Wallpaper base film is a commonly used material in house decoration, does the base film contain formaldehyde? Today, PChouse will answer them for you.
The base film contains a certain amount of formaldehyde. But this does not come from the base film material itself, but from the adhesive. Because the base film is to be pasted on the wall, it needs an adhesive, and the adhesive generally contains formaldehyde.
Among them, adhesives are mainly divided into organic solvent type and water-based type. Organic solvent-based adhesives not only contain formaldehyde, but in most cases also contain organic volatiles such as toluene and xylene. In recent years, the environmentally friendly adhesives on the market are mostly water-based, such as glutinous rice adhesives, which are more environmentally friendly, but still add formaldehyde as preservatives, so more or less formaldehyde is released. However, the formaldehyde in this type of adhesive has two characteristics: one is that the release amount is relatively low, and the other is that the release period of formaldehyde is relatively short, generally about half a year.
