Currently, the main reason for excessive formaldehyde emissions from engineered wood products is cost. Choosing inferior adhesives can greatly reduce costs, but the formaldehyde emissions will increase exponentially.
Formaldehyde release has long been a persistent problem in the engineered wood products industry. This is because the manufacture of traditional engineered wood products requires the use of urea-formaldehyde resin adhesives, which are made from formaldehyde. Even with the best adhesives currently available, the produced boards will still fail to meet the "zero formaldehyde" standard due to trace amounts of formaldehyde naturally present in the wood itself.
However, since natural wood also contains a certain amount of formaldehyde, it means that trace amounts of formaldehyde will not harm human health. Therefore, consumers can choose boards that are as close to "zero formaldehyde" as possible.
According to national standards, boards with an environmental protection rating of E1 or higher can be used for interior decoration. E1 grade boards use a unique patented adhesive formulation with high-solids content resin that has superior performance, ensuring the physical and mechanical properties of the boards. At the same time, it ensures that the free formaldehyde content of the boards meets the highest global environmental protection requirements. Furthermore, the boards utilize the latest technology, adding solid formaldehyde-reducing powder before the core layer mixing machine to further reduce the formaldehyde content inside the board.
Experts point out that to achieve near-zero formaldehyde emissions in wood-based panels, two aspects need to be addressed: First, using more environmentally friendly adhesives to eliminate formaldehyde at the source; second, conducting formaldehyde emission testing on the products to ensure quality control and guarantee that only products sold meet standards. Therefore, simply using high-quality adhesives cannot guarantee 100% formaldehyde emissions; more stringent testing is necessary before products are released to the market. Consequently, the environmental protection level of these panels far exceeds the market average.
Environmentally friendly building materials can be identified from the following aspects:
1) Smell for any pungent odor.
2) Check if there is a certificate issued by a national authoritative body.
3) Is the adhesive used environmentally friendly?
Of course, consumers rarely buy engineered wood panels directly during home decoration. However, modern furniture, cabinets, and wardrobes widely use engineered wood panels, making it difficult for many consumers to find satisfactory and healthy furniture. Actually, it's quite simple. First, choose furniture from well-known brands. This method may not guarantee 100% environmental friendliness, but major brands have strong financial backing and use high-quality panels. Second, choose environmentally friendly panels, such as those from the top ten engineered wood panel brands.
