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.
| Species | Share | ρ (kg/m³) | |
|---|---|---|---|
| 580 | |||
| 650 |
Blended planning density
615.0 kg/m³
Mix total (sum of shares): 100.0000
- Acacia50.0% of mix → contributes 580 kg/m³
- Eucalyptus50.0% of mix → contributes 650 kg/m³
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.
