A method is described for debonding a bonded article. The bonded article comprises at least two components which are bonded to one another by means of a polyurethane adhesive selected from aqueous polyurethane dispersion adhesives and polyurethane hotmelt adhesives. At least one of the components is a thermoplastic polyurethane. The components are debonded by treatment with an aqueous surfactant composition at elevated temperatures.

Process for recycling of bonded articles

A process for producing a molded article involves providing a thin-walled, gas-permeable shell; filling the shell with a foamed pelletized material composed of a polymer; and welding the foamed pelletized material to obtain the molded article. Molded articles are obtainable or obtained by such a process, and can be used as a footwear sole, part of a footwear sole, a mattress, a seat cushion, an underlay, a grip, a protective film, a component in automobile interiors and exteriors, a gymnastics mat, a body protector, a trim element in automobile construction, a sound insulator, a vibration damper, a cushion, a bicycle saddle, a toy, a tire or part of a tire, a covering for a track and field surface, a covering for a sports hall or a pathway, a damping layer or a damping core in a sandwich element, or a packaging.

Method for fusing particle foams by means of porous sleeves

A process for producing foam particles composed of thermoplastic elastomers having polyamide segments, comprising the steps:

A process for welding porous membranes, the process containing i) providing first and second porous membranes; ii) at least partially superimposing the first and second porous membranes to obtain an at least partial superimposition region; iii) welding the first and second porous membranes at least in a portion of the at least one superimposition region at a temperature in the range from 100 to 300&#xb0; C. to obtain an at least partially welded composite of the first and second porous membranes, wherein the first and second porous membranes are made of at least one thermoplastic elastomer selected from the group consisting of a polyurethane elastomer, a polyester elastomer, a polyetherester elastomer, a polyesterester elastomer, a polyamide elastomer, a polyetheramide elastomer, a polystyrene elastomer, and an ethylene-vinyl acetate elastomer, and wherein the first and second porous membranes have pores having an average pore diameter of less than 2000 nm.

Method for welding membranes

A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 &#x3bc;m, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 &#x3bc;m. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.
