Which is better, EO or ENF boards? How to distinguish between ENF and EO boards?

ENF grade boards are good. Currently, E0 grade is the highest national environmental protection standard, but in October of this year, the country will introduce a new national standard, ENF grade, which is the formaldehyde-free grade. This standard will become the most stringent environmental protection standard in the world.

ENF grade boards are more environmentally friendly than E0 grade boards.

ENF grade boards have a formaldehyde emission level of ≤0.025mg/m³.

E0 grade boards have a formaldehyde emission level of ≤0.050 mg/m³.

The environmental protection levels of the boards, from highest to lowest, are: ENF, E0, and E1.

How can you tell if a board material is environmentally friendly?

Environmental rating: Check the environmental rating label on the board. In some countries or regions, boards usually have corresponding environmental certification marks, which indicate that the board meets specific environmental standards.

VOC emissions: VOCs (volatile organic compounds) are chemical substances harmful to human health and the environment. Inquire with the board supplier whether they have conducted VOC emission tests and ensure they comply with relevant national or regional standards. Low-VOC emission boards are more environmentally friendly for indoor air quality.

Formaldehyde content: Formaldehyde is a common harmful gas, especially in wood-based panels such as plywood and MDF. It's important to understand whether the formaldehyde emission levels of the panels meet national or regional standards. Some environmentally friendly panels use low-formaldehyde or formaldehyde-free adhesives.

Production Process: Understand the production process of wood-based panels. Some environmentally friendly panels employ sustainable and environmentally friendly manufacturing methods, including the use of recycled materials, energy conservation, and waste reduction.

Reliable suppliers: Choose reputable board suppliers who will provide clear information about the environmental friendliness of their products and support relevant certification documents.

In addition, the following methods can be used to make a preliminary judgment when purchasing boards:

Look: Check the environmental protection grade certificate of the board material.

Smell: Smell the board to see if it has a pungent odor. If there is a strong chemical odor, it may mean that the board contains a high content of volatile substances.

The ENF grade board standard is the latest standard customized by a national authoritative institution. This standard requires that the formaldehyde emission of the board be ≤0.025mg/m³. The E0 grade board standard is also customized by a national authoritative institution, with a formaldehyde emission of ≤0.05mg/m³. Both are currently the most environmentally friendly standards.

Formaldehyde is the most concerning factor during the renovation process. In the past, when choosing building materials, people knew about E1 and E0 grades. Now, we also need to know about a brand new environmental protection grade: ENF grade.

Based on data and standards, ENF-grade boards have been tested by national authoritative institutions.

Personally, I recommend choosing ENF-grade boards , as they are more environmentally friendly and safer. Home renovation is a lifelong commitment, so of course you should choose good raw materials. Besides meeting the highest environmental standard of ENF, Panxu also offers an excellent user experience.

For most home renovations, E0-grade boards are considered quite good. However, ENF-grade environmental standards represent the highest level of environmental protection under the new national standard. The new standard for formaldehyde emission limits for boards is ≤0.025mg/m³, which is currently the most stringent environmental standard. For home renovations, ENF-grade boards are generally recommended, even though they are the most expensive. Since home renovations are not frequent, healthy boards ensure a healthy home environment for the family.

From a more environmentally friendly perspective, ENF-grade boards are the obvious choice.

The ENF standard has stricter requirements, with formaldehyde emission limits half that of the E0 standard. Therefore, the emergence of the ENF environmental standard signifies that China's formaldehyde emission limits for engineered wood products have jumped to the highest level in the world. This demonstrates that the ENF standard is the most environmentally friendly and the most suitable choice for home decoration.

From an economic perspective, if your budget allows, it's recommended to choose ENF-grade boards, as they are more environmentally friendly and create a healthier home environment. If your budget is limited, E0-grade boards are a good option, as they are also environmentally friendly and cheaper than ENF-grade boards.

E0 grade formaldehyde emission is ≤0.050mg/m³, and ENF grade formaldehyde emission is ≤0.025mg/m³. Therefore, ENF grade is superior to E0 grade and represents the highest environmental protection standard currently available. Brands that upgraded their product environmental standards before the official promulgation of the new national standard for ENF grade, such as those producing solid wood veneer OSB boards and ENF grade LSB high-energy home furnishing boards, all comply with the new national standard. For our healthy lives, we should prioritize ENF grade boards as home decoration materials.

So what are the differences between ENF-grade and E0-grade environmentally friendly boards? They often use urea-formaldehyde resin glue and phenolic resin glue. Traditionally speaking, these are essentially glues synthesized from urea and formaldehyde. To exaggerate a bit, imagine a bucket half full of urea and half full of formaldehyde; mix them together, and that's the glue. When we use urea-formaldehyde resin glue to bond the boards, the formaldehyde naturally remains within the boards. Previously, formaldehyde was controlled by, for example, filling a board with... For a given cubic meter of formaldehyde, the edge-sealing technology is used. So the difference between big brands and small brands is that, just like blowing up a balloon, everyone knows that a balloon will naturally deflate after being left for a long time. It's the same with formaldehyde in wood-based panels. Through years of release, the formaldehyde will naturally accumulate. However, it's important to understand that within a certain time and space, the less formaldehyde released, the lower the degree of harm to human health. Therefore, the tighter the edge-sealing technology, the more tightly the balloon's opening is tied, and the slower it deflates. This refers to the previous EO-grade boards. So, what is the principle behind the environmental control technology for ENF-grade boards? It uses MDI formaldehyde-free adhesive. MDI formaldehyde-free adhesive is a patented adhesive developed by Wanhua Group. Its chemical composition contains no formaldehyde, hence the name "formaldehyde-free adhesive." After bonding the boards together, it requires highly sophisticated equipment; ordinary equipment cannot process it. Boards made with MDI adhesive have extremely low formaldehyde content, even negligible, due to its chemical composition... The formaldehyde content is unrelated to the material itself. Therefore, when using boards, we should prioritize ENF grade. For example, the price difference between ENF grade boards and E0 grade boards offered by Quanyou Home Furnishings is less than 100 yuan. So for a family, for a cabinet of 20 to 30 square meters, the price difference is less than 2,000-3,000 yuan. However, it can effectively reduce the formaldehyde emission in your home. Using formaldehyde-free and environmentally friendly boards is the preferred direction for the future. Therefore, please be sure to choose between E0 and ENF grade boards.

E0 grade is formaldehyde-free. Before the introduction of ENF grade, E0 was the highest standard. After the new national standard was released, ENF grade was defined as the highest environmental protection level. Therefore, ENF grade boards are more environmentally friendly than E0 and E1 grade boards. Especially for homes with elderly people or children, it is essential to be more careful in selecting materials and pay more attention to environmental protection. Everyone knows the harm of formaldehyde to the human body. As children, we all want to give our elderly parents the best life after a lifetime of hard work. So, if your renovation budget allows, you must choose boards that meet the ENF grade standard. The next best option is E0 grade boards.

When renovating your home, it's always safer to choose boards with a higher environmental protection rating. The highest environmental standard in my country is currently the ENF standard, which requires formaldehyde emissions from boards to be ≤0.025mg/m³. Therefore, I highly recommend choosing ENF-grade boards. When we renovated, a friend recommended ENF-grade LSB high-energy home furnishing boards, and they've been excellent. Formaldehyde tests after the renovation easily passed, thanks to this great board! I highly recommend it to you!

E0 grade is formaldehyde-free. Before the introduction of ENF grade, E0 grade was the highest standard. After the new national standard was released, ENF grade was defined as the highest environmental protection level. Therefore, ENF grade boards are more suitable for home decoration. Many brands in my country can achieve this environmental protection level by using high-quality pine wood and formaldehyde-free MDI eco-friendly glue. They not only have excellent environmental performance but also effectively resist bacteria, giving us a healthier and more environmentally friendly home life.

Both E0 grade and ENF grade boards are environmentally friendly engineered wood products, but their standards are different and there are some key differences between them.

E0 grade boards are a type of engineered wood-based panel that meets the highest environmental protection standard and has the lowest formaldehyde emission level in China. According to my country's GB/T standard, the formaldehyde emission of E0 grade boards should not exceed 0.050 mg/m³. Such boards are safe, reliable, and environmentally friendly.

ENF-grade boards are more stringent than E0 boards in terms of formaldehyde emission, requiring that the formaldehyde emission level not exceed 0.025 mg/m³. Therefore, ENF-grade boards are better in terms of formaldehyde emission.

Although ENF-grade boards have stricter requirements, E0-grade boards also meet my country's stringent standards and are slightly cheaper than ENF-grade boards, making them safe to use. The choice of which environmentally friendly grade of engineered wood product to use depends on your specific needs and budget.

ENF grade is stipulated by the new national standard, which states that the formaldehyde emission of indoor wood-based panels and their products is less than or equal to 0.025mg/m³. It is the strictest environmental protection standard for wood-based panels in the world , and is definitely healthier and more environmentally friendly than E0 grade.
