Abstract:
A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.
Abstract:
A heat generation system and a method of curing an adhesive for an electrical generator rotor during a rotor rewind operation are provided. The heat generation system includes a heating source in contact with a pole of the electrical generator rotor to heat the pole, thereby reducing heat loss from the adhesive to the pole. The heat generation system also includes at least one holding arrangement holding the heating source in contact with the at least one pole. The method includes applying an adhesive onto an electrical generator rotor and utilizing a heat generation system to provide heat to the electrical generator rotor. The method further includes placing a heating source in contact with the pole, holding the heating source in contact with the pole using a holding arrangement, heating the pole by activating the heating source, and heat curing the adhesive.
Abstract:
A mixture of an elastomer, carbon black, and inorganic fillers provides a highly useful laser-ablatable flexographic printing plate precursor formulation. This formulation is sensitive to infrared radiation. Both flexographic printing plates and printing sleeves can be made using the mixture.
Abstract:
Domain segregation of polymer blends or block copolymers in the presence of thermal conducting high aspect ratio nanocrystals leads to preferential placement of conductive filler either inside one domain, which promote the self-assembly of a thermal and/or electrical conducting pathway composed of high aspect ratio filler. The self-assembly of such thermal and/or electrical conducting pathway effectively enhances the thermal and/or electrical conductivity of the composite with significantly less amount of filler.
