Plywood raw materials primarily consist of the following two components:
• Wood veneer: The primary material for plywood is typically natural wood, such as pine, poplar, birch, and eucalyptus. Different wood species have varying physical properties, such as hardness, density, and grain, which affect the performance and application of plywood.
• Adhesive: Adhesives are an essential component of plywood production, used to bond the veneers together. Commonly used adhesives include urea-formaldehyde resin glue, phenol-formaldehyde resin glue, and melamine-modified urea-formaldehyde resin glue. The choice of these adhesives directly affects the plywood's strength, water resistance, and environmental performance.
