ABSTRACT:
In devices for the production of a reaction mixture, which forms a foamed plastic, from at least two reaction components and a foaming agent, it is possible to determine the content of foaming agent in a reaction component mixed therewith in that an intermediate container is provided for this mixture. The intermediate container is provided with a circulating line in which are arranged a circulating pump and a temperature-compensating viscometer. Optionally, the foaming agent content can be automatically adjusted to the theoretical value via a computer and pulse lines by influencing the drive means of the dosing pumps for the respective reaction component and the foaming agent.
