Abstract
A process and apparatus are described for the production of a flowable reaction mixture from at least two flowable reactive components which may be difficult to mix, which components react with one another to form a solid or a foam material. The components are injected into a mixing zone where they components are mixed in a continuous flow. The mixture flowing from the throttle zone is divided into two sub-streams which flow around a piston and which recombine opposite the division point.
