This invention relates to the preparation of granular, filled compositions based on amino-formaldehyde resins in a screw installation. The invention makes it possible to increase the manufacturability of a granulated composition in a screw unit, as a result of which the duration of the stable operation of the unit before driving the nozzles on the granulating head is increased to 10 hours (known for 0.5 hours), due to the use of a composition comprising parts by weight respectively: melamine formaldehyde resin 42-55, a filler selected from the group: glass powder, glass roving, talc, asbestos, kaolin, cellulose or their mixture, 43-56, lubricant 0.5-1.5 and powdered polyethylene with a particle size of 0.5 -200 µm, 0.2-1. 2 tab. |
