Wood cannot be formaldehyde free
Wood cannot be formaldehyde free
This is claimed by Franco Bulian, deputy director, head of the chemical laboratory and marketing director of Catas, the testing and analysis laboratory for the wood-furniture sector. In a recent article published in the trade magazine 'I love parquet', Bulian - who is also a contract professor at the University of Trieste - explains how formaldehyde is present everywhere. From the immense interstellar spaces of the universe to the cells of the human body and our own blood.
Formaldehyde of natural origin, which is also present in solid wood, albeit in small quantities. How much? "The detectable concentrations vary depending on the wood species considered and various factors including, for example, the temperature of the drying processes, the timing of these processes and the initial and final moisture content of the wood," says the deputy director of Catas, according to whom the time elapsed between drying and measurement and the intermediate storage conditions are also decisive.
Studies and data presented in the article lead to the conclusion that in general it is not possible to speak of formaldehyde free, a slogan often used for wood products. "Slogans that," Bulian warns, "should be considered very carefully both for their actual veracity, but also and above all so as not to exasperate this issue that could have negative repercussions for the entire wood and furnishing supply chain". As if to say: be careful not to confuse the natural formaldehyde present in raw wood as a negative factor. Because it is not.
