Solar modules with a transparent polyurethane front side and a process for producing same

A process is described for producing foam materials from two-component reactive plastics using carbon dioxide as blowing agent by mixing at least one of the reactive components with carbon dioxide under pressure, mixing the components, at least one of which contains carbon dioxide under pressure, expanding the reactive mixture containing carbon dioxide obtained by mixing, and hardening, wherein the expansion takes place suddenly with the production of high rates of shear. Preferably the rate of flow of the reaction mixture is reduced after expansion.

A present invention relates to a process for preparing elastic, flexible slabstock foams by reacting polyisocyanates with at least one polyol having a molecular weight from 2,000 to 10,000, having a functionality of 2 to 4, which have at least two hydrogen atoms capable of reacting with said polyisocyanates; at least one polyol having a molecular weight from 400 to 4,000, having a functionality of 4 to 8 and having at least four hydrogen atoms capable of reacting with isocyanates; water and optionally, organic blowing agents; stabilizers; activators; additives and auxiliary agents; optionally, low molecular weight cross-linking agents with a molecular weight of 32 to 399; and liquid CO.sub.2, which is used as an additional blowing agent, and is decompressed in a decompression chamber containing fine-meshed gratings upstream of the discharge point to the conveyer belt.

Process for foam production using carbon dioxide dissolved under pressure

A method and device are described for the production of foams from two-component reactive mixtures using carbon dioxide as expanding agent, by mixing at least one of the reactive components with carbon dioxide under pressure. That mixture is then mixed with the other reactive component(s) to form a foamable reactive mixture, which is expanded and cured to form the final product. The foamable reactive mixture is expanded to ambient pressure through at least one fine-meshed screen (21a, 21b, 21c).

Method and device for the production of foam using carbon dioxide

A process and a device are described for the production of polyurethane foam by application of a froth onto the conveyor belt of a block-foam installation, whereby the froth is applied onto the lower conveyor belt in a free, substantially vertical fall and flowing of the froth contrary to the direction of movement of the conveyor belt is prevented by a stationary, substantially vertical barrier arranged transversely on the conveyor belt.

For the expansion of a liquid containing gas under pressure in dissolved form, it is proposed that the liquid be passed with expansion through an extended flow channel with a small cross-sectional measurement with generation of high rates of shear. The velocity of the liquid is then reduced prior to the foaming.
