摘要:
A double-sidedly bondable planar element which has an electrical contacting layer via which it is self-regulatingly intrinsically heatable and at the same time has a high flexibility. The particular features of this planar element are that the planar element in the storage condition is adhesive on one side only, and is therefore particularly easy to handle, and that, on bonding, the adhesive passes through cutouts in the contacting layer, and the planar element thus becomes double-sidedly bondable. The invention further provides a method for the bonding of this planar element, including as a key step the passage of the adhesive through the cutouts in the contacting layer, thus turning a single-sidedly adhesive planar element into a double-sidedly adhesive planar element.

A heating element including a current conductor through which electric power is conducted and electricity converted into heat by a voltage drop across an ohmic resistor. The heating element is a planar or a strip-shaped structure and is provided with at least one support layer and an adhesive layer, while the current conductor is designed as an additional, current-conducting layer which is arranged between the support layer and the adhesive layer. The support layer, the current-conducting layer, and the adhesive layer are transparent.

A heat conduction composition is proposed, comprising at least one polymer and a heat-conducting auxiliary material that has an especially high heat conductivity and at the same time has a high mechanical strength. To this end, the heat-conducting auxiliary material comprises particles that in turn are made up of primary particles and that have a mass-specific surface area of 1.3 m2/g or less. Also described are a heat-conducting surface element manufactured from said heat conduction composition as well as application possibilities thereof.

摘要:
A heat-activatedly bondable sheetlike element having at least one electrically conductive sheetlike structure and at least two layers of different heat-activable adhesives. A first heat-activatable adhesive layer is located substantially on a first side of the electrically conductive sheetlike structure and the second heat-activatable adhesive layer is located substantially on a second side of the electrically conductive sheetlike structure. Activation temperatures for achieving the adhesive properties of the heat-activatable adhesive layers differ from one another less than the melting temperatures of the two heat-activatable adhesive layers.
摘要:
A method glues a heat-activated glueable surface element to an adhesive substrate which does not conduct electric current, whereby a surface thereof has only a low thermal conductivity. The heat-activated glueable surface element has an electrically conductive layer in addition to a heat-activated adhesive mass. The layer is inductively heated for a short time in an alternating magnetic field at a frequency from a middle frequency range. A high pressure of at least 1 MPa is exerted on the gluing surface simultaneously to the inductive heating, whereby preventing thermal decomposition reactions is possible. Further, a device performs the method and has an induction heater integrated in a press tool.
摘要:
A novel, transparent, non-substrate-based permeation barrier film for encapsulating electronic, more particularly optoelectronic, assemblies consists of a first polymer layer (10), a first inorganic barrier layer (20), at least one at least partially organic compensation layer (30), at least one further inorganic barrier layer (21) and also at least one further polymer layer (11), wherein the polymer layers and the inorganic barrier layers, respectively, can be made of the same or different material, wherein the inorganic barrier layers have a thickness of between 2 and 1000 nm, and wherein the polymer layers and the at least partially organic compensation layer have a thickness of less than 5 [mu]m, preferably between 0.5 and 4 [mu]m. The film can have, on one or both sides, an auxiliary carrier attached by means of a re-releasable adhesive. It is also possible for a plurality of films to be laminated to one another by means of a further at least partially organic compensation layer.
