What does F4 Star mean?

F4 Star is an environmental protection standard, but it is not implemented and recognized by China, but comes from Japan. The environmental protection implementation standard of China's wood flooring industry is E0 (formaldehyde emission ≤0.5mg/ 100g), which belongs to the highest level of China's national standard, and it is also said to be F4 star-day standard (formaldehyde emission ≤0.3mg/ 100g), so the requirement for formaldehyde emission is higher.

In order to improve the environmental protection level of floors, some large domestic flooring brands take F4 star standard as the enterprise control standard, which is called F4 star floor. However, due to the high requirements of technology and production control, at present, icons and Beyak can really produce F4 star flooring in China. In contrast, Beyak's F4 Star flooring is technically more mature, because it has passed the CARB and GREENGUARD certifications of the United States and is an international first-line flooring brand for foreign trade export ~
