for concrete formwork: Plywood that can be used as a mold for concrete forming. It needs to have a certain degree of hardness, wear resistance, and good demolding performance.
- Long-grain plywood: Plywood where the grain direction of the face veneer is parallel or approximately parallel to the length direction of the panel.
- Cross-grain plywood: Plywood where the grain direction of the face veneer is parallel or approximately parallel to the width direction of the panel.
- Multi-plywood: Plywood made by assembling and pressing five or more layers of veneers.
- Molded plywood: Non-planar plywood made by forming a blank with glued veneers according to certain requirements and hot-pressing it in a mold of a specific shape. It can be used to manufacture components with special shapes.
- Scarf joint plywood: Plywood where the ends along the grain direction are processed into bevels, and then glued and lapped to extend the length. It can be used to increase the length of the board.
- Finger joint plywood: Plywood where the ends along the grain direction are processed into finger joints, and then glued and joined to extend the length. It has high joint strength and a relatively neat appearance.
