Method for lowering the formaldehyde emissions of melamine/formaldehyde polymer moldings, films or fibers by impregnating the melamine/formaldehyde polymer moldings, films or fibers with an aqueous solution of at least one formaldehyde scavenger.

Melamine formaldehyde foam with reduced formaldehyde emission

Melamine-formaldehyde foam with improved weather resistance comprising 0.1 to 8 wt.-% of at least one UV stabilizer, such as benzotriazole derivatives and piperidinol derivatives and further 1 to 3 wt.-% of at least one hydrophobicization agent, such as organo-modified siloxanes and silanes and processes for producing such melamine-formaldehyde foams with improved weather resistance.

Melamine-formaldehyde foam with improved weather resistance

A process for producing a melamine-formaldehyde foam by heating and foaming an aqueous mixture M using microwave radiation, said mixture M comprising at least one melamine-formal-dehyde precondensate, at least one curative, at least one surfactant, at least one blowing agent and at least one linear polymer with a number average molecular weight Min the range from 500 to 10,000 g/mol and at least two functional groups selected from OH, NHor COOH as well as a melamine-formaldehyde foam obtainable by this process and its use.

Production of melamine-formaldehyde foams

A melamine/formaldehyde foam having an open-cell foam structure, with an impregnation applied to the foam structure that comprises at least one particulate phyllosilicate surface-modified with aminosilane and at least one anionically- and/or nonionically-stabilized polyurethane dispersion.
