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 method for cleaning medical equipment by scrubbing the equipment with an open-cell melamine-formaldehyde foam comprising an antibacterial active composition, and wherein the open-cell melamine-formaldehyde foam is prepared from a melamine-formaldehyde precondensate, wherein the molar ratio melamine to formaldehyde of the melamine-formaldehyde precondensate is smaller than 0.5.

Method for cleaning medical equipment

Described herein is a process for preparing a foam (FA) with a Poisson's ratio in the range of from &#x2212;0.5 to 0.3, the method including the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming including triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). Also described herein is the foam obtained or obtainable according to the process and the use of the foam as, for example, an energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.

Auxetic polyurethane and melamine foams by triaxial compression

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.

Phyllosilicate-impregnated melamine-formaldehyde foam

The present invention relates to a method for the production of crude oil from subterranean, oil-bearing formations comprising at least the following steps of providing an aqueous surfactant composition comprising water and a surfactant mixture, injecting said surfactant composition into the subterranean, oil-bearing formation through at least one injection well, thereby reducing the crude oil-water interfacial tension to less than 0.1 mN/m, and withdrawing crude oil from the formation through at least one production well, wherein the surfactant mixture comprises at least a surfactant (A) having the general formula R&#x2014;O&#x2014;(CHCH(R)O)&#x2014;(CHCH(CH)O)&#x2014;(CHCHO)&#x2014;R&#x2014;YM(I) and a solubility enhancer (B) having the general formula R&#x2014;O&#x2014;(CHCH(CH)O)&#x2014;(CHCHO)&#x2014;R&#x2014;YM(II), wherein Rto R, a, b, c, x, y, Y and M have the meaning as defined the the description and claims. The invention further relates to said aqueous surfactant composition and methods for preparing the same as well as the use of solubility enhancer (B) for enhancing the solubility of anionic surfactant (A).
