摘要:
A method for producing an EMI/RF absorbing material including dispersing metallic flakes in a resin. The method also includes providing a first coat of the resin containing dispersed metallic flake to form a first layer. The method further includes providing a second coat of the resin containing dispersed metallic flake to the first layer to form a second layer. At least one of the first or second layers has a substantially uniform distribution of metallic flake throughout a thickness of the first or second layers.
摘要:
A diagonal bias-stretching device and a method of enhancing surface grain of imitation-leather material with such device, which device comprises a reciprocating roller moving between lateral positions on either side of a line of advance of an imitation-leather material, to provide for alternating diagonal stretching and relaxing of the material as it moves under tension in the line of advance.
摘要:
An EMI/RF absorbing film may comprise a polymer resin, and metallic flakes dispersed in the resin. A method for manufacturing an EMI/RF absorbing material. The method may include dispersing metallic flake in the polymer resin, applying the polymer resin and dispersed metallic flake on a releasable medium, curing the polymer resin to form a film, and releasing the cured polymer resin film from the release medium.
