Is there formaldehyde in the plastic board?
Plastic board also divides very much, some have formaldehyde, and some do not have formaldehyde.Formaldehyde is mainly in the glue, including wood containing glue, furniture.
The most common plastic containing formaldehyde has the following:1) POM plastic (POM) is a kind of engineering plastics, containing a large amount of formaldehyde, because it is polymerized from formaldehyde2) phenolic plastics (PF) are condensed from phenols (mainly phenol) and aldehydes (mainly formaldehyde)3) urea formaldehyde foam is urea and formaldehyde as the main raw material, at a certain pH value, a certain temperature, the urea into Formaldehyde Solution in the synthesis of urea formaldehyde resin, also contains a large amount of formaldehyde4) also known as Vigny polyvinyl formal foam, nylon, also contains formaldehyde.5) melamine formaldehyde resin consists of melamine formaldehyde resin and filler, curing agent, pigment and other componentsIn addition, adhesives (composite flooring, composite cabinets) and paint (paint) which contains formaldehyde
There are many kinds of plastics. They are the general term for high polymer. Formaldehyde containing plastic usually has "aldehyde" in its name, or it has the word "formaldehyde" directly
Of course, there is to see whether formaldehyde exceeded the standard, but China's material safety factor is generally not high
