Method and device for the production of objects from foamed thermoplastic synthetic resins |
| abstract |
A double screw extruder embodies four working stages in the second of which the gaseous nucleating agent in the form of carbon dioxide, nitrogen, etc., is introduced under pressure into the extruder and dispersed in the plastic by the motion of the screw. The method is esp. used for foamed closed or open cell products with a cell size less than 0.2 mm. |
