Use of melamine resin fibers and insulating materials based on melamine resin fibers and polyalkylene terephthalate fibers

The invention relates to a continuous process for preparing aminoplastics and/or phenolics, in which a precondensate solution is prepared in a first extruder ( ), the precondensate solution is continuously fed, with addition of additives, to a second extruder ( ) with partial filling in the feed section (E) and devolatilization section (G), devolatilized in the second extruder ( ) and then formed to give a molding composition or an end product. The process is particularly suitable for preparing melamine resins, in particular melamine-formaldehyde resins, as well as for preparing urea-formaldehyde resins.

Continuous method for producing amino- and/or phenoplasts

The present invention relates to flameproof fabrics based on melarnine resin fibres, fireproof blankets and clothing made therewith and their use for extinguishing fires and protecting people and objects from fire, combustion products and/or extinguishing agents.

Metal coated melamine resin fiber and natural fiber mixture

Fiber blend

A process for producing fibers by spinning a resin by a centrifugal spinning process comprises supplying a resin solution having a viscosity from 50 to 200 Pa.s at the spinning temperature to a whirler plate and ensuring that the resin solution is under a sufficient pressure to completely fill the nozzles of the whirler plate as the fibers are being spun. The process is particularly suitable for producing fibers based on amino resins. In the apparatus the supply line for the resin is preferably located within the driveshaft.

Production of fibers by centrifugal spinning

A thermally stable electrical insulating material comprises melamine resin fibers and a polymer fibril binder with or without a synthetic resin powder and mineral fillers.

Moldings, in particular foams and fibers, based on melamine/formaldehyde condensation products, in which from 0.1 to 70 mol% of the melamine have been replaced by melamine substituted by from 1 to 3 hydroxyoxaalkyl groups of the formula

The continuous preparation of melamine/formaldehyde precondensate solutions is carried out by a process in which melamine, formaldehyde and, if required, modifiers and/or additives are metered into a continuous mixer, and the homogeneous mixture is passed into a single-screw or twin-screw extruder, condensed at elevated temperatures, cooled and extruded.

Manufacture of fibrids from polymers

A process for the manufacture of thermoplastics fibrids, in which a solution of the thermoplastics material is fed to an impulse exchange chamber, where it is cooled so as to cause precipitation of the thermoplastics material, while it is subjected to a field of turbulent shear forces caused by the introduction of a gaseous or liquid medium into the said impulse exchange chamber.
