This material does not contain any fillers that release harmful dust during maching. Nevertheless the dust content<br />
3<br />
in the air should not rise above 6 mg/m . Safety procedures recommended by the vocational co-operative of the<br />
chemical industry should be complied with. The article is not a regulatory product according to ICC regulations.<br />
In accordance with general local and national regulations waste is to be disposed by incineration in authorized<br />
places or conveyed to authorized tips (EAK 120105).<br />
Technical statements and recommendations refer to current standard of technique and are based on our own<br />
experience. Further developments and improvements are reserved. Due to the variety of proccessing possibilities<br />
own experiments are recommended to optimize results.
