Abstract: A novel method of producing an encapsulated light emitting device. A preferred mold release film that can be used during the encapsulation of a LED chip has an elastic modulus and a glass transition temperature that are low enough as compared to the desired molding temperature that the release film will closely conform to the interior of the molding cavities used to form a protective lens surrounding an LED chip. A preferred release film according to embodiments of the present invention comprises a fully fluorinated polymer, such as a perfluoroalkoxy polymer, including MFA, or fluorinated ethylene propylene.

Abstract: A composite material includes a non-polar polymer and alumina hydrate particulate. The composite material has a Heat Distortion Performance of at least about 10% relative to the non-polar polymer absent the alumina hydrate particulate. The composite material may include a coupling agent including a phosphinic acid group, a phosphonic acid group or an ester derivative thereof.

Abstract: A release liner can include one or more release layers. The release layer can include a thermoplastic polymer matrix. Moreover, the release layer can include an organic particulate phase. The organic particulate phase can be dispersed in the thermoplastic polymer matrix. In one embodiment, the organic particulate can include micronized PTFE particles. The PTFE particles can be present in the release liner such that the surface roughness Sa of the release liner ranges from 0.1 microns to 1 micron.

Abstract: A composition includes a) a melt processable polymer including at least one chemical moiety having a partial charge; and b) a nucleating agent having a surface charge that is opposite the partial charge of the chemical moiety of the polymer, wherein the nucleating agent accelerates the rate of crystallization of the melt processable polymer; wherein the nucleating agent has a melting point greater than the melting point of the melt processable polymer. In an embodiment, a method of making the composition is also provided.

Abstract: The invention describes a multi-layered film comprising a modified fluoropolymer and a silicone material. The laminate is useful to protect a photovoltaic cell, for example, as an encapsulant.

Abstract: The invention describes a carbon black particulate filled film, useful as a backsheet for a photovoltaic construct.

Abstract: The invention describes a fluoropolymer laminate that includes a first substrate that can be a modified fluoropolymer having polar functionality and a second substrate. The substrates are laminated at an elevated temperature suitable for lamination to occur and then are subsequently treated with radiation, such as ultraviolet radiation, gamma radiation and/or electron beam.
