Insulating product in particular heat-insulating product and method for making same

Insulating product based on mineral wool sized with a binder based on a phenol-formaldehyde resin, in which the binder comprises, as a mixture: 60 to 90 parts by weight of a phenol-formaldehyde resol having a free formaldehyde content of less than or equal to 25% by weight with respect to the dry we...

Beschreibung
Zusammenfassung:	Insulating product based on mineral wool sized with a binder based on a phenol-formaldehyde resin, in which the binder comprises, as a mixture: 60 to 90 parts by weight of a phenol-formaldehyde resol having a free formaldehyde content of less than or equal to 25% by weight with respect to the dry weight of resin and a free phenol content of less than or equal to 2.5% by weight with respect to the dry weight of resin, obtained by condensation in basic medium of phenol (P) and formaldehyde (F) in an F/P molar ratio of around 2.5 to 4 until the condensation product neutralized by sulphuric acid has a water dilutability of greater than 500% and less than or equal to 1500%; 10 to 40 parts by weight of urea. Use of such a sizing composition for manufacturing insulating products, while reducing the emissions of ammonia gas on the manufacturing line.
