Moreover, the affordability of formaldehyde resins enables the production of a wider range of engineered wood products, increasing their accessibility to consumers across various industries.

No 04: Improved Moisture Resistance

With improved moisture resistance, your engineered wood products will withstand high humidity and moisture levels without swelling or warping, making them a reliable and durable choice for any environment.

This is due to the presence of formaldehyde in the adhesive used to manufacture the products, which reduces the absorption of moisture.

This characteristic is particularly important in environments with high humidity or moisture levels, where traditional wood products could easily degrade.

No 05: Increased Fire Resistance

Formaldehyde-based resins are commonly used in the production of engineered wood products to make them less prone to ignition and slow down the spread of flames.

This is particularly useful in applications where fire safety is a concern, making engineered wood a popular choice for both residential and commercial construction.

No 06: Longevity and Durability

You may be concerned about the longevity and durability of your construction project, but using formaldehyde-based adhesives in your engineered wood products can ensure that they maintain their structural integrity over time.

Formaldehyde resins have binding properties that create a strong bond, making engineered wood products resistant to stress, impacts, and temperature variations. This durability ensures that your project will last. In fact, formaldehyde-based adhesives contribute significantly to the longevity of engineered wood products.

No 07: Compliance with Standards and Regulations

If you want to ensure that your indoor environment meets safety regulations, it’s important to consider the compliance of the adhesives used in your construction project.

Engineered wood products using formaldehyde-based adhesives are designed to meet certain standards and regulations, such as emission standards, established by various countries and regions.

How can engineered wood be mitigated for formaldehyde emissions?

How can engineered wood be mitigated for formaldehyde emissions

To mitigate formaldehyde emissions from engineered wood, there are several strategies you can use.

  • Use Low-Formaldehyde Resins

In an era of smog-filled cities, using low-formaldehyde resins in engineered wood products is as refreshing as breathing fresh air. These resins contain reduced levels of formaldehyde or are free from added formaldehyde altogether, resulting in a significantly lower potential for emissions.

By opting for low-formaldehyde or no-added-formaldehyde (NAF) resins, manufacturers can ensure that the overall formaldehyde content in the final product is reduced, thus mitigating any potential harm to the environment and human health.

This effective solution promotes sustainable and responsible manufacturing practices, and it’s essential to consider when choosing engineered wood products.

  • Emission Testing and Certification

Independent testing agencies assess the formaldehyde emissions from the products and provide certifications based on their performance.

Certifications like the California Air Resources Board (CARB) Phase 2 or the Japanese JIS/JAS standards signify lower formaldehyde emissions and can help consumers make informed decisions.

Manufacturers subject their engineered wood products to rigorous testing to ensure compliance with formaldehyde emission standards and regulations. With these certifications, consumers can be assured that the engineered wood products they choose are safe for their health and the environment.

  • Improved Production Processes

You can reduce formaldehyde emissions by refining production processes, such as controlling temperature, pressure, and resin application, and improving equipment and ventilation systems. These process optimizations can help minimize the amount of formaldehyde used and emitted during manufacturing.

  • Formaldehyde Scavengers

Incorporating formaldehyde scavengers into your resin formulation can greatly reduce the amount of harmful chemicals released into the air, improving the overall safety of your wood products.

These scavengers work by reacting with formaldehyde molecules and trapping them within the wood product, preventing their release into the air.

Here are three benefits of using formaldehyde scavengers: 1) Lowering emissions and improving indoor air quality. 2) Meeting regulatory requirements and industry standards. 3) Enhancing the durability and stability of the wood product.

  • Proper Ventilation

To ensure the safety of your indoor environment, it’s important to have proper ventilation. This can be achieved by using fans or air purifiers to help dilute and remove harmful chemicals like formaldehyde. Adequate ventilation is especially important when dealing with engineered wood, which can emit formaldehyde.

Proper airflow can aid in reducing formaldehyde levels indoors, whether it’s during manufacturing, installation, or in occupied spaces. Ventilation systems like exhaust fans and air purifiers can help dilute and remove formaldehyde from the indoor environment.
