| Summary: | Formaldehyde in the indoor air is one of the chemicals causes health risk, that’s why it is strived to reduce formaldehyde emissions from different wood products. There are many chemical compounds in the bark, including tannins, which can react with formaldehyde. The aim of this study was to reduce the formaldehyde emission from HDF with mixing poplar bark powder into the raw material. 2, 4, 6 and 8% (based on dry weight). Populus ×euramericana cv. Pannónia bark was mixed to the fibers, and HDF panels were manufactured with urea-formaldehyde resin. Mechanical properties; color change and formaldehyde release were measured. Contrary to expectations the mixed bark didn’t reduced the formaldehyde emissions, but the mechanical properties deteriorated by the bark powder.
