Which Organization Proposed the ENF Grade Standard?
The concept of "ENF grade" was first proposed by the national
organization of China.
On October 1, 2021, the recommended national standard GB/T 39600-2021
"Formaldehyde emission grading for wood-based panel and finishing
products" was officially implemented. The standard was proposed by China
National Forestry and Grassland Administration and issued by China State
Administration for Market Regulation and China Standardization Administration.
GB/T 39600-2021 "Formaldehyde emission grading for wood-based panels
and finishing products" applies to engineered wood and their products,
including MDF (medium density fiberboard), particle board, plywood, veneers,
wooden doors, floorings, etc., and specifies the grading requirements, test
methods and judgment rules for formaldehyde emission.
What Are the Formaldehyde Emission Requirements For
ENF-Grade Wood-Based Panels?
GB/T 39600-2021 "Formaldehyde emission grading for wood-based panels
and finishing products" classifies the formaldehyde emission of indoor
artificial boards and their products into E1, E0 and ENF three levels, of
which, ENF level is the most strict level. In other words, ENF level manufactured
boards have the lowest formaldehyde emission. NF is the abbreviation for "no
formaldehyde". ENF grade has been the world's most stringent environmental
protection standard for engineered wood nowadays.
According to the experimental method specified in the standard, with formaldehyde
emission ≤ 0.025 mg per cubic meter, the manufactured board
can reach ENF level standard; with formaldehyde emission ≤ 0.050 mg
per cubic meter, the composite wood can reach E0 level standard; with formaldehyde
emission ≤ 0.124 mg per cubic metre, the wood product can
reach E1 level standard.
What is the significance of the ENF grade standard
for the wood product industry?
Standards have a huge impact on the quality. The higher the national
standards are, the better wood-based panels will be manufactured. The ENF grade
standard is currently the most stringent formaldehyde limit requirement for
wood-based panels in the world. The introduction of this standard will actively
promote the production of low-formaldehyde and healthier composite wood
products. It promotes the upgrading of environmental protection indicators in
China's wood product industry.
This move undoubtedly means the determination of China's State Forestry and
Grassland Administration to improve the quality of China's wood-based panels
and their products. It is a vivid example of protecting consumer rights by
transparent standards.
Guangxi Xingda Chemical Helps Produce
Low-Formaldehyde Impregnated Paper
Guangxi Xingda Fine Chemicals Ltd. currently has two formaldehyde-reducing
functional additives that can reduce the content of free formaldehyde from the
source. They effectively lower the release of formaldehyde in the impregnated
paper for wood-based decoration panels, and thus improve the environmental
protection level of the finished wood product. At the same time, the
formaldehyde removal agents of Guangxi Xingda Fine Chemicals do not affect the
quality and performance of the impregnated paper.
The wood-based panel market has fierce competition today. And consumers'
requirements for home decor are also more strict. Welcome to send inquiries
about the formaldehyde-reducing agent developed by Guangxi Xingda Chemical. Let
us work together to enhance the competitiveness of your impregnating paper
products and create a green wood-based panel market!
