Abstract
The invention relates to a composition for the production of foams based on phenolic resin, use thereof, and a process for the production of the composition. For provision of a composition for the production of foams based on phenolic resin, where the said composition delivers improved reaction to fire with, in essence, no alteration of further important foam properties, it is proposed that the composition comprises an alkoxylated novolak, wherein the novolak is produced using phenol, cresol and/or xylenol.
Claims16
A phenolic resin composition for the production of foams, the composition comprising:
- at least one phenolic resole;
- and
- at least one alkoxylated novolak, wherein the alkoxylated novolak is produced using phenol, cresol, xylenol, or combinations thereof, and wherein the alkoxylated novolak has a number average molecular weight (Mn) of 200 g/mol to 3,000 g/mol.
