Glass microspheres
Tempered sodium glass microspheres are highly resistant to wear and impact. They are used in shot blasting cleaning machines for surface cleaning of the articles to be treated, where cleaning is required while avoiding any alteration of the articles. Glass microspheres are chemically inert and do not contain lead or sulphides I their free state.
Standard types including chemical-physical analysis are as shown in the table below.
