Plywood core species & blend density

Compare Vinawood planning densities for single-species cores, then mix species by share (%) or any relative weights (e.g. 30 + 70 gives the same blend as 3 + 7). The result is a volume-weighted average density — useful for logistics estimates before you have a mill COA. Use packing or CBM with Custom density and paste the blended value.

Blend density calculator

Enter two or more species with positive shares. Shares do not need to sum to 100 — only the ratio matters. Use "Normalize to 100%" to rewrite rows as percentages for documentation.

Preset mixes (e.g. Styrax + Acacia) in other calculators use factory-style averages. This tool is for arbitrary percentages. Structural and glue-line performance still depend on the full panel construction — density alone does not certify a grade.

Frequently Asked Questions

What are the main plywood core species from Vietnam?
Vietnam primarily uses three core species: Acacia (550–600 kg/m³), Eucalyptus (650–750 kg/m³), and Styrax (480–520 kg/m³). Acacia is the most commonly exported due to abundant FSC-certified plantation supply. Blended cores combining two or more species are also common.
Why does plywood core species matter?
Core species affects weight (impacts shipping cost per container), density (impacts structural strength), and price. Eucalyptus core is heavier and stronger but fits fewer sheets per container. Styrax core is lighter, allowing more volume per shipment but with lower density.
What is a blended core in plywood?
A blended core uses veneers from multiple wood species layered together. For example, a 70% Acacia / 30% Eucalyptus blend combines the cost-effectiveness of Acacia with the strength of Eucalyptus. The resulting density is the volume-weighted average of the component species.
