OPPEIN formaldehyde-free added substrate material has been awarded NAF formaldehyde-free added exemption certification by California Air Resources Board (CARB).

Earlier, OPPEIN has obtained NAF formaldehyde-free added exemption certification from the US Environmental Protection Agency (EPA). OPPEIN formaldehyde-free added substrate material has become one of the few environmentally friendly substrate material in the custom home industry that has obtained dual certification.

Tested by domestic authoritative institutions, the formaldehyde emission of OPPEIN aldehydefreeadded substrate material is less than 0.005mg/m³, which is close to zero, with the leading edge.

OPPEIN took the lead of the industry to comprehensively upgrade the environmental protection level of substrate material without aldehydes and reduced the terminal price. The era of the high environmental premium is gone.
