Price differences between different qualities of plywood board
The price difference in plywood board mainly stems from factors such as material, manufacturing process, environmental protection level, application, and brand. Different prices correspond to different quality levels. We are committed to producing and supplying plywood, MDF sheet, particleboard, and flooring products of various specifications and grades.
The following are key influencing factors and their corresponding quality characteristics: Core Factors Affecting Plywood Price and Quality
I. Plywood Adhesive Type and Environmental Protection Level:
1. Phenolic Resin (PF Adhesive): Used for Class I (boiling water resistant) plywood. It is waterproof and weather resistant, commonly used in shipbuilding and construction formwork. It is expensive but of stable quality.
2. Urea-Formaldehyde Adhesive (UF Adhesive): Used for Class II/III (water resistant/moisture resistant) plywood. It is mostly used in interior furniture and decoration. It has a lower cost but higher formaldehyde emission.
3. Environmental Standards: Products meeting ENF grade (≤0.05mg/m³) or E0 grade (≤0.5mg/L) have lower formaldehyde emissions, higher safety, and are also more expensive.
II. Plywood Species and Structure:
1. High-quality species (e.g., birch, ash): High density, strong nail-holding power, and resistant to deformation; often used in high-end furniture or marine applications.
2. Fast-growing timber (e.g., eucalyptus, poplar): Low cost, but relatively weaker mechanical properties and durability; often used for construction formwork or packaging.
3. Number of layers and symmetry: Odd-numbered layers (e.g., 3 or 5 layers) with perpendicularly interlaced fibers provide greater stability and less deformation.
III. Plywood Thickness and Dimensions:
1. Common thicknesses: 9mm, 12mm, 15mm, 18mm, etc. Thicker layers generally indicate higher strength and price.
2. Standard dimensions are typically 1220×2440mm; non-standard sizes may incur additional costs.
IV. Plywood Surface Treatment and Decoration:
Vesseled plywood (with natural wood veneer or artificial thin wood): High aesthetic appeal; more expensive than unveneedled plywood. Sanded plywood: Good surface smoothness, suitable for direct painting, slightly more expensive.
V. Plywood Quality Control:
1. Strict quality control, higher price but reliable quality.
2. Relaxed quality control: May use inferior glue or mixed wood cores, formaldehyde exceeding standards, prone to delamination, cheaper but riskier.
VI. Plywood Purchasing Recommendations:
1. Check environmental labels: Prioritize products labeled ENF or E0 grade, and check the test reports.
2. Check workmanship: Flat surface, no bubbles, tight seams, and no cracks in the edge glue.
3. Inquire about the intended use:
– Indoor furniture → Choose Class II/III plywood;
– Humid environments (such as bathrooms) → Choose Class II or marine grade plywood.
4. Avoid low-price traps: Products priced far below market value may have excessive formaldehyde or use recycled materials.
