AWUKO uses paper backing in all thicknesses and tearing strengths, as well as cotton and polyester fibres whose structure and flexibility are perfectly matched to the requirements of most different sanding processes.
All abrasive grains used at AWUKO are synthetically produced in high-temperature vessels and, by crushing and screening processes, cassified into grain size Groups ranging from very coarse to superfine. All grains used at AWUKO conform to the FEPA standard. The field of application determines the type of grain that is electrostatically applied on the base, i.e. grains made of corundum (aluminium oxide), zirconia alumina, and silicon carbide come into use. The grain coating varies from dense to open.
