Plywood Formaldehyde Emissions
Plywood formaldehyde emissions are determined by the glue used in production. Plywood mills use Phenolic, melamine and urea formaldehyde glue. Emission grades are Super E0, E1, CARB P2 and F4 Star.
Formaldehyde is used in glue in the manufacture of wood based panels including plywood, particle board and MDF. It is used for the formulation of wood-based panel adhesives and very hard to substitute. Formaldehyde release is very high in newly manufactured plywood. So it is important to control the quality of glue used for plywood.
European Standards for Formaldehyde
| Formaldehyde Emission Grade | Formaldehyde Emission Level |
|---|---|
| E0 Grade (Not Existing in the Standard) | ≤0.5mg/L |
| E1 Grade | ≤1.5mg/L |
| E2 Grade (Banned in China) | ≤5.0mg/L |
| JAS F4 Star (Japan) | ≤0.3mg/L |
