How Much Formaldehyde is Too Much in Plywood?
Plywood is a common material used in construction, furniture-making, and other industries. However, it’s essential to know that excess formaldehyde in plywood can be a health concern. But how much is too much?
- Formaldehyde is added to plywood as a preservative to prevent moisture and insect damage.
- The US Environmental Protection Agency (EPA) sets the maximum allowable emission rate for formaldehyde in plywood at 0.125 milligrams per cubic meter (mg/m3).
- Some plywood products, designed for indoor use, must meet more stringent emission standards, generally 0.08 mg/m3 or lower.
- You can find this information on product labels, certifications, or manufacturer documentation.
To assess the formaldehyde level in your plywood, you can conduct a simple test:
- Place a piece of plywood in a sealed container with a porous tube (specifically designed for formaldehyde detection) for at least 24 hours.
- Compare the color change on the tube to the color chart provided with the testing kit.
- If the tube shows a significant color change, the plywood may contain excessive formaldehyde.
When purchasing plywood, look for products with formaldehyde-free or low-emission labels, or certifications like Greenguard Gold or California Air Resources Board (CARB) Phase 2 Compliant.
- Always follow proper ventilation and handling procedures when working with plywood to minimize exposure to volatile organic compounds (VOCs).
- Regularly inspect your plywood products for visible signs of damage or degradation, which can contribute to increased formaldehyde emissions.
Can I Mitigate Formaldehyde Emissions from Plywood?
Formaldehyde emissions from plywood can be a concern for those who work or live in spaces where the material is used. The good news is that there are potential ways to reduce or mitigate these emissions.

What is the Typical Formaldehyde Content of Plywood?
Formaldehyde is a chemical frequently found in plywood, used as a bonding agent to hold the wood fibers together. Here’s some information on the typical formaldehyde content of plywood:
Types of Formaldehyde in Plywood
- Urea-formaldehyde (UF) resin: This is the most common type of formaldehyde used in plywood, accounting for about 70% of the total formaldehyde content.
- Melamine-formaldehyde (MF) resin: This type of formaldehyde is used in some plywood products, mainly for its high heat resistance and moisture resistance.
- Phenol-formaldehyde (PF) resin: This type of formaldehyde is typically used in high-quality plywood products, offering excellent resistance to chemicals and heat.
Formaldehyde Content Range
- Average formaldehyde content of most plywood products: 0.3% to 1.2% (3,000 to 12,000 parts per million, ppm).
- High-quality plywood products: 0.1% to 0.5% (1,000 to 5,000 ppm).
- Low-formaldehyde plywood products: <0.1% (<1,000 ppm).
It’s essential to note that these values can vary depending on the manufacturer, type of plywood, and intended use. If you’re concerned about formaldehyde exposure, look for plywood products labeled as containing lower levels of formaldehyde or those certified by organizations that set strict limits on formaldehyde content.
Does Ultem or Phenolic Resin Affect Formaldehyde Levels in Plywood?
Plywood, a popular construction material, can contain formaldehyde, a chemical linked to health concerns. Two resin types, ULTEM and phenolic, are often used in plywood manufacturing. Let’s dive into the question: Does ULTEM or phenolic resin affect formaldehyde levels in plywood?
Background Information
Formaldehyde is a known carcinogen and respiratory irritant. It’s commonly used in woodworking applications, including plywood production, as a binding agent to strengthen the material. The primary sources of formaldehyde in plywood are the phenol and urea formaldehyde resins used in the manufacturing process.
ULTEM Resin
ULTEM resin, a type of polyetherimide, is sometimes used as an alternative to phenolic resin. Compared to phenolic resin, ULTEM has a lower formaldehyde emissions rate. This is because ULTEM resin is made from a different compound, bisphenol A, which doesn’t contribute to formaldehyde formation.
Phenolic Resin
Phenolic resin is a more traditional choice for plywood manufacturing. It’s made by combining phenol and formaldehyde, creating a complex network of polymer chains. This process releases formaldehyde emissions, which can contaminate the air and surrounding environment.
Comparison and Conclusion
ULTEM resin tends to have lower formaldehyde emissions compared to phenolic resin. However, it’s essential to note that both resins can still emit some amount of formaldehyde during the manufacturing process. If you’re concerned about formaldehyde levels in your plywood, consider opting for ULTEM resin or seeking out manufacturers that use low-formaldehyde emission technologies.
