The density of particleboard usually ranges from 0.45 to 0.75 grams per cubic centimeter (g/cm³), depending on the classification standard, thickness and application scenario. Low-density particleboard (0.25 to 0.45 g/cm³) is suitable for light structures, medium-density (0.45 to 0.60 g/cm³) is commonly used in furniture manufacturing, and high-density (0.60 to 1.3 g/cm³) is used for load-bearing parts such as countertops or floors.
Density classification and common ranges
Low-density particleboard: 0.25 to 0.45 g/cm³, mainly used in scenarios with low strength requirements, such as temporary buildings or packaging materials.
Medium-density particleboard: 0.45 to 0.60 g/cm³, is a common choice in furniture manufacturing and construction, balancing processing performance and structural stability.
High-density particleboard: 0.60-1.3 g/cm³, common products on the market are concentrated in the range of 0.60-0.70 g/cm³, suitable for countertops, floors and other parts that require high durability.
Relationship between density and thickness
Thin boards (such as 8 mm) have higher density (0.68-0.75 g/cm³) and are used for lightweight furniture and decoration.
Thick boards (such as 38 mm) have lower density (about 0.60-0.65 g/cm³) and are more suitable for load-bearing structures.
National standards and quality requirements
According to standards such as GB/T 9846.3-2004, the density of furniture-grade particleboard shall not be less than 0.55 g/cm³ to ensure surface finish and bending strength. Environmental protection level (such as E1 formaldehyde emission ≤10 mg/100 g) also needs to be considered simultaneously.
