PVC wallpaper is made of Polyvinyl chloride. The PVC is not toxic, and it will not do harm to human health if contact with the human body. The only condition PVC produces harmful fumes is when it's exposed to 100 degrees for a long time.
1. Vinyl chloride monomer
Vinyl chloride monomer (VCM) for polymerizing PVC is carcinogenic. So the government usually stipulate that when the amount of VCM is less than 1PPM(parts per million), PVC is a non-toxic and sanitary.
2. The impact of vinyl chloride monomer
The coating of wallpaper is a polymer. Under normal circumstances, the chlorine it contains will not have any effect on the human body. Only in a high temperature state, chlorine will be free, resulting in excessive chlorine content.
3. Heavy metals in pigments
Water-based pigment, using water as diluent, has no effect on the environment or human health. However, the use of oil-based pigment with ethyl acetate as diluent, will cause pollution to the environment. Unlawful manufacturers even use bad oil-based pigment, the content of heavy metal such as lead is over the standard, which will be harmful to human nerves, internal organs and skin.
1. Check whether the PVC is sanitary.
2. Check the material testing certification. PVC processing uses a large number of additives, especially stabilizers. PVC wallpaper which meets the standard is non-toxic, so when you buy it, pay attention to choose the wallpaer has been tested and certified.
