CONTINUOUS METHOD FOR PRODUCING SOLID, HOLLOW OR OPEN PROFILES |
摘要 |
Disclosed herein is a method for producing a polystyrene foam. The polystyrene is dosed with a gas and the polystyrene and gas are mixed in an extruder in order to obtain a homogenous mixture. The homogeneous mixture is cooled as it travels through the extruder and is then extruded from the die at a pressure of less than 7 MPa to form a foam with a smooth skin. |
