DEVICE FOR MAKING MICROPOROUS POLYMER MATERIALS |
| 摘要 |
Process is disclosed for producing water vapour permeable polymer sheets of improved surface smoothness. A coagulable polymer composition is applied to a dried evenly porous belt which then slides over a trough of non solvent which wets the belt so as to prevent the polymer composition passing right through the belt. |
