The present invention relates to a method for producing a PUR/PIR foam body, comprising the steps of providing a mold adapted for applying an underpressure to the interior of the mold; introducing a reaction mixture comprising an isocyanate-reactive component A and an isocyanate B into the mold, and applying an underpressure to the interior of the mold, so the underpressure acts on the introduced reaction mixture. The underpressure is applied to the interior of the mold no later than the reaction mixture has started to set in the mold, and the isocyanate index of the reaction mixture is &#x2265;300.

Method for the vacuum-assisted production of a PUR/PIR foam body

The present invention is related to a method for the production of polyurethane foam, comprising the steps of:

Vacuum-supported method for the production of polyurethane foam

A cavity between inner and outer walls of an open-box-shaped mold is filled with a polyurethane reaction mixture, containing an isocyanate and an emulsion of an isocyanate-reactive composition with three polyols and a blowing agent, which is cured to a polyurethane containing polymer. The inner and outer wall are a fixed distance from one another and each wall comprises a bottom and sides. The mixture is fed through an inlet in the bottom of the outer wall. Before filling the cavity, the mold is turned downwards so that the mixture foams upwards, filling the cavity. The three polyols are polyether polyol obtained by adding an epoxy to carbohydrates or difunctional or higher-functional alcohols; polyether polyol obtained by adding an epoxy to an aromatic amine; and polyester polyether polyol obtained by adding an epoxy to the esterification product of an aromatic dicarboxylic acid derivative and a difunctional or higher-functional alcohol.

Insulation moulding and method for its manufacture

The present invention relates to a solar module comprising a first layer, a solar cell arranged above the first layer and a second layer arranged above the solar cell. The first and/or the second layer comprise a fiber composite material which comprises a preferably aliphatic polyurethane polymer 'dual cure' system) crosslinked thermally and by means of electromagnetic radiation. The material of the fibers of the fiber composite material is transparent at least in the region of visible light. The invention further relates to the use of this type of solar module and to a process for production thereof.
