PROCESS FOR THE PRODUCTION OF A PHENOL-FORMALDEHYDE RESIN HAVING LOW FREE-FORMALDEHYDE CONTENT, THE PHENOL-FORMALDEHYDE RESIN RESULTING FROM THIS PROCESS, AND ITS USE AS A BINDER FOR MINERAL WOOL INSULATION PRODUCTS
The present invention relates to a method of reducing the content of free formaldehyde in phenol-formaldehyde resins, wherein this method comprises the step of treating the phenol-formaldehyde resin starting material with at least one oxidizing agent. The present invention further relates to the phenol-formaldehyde resin resulting from this process and its use as a binder in the manufacture of mineral wool insulation products of low formaldehyde emissions. The resulting phenol-formaldehyde resin has a free formaldehyde content of lower than 0.5 weight % determined according to ISO 11402; the pH is in the range of 7 to 10, the dilutability is more than 20 times in demineralized water at 20°C, the viscosity is below 100 mPa.s at 20°C, and the phenol-formaldehyde condensates, contained in the resin, consist of phenol and formaldehyde.

METHOD AND DEVICE FOR PRODUCING THERMOPLASTIC PLASTICS FOAM PANELS, PANEL MANUFACTURED USING SAME METHOD AND DEVICE AND PANELS' USE
A method for producing thermoplastic plastic foam panels (30) especially extruded polystyrene panels, comprises the steps of feeding foamable plastic material for forming a plastic melt to an extruder (11) and generating a plastic melt therein, and to a nozzle (12) which is positioned downstream from the extruder (11) directing the plastic melt into separate flow channels (16, 17) inside the nozzle (12) to form individual strands, expanding the individual strands to form strands (20a, 20b) of foamed plastic material at the outlet (32) of the nozzle (12), combining, preferably under pressure, the co-extruded strands (20a, 20b) of foamed plastic material at their main surfaces (50) to form a joined strand (22) of foamed plastic material; and cutting the joined strand (22) of foamed plastic material into pieces of defined length to form the panels (30). Further, the invention relates to a device for carrying out the method and a panel as produced by such method and device, and the use of such panel for insulation purposes.
