Abstract: Thermal cleaning of articles that come into contact with polymer dispersions comprises treatment in a sand fluidised bed at a temperature high enough to pyrolyse and/or vaporise the contaminants produced by the polymer dispersions. Also claimed is the use of a sand fluidised bed for cleaning these articles.
