| Abstract: |
| The rubber blowing extrusion is a new rubber process.It is useful for the production of wide and thin rubber sheets.The extruder used for this process features simple head structure，low price，less space and quality extrudate.The experiment is carried out on 3 types of extruder heads with different structures.The result shows that the appropriate blowing ratio of the extrudate is 2.0～2.5；the stretch applied on the sheet is in the longitudinal direction better than in the lateral direction during the blowing extrusion. |
