Abstract:
The present invention relates to an adhesive, comprising at least one polymer system obtained by a process for reducing the melt viscosity of at least one polymer blend starting material, wherein the process comprises the step of treating at least one polymer blend with at least one radical donor under shear stress at a temperature above the softening point of said polymer blend.
Abstract:
A method for performing a phase transition, in particular a melting process, by heating a carrier medium containing or constituting a phase change material in a reactor, the carrier medium being brought into contact with a solid heating medium that can be heated by electromagnetic induction and that is contained in the reactor and is surrounded by the carrier medium, and heating the heating medium by electromagnetic induction by means of an inductor, the phase change material undergoing a phase transition and the carrier medium being separated from the heating medium after the phase transition. This preferably takes place in a continuous-flow reactor. The inductor preferably generates an alternating field having a frequency in the range from 1 to 100 kHz.
Abstract:
The invention relates to crosslinking compositions for polyurethane elastomers, made up of a polyol component containing: 30 to 80 wt % polyether diols and/or polyester diols; 10 to 40 wt % polyols comprising at least three OH groups; and to 50 wt % of a monofunctional compound that comprises an isocyanate-reactive group, and an isocyanate component containing an at least trifunctional isocyanate, such that the NCO/OH ratio is intended to be between 0.9 to 1.2. Use of the corresponding crosslinked polyurethane elastomers as molded elements is also described.
Abstract:
