摘要:
Polymer compositions containing a polyoxymethylene polymer are disclosed that are receptive to paints and ink coatings. The polymer composition contains a polyoxymethylene polymer having a relatively high terminal hydroxyl group content in combination with a thermoplastic elastomer. In one embodiment, a coupling agent may be added for coupling the thermoplastic elastomer to the polyoxymethylene polymer. The polymer composition can be molded into various articles and then painted or printed with an ink composition. The polymer composition has been found to dramatically improve adhesion between the molded article and the ink or paint coating.

Fluid activatable, multilayer adhesive compositions for use with liner-free labels, and methods of making and using thereof are described herein. The compositions contain a functional layer, such as an adhesive layer, which is applied to the label and a barrier layer which is applied on top of the adhesive layer. The multilayer composition prevents the adhesive layer on the label from interacting with the face of an adjacent label, particularly when the labels are stored as coils or folded stacks.

A composition includes polymer and dispersed infrared-reflective clusters of titanium dioxide primary particles. The titanium dioxide primary particles are cemented together with precipitated silica and/or alumina to form clusters. The titanium dioxide primary particles have an average particle diameter in the range of from about 0.15 to about 0.35 micron, while the clusters of titanium dioxide primary particles have an average cluster diameter in the range of from about 0.38 to about 5 microns and a geometric standard deviation (GSD) in the range of from about 1.55 to about 2.5.

Cushioning elements include a porous foam comprising a series of interconnected cell walls and an elastomeric material formed over at least a portion of the interconnected cell walls. The porous foam is configured to allow gases to pass through at least a portion thereof. Methods of forming cushioning elements may include coating interconnected cell walls of a breathable porous foam with a liquid comprising an elastomeric material, solidifying at least a portion of the elastomeric material, and providing a gas path through the elastomeric material. Other methods include pressing sheets of foam together at a pinch point, disposing a liquid between the foam over the pinch point, coating the foam with the liquid, and separating the sheets beyond the pinch point. Some methods include consolidating a plurality of portions of porous foam into a continuous cushioning material.
摘要:
Die vorliegende Erfindung betrifft ein Schichtsystem, umfassend eine Schicht aus parallel zueinander ausgerichteten Kohlenstoffnanoröhren und eine unmittelbar damit verbundene Deckschicht mit metallischen Eigenschaften, aus der die Kohlenstoffnanoröhren im "tip"- Wachstum gewachsen sind. Das Schichtsystem kann weiterhin eine Basisschicht und/oder ein Substrat aufweisen. Es ist erhältlich durch das Erzeugen einer strukturierten Schicht aus einer ersten Phase, die aus einem Metall besteht, das keine eigenständige katalytische Aktivität hinsichtlich des Entstehens von CNTs aus der Gasphase aufweist, sowie einer zweiten Phase aus einem Metall, das die Entstehung von CNTs aus der Gasphase katalysiert, auf einem Substrat oder einer Basisschicht, wobei die erste Phase eine ungleichmäßig dicke und/oder gefaltete, gegebenenfalls mit Poren durchsetzte Struktur besitzt und die zweite Phase sich in Vertiefungen und/oder Poren der ersten Phase befindet derart, dass beide Materialphasen in der lateralen Ebene zumindest teilweise nebeneinander vorliegen, auf dem Substrat bzw. der darauf befindlichen Basisschicht. Auf dieser strukturierten Schicht wird Kohlenstoff aus einer kohlenwasserstoffhaltigen Gasatmosphäre abgeschieden, wobei sich Kohlenstoffnanoröhren bilden, die zumindest Teile der strukturierten Schicht in geschlossener Form anheben. Das Substrat oder die Basisschicht kann anschließend entfernt werden. Das Schichtsystem der Erfindung eignet sich zur Anwendung in einer Vielzahl von Bauelementen und elektronischen Mikro- und Nanosystemen, Flip-Chip-Verbindungen, Sensoren oder Aktoren, insbesondere von Drucksensoren, Berührungssensoren, optischen Sensoren, Spiegeln, Projektoren, optischen Filtern, Nanopositioniersystemen oder Interferometern, in einer spezifischen Form auch in einer Superkapazität.
摘要:
The present invention relates to a heat dissipating tape using a conductive fiber and a method for manufacturing same. More particularly, the present invention relates to a heat dissipating tape comprising a heat dissipating adhesion portion having as a conductive base material portion, a conductive fiber coated with a conductive substance, and having a heat dissipating adhesive coated on the conductive base material portion, the heat dissipating adhesive being an acryl adhesive or a silicone adhesive containing graphite. The heat dissipating tape of the present invention has an excellent resistance to external forces on the product, has an excellent outer appearance due to the smooth surface, is less likely to get damaged, and enables the delamination of the conductive base material portion and the heat dissipating adhesion portion to not occur as easily.
