Formaldehyde Emission Standards in Plywood: E0, E1, and E2

Understanding formaldehyde emission standards is crucial when selecting plywood and wood products, as it directly impacts environmental quality and human health. The E0, E1, and E2 standards specify the levels of formaldehyde released from these products.

1. E0 Grade

   • Formaldehyde Emission: ≤ 0.5 mg/L
   • Characteristics: The E0 grade is the most stringent standard, indicating almost no formaldehyde release. It is highly environmentally friendly and poses no significant health risks.
   • Applications: Used in high-environmental-standard areas such as children’s furniture, high-end furniture, and interior decoration.

2. E1 Grade

   • Formaldehyde Emission: ≤ 1.5 mg/L
   • Characteristics: The E1 grade is a widely accepted standard for environmental safety. It has low formaldehyde emissions and minimal health impact.
   • Applications: Commonly used in furniture, flooring, and interior decoration, suitable for general household use.

3. E2 Grade

   • Formaldehyde Emission: ≤ 5.0 mg/L
   • Characteristics: The E2 grade has relatively higher formaldehyde emissions, which may have some health impacts.
   • Applications: Mainly used in areas with low environmental requirements, such as packaging materials and low-end furniture. It is not recommended for long-term indoor use.

Importance of Formaldehyde Emission Standards

Formaldehyde is a harmful volatile organic compound that can cause respiratory diseases, allergic reactions, and even cancer with prolonged exposure. Therefore, selecting plywood and wood products with low formaldehyde emissions is essential, especially for environments where people live or work long-term, such as homes, schools, and hospitals.

When purchasing plywood and related wood products, understanding and choosing the appropriate formaldehyde emission grade can significantly reduce indoor air pollution and protect health.
