Abstract
The present invention relates generally to utilizing gasses for fragmenting polymeric materials and simultaneously modifying the surface area molecular structure of the said polymeric materials. More particularly, the present invention relates to a method and associated device for the processing of already preliminarily deformed polymeric materials, preferably without metal reinforcing elements, by utilizing aggressive gasses to both modify the polymeric materials surface area into an activated state and also simultaneously fragment the fed preliminarily deformed polymeric materials into a powder-like form with a relatively increased surface area.
