Abstract

A device for the batch reactive mixing and degassing of thermosetting polymers, such as polyurethane or similar, comprising at least one hermetically sealable container (1) in which the batch of thermosetting polymers is to be placed, a rotary plate (2) on which a satellite rotary plate is rotatably mounted, the container (1) being placed on said satellite rotary plate in order to cause said container (1) to rotate and to revolve, first means for driving the rotary plate (2) and second means for driving the satellite rotary plate, and means (3) for placing the container (1) under vacuum; said device is noteworthy in that it comprises means for controlling the first means for driving the rotary plate (2) providing a speed of revolution of the container (1) and a second means for driving the satellite rotary plate providing a speed of rotation of said container (1), said control means being capable of continuously varying the speed of revolution and the speed of rotation of the container (1) independently of one another. A process for the batch reactive mixing and degassing of thermosetting polymers.
