PVC windows and TiO2
Titanium dioxide (TiO2) is a naturally occurring white pigment, which is also contained in PVC window profiles, for example, but in solid form. Only the dusty titanium dioxide is threatened with classification as a hazardous substance.
Due to possible health effects, TiO2 attracted attention in 2017 when it was proposed to classify the substance in powder form as a carcinogen. The decision on this is imminent.
We provide information on this current topic in an article in bauelemente bau no. 01/20, which looks at occupational health and safety and lists possible consequences of the classification for processors and recycling. The article can be found here (German).
