Environmental Protection Level

ENF has obtained dual certification from the US CARB and EPA-NAF for formaldehyde-free products. Its TVOC emission level significantly exceeds the national standard GB/T 35601-2017, as well as the standards set by the US EPA and the EU CEN. The base material contains no added formaldehyde or benzene derivatives, ensuring health and environmental friendliness.

Fire resistance

It can meet the European and American Class A fire protection requirements / domestic Class B1 fire protection requirements

Moisture resistance

It meets the Class I waterproof standards of BS1088-2018 and GB/T 9846-2015. After repeated boiling tests, the substrate remains stable without delamination, exhibiting high water resistance and stability, effectively resisting damage to the board from humid environments.

Deformation resistance

Multi-layer interlaced structure enhances dimensional stability and reduces the risks of cracking, warping, and deformation

Seawater immersion test

It can undergo long-term seawater immersion durability testing, with testing items including penetration, adhesive layer durability, delamination, water absorption and expansion, dimensional stability, etc

Adhesive performance

"Ancient Method Nuoyan - Long-Lasting Functional Board" inherits the intangible cultural heritage "sticky rice mortar" technique from the Forbidden City in Beijing and the Great Wall. It is forged into a pure natural nuoyan adhesive through modern high-temperature and high-pressure processes, forming a dense inorganic adhesive layer between the board layers. The product is environmentally friendly and meets leading indicators such as ENF+ and TVOC. It has also obtained international certifications such as Japan's F4 Star, UK's 717, and Taiwan's CNS1349, achieving long-lasting multi-functional protection.
