Are man-made sheets containing formaldehyde?
Adhesive, with formaldehyde. No aldehyde glue seems not much. How much formaldehyde, and the quality and amount of glue. So buy the floor, pure wood the most environmentally friendly.
The so-called adhesive is the main component of formaldehyde + urea = urea-formaldehyde resin, which itself is non-toxic harmless, but due to the different levels of production technology, formaldehyde dissolved in the degree of urea is not the same, the production process good manufacturers , Formaldehyde dissolution can reach more than 98%, but no matter how good your process, there will always be formaldehyde molecules in an unstable state, which means that the man-made plate why contains formaldehyde; that is to say, in a long time Formaldehyde is slowly released as a major factor.
Man-made sheet containing formaldehyde:
Because the plate, MDF, particleboard, wood flooring and other man-made sheet of formaldehyde mainly produced in the manufacturing process from the bonding of formaldehyde resin. This resin has a strong adhesion, to strengthen the hardness of the board, pest control, anti-corrosion function and cheap, is the first choice for the man-made sheet of raw materials. As the formaldehyde in the floor will not immediately volatilize, but because of different temperature and humidity conditions slowly volatile, volatile time up to ten years.
