Abstract:
The invention relates to melamine/formaldehyde foam materials containing 80 to 98 wt % of an inorganic filler, wherein the wt % is based on the total weight of melamine/formaldehyde precondensate used for producing the foam material and inorganic filler.
Abstract:
The invention relates to a thermoformable melamine/formaldehyde foam containing 0.1 to 50 wt.% of at least one particulate filler material, said weight percentage being based on the total weight of a melamine/formaldehyde precondensate and the filler material used in the production of the foam. The at least one particulate filler material has a maximum melting point of 220 °C and an average particle diameter of 5 µm to 750 µm. The invention also relates to a method for producing the thermoformable melamine/formaldehyde foam and to the use of the melamine/formaldehyde foam for acoustic or thermal insulation in the field of automobile, ship, rail vehicle, and spacecraft construction, in the upholstery industry, or for insulating pipelines.
Abstract:
The invention relates to foams and molded parts made of foamed supporting materials that are selected from the group consisting of polyurethane resins, polyester resins, epoxides, as well as non-woven fabrics, woven materials, and open-cell two- and three-dimensional networks that consist of mineral, animal, plant, and chemical (natural/synthetic) fibers or mixtures thereof containing melamine/formaldehyde resin as a foaming reactive resins.
Abstract:
A plant substrate, consisting of (a) 25 to 100% by weight of an open cell melamine-formaldehyde foam, (b) 0 to 75% by weight of an additional synthetic plant substrate and/or mineral soil, and (c) 0 to 25% by weight of one or more active ingredient-releasing systems and/or additional additives, can be stored and transported in the completely anhydrous state and makes good air circulation in the soil possible.
Abstract:
The invention relates to an open-cell melamine resin foam, the surface of its cellular frame being totally or partially coated with a mixture of fluorocarbon resin and modified polyisocyanate. The invention also relates to a method for producing said foam and to the use thereof.
