Plastic shielding materials are flame
retardant
Chomerics has further enhanced its range of innovative Premier conductive plastic shielding materials with the introduction of nonhalogenated flame retardant grades.
Chomerics has further enhanced its range of innovative Premier conductive plastic shielding materials with the introduction of nonhalogenated flame retardant grades Rated to UL94V0, the new materials are available with three different levels of shielding performance enabling engineers to choose the material that accurately matches the shielding and mechanical requirements of their application, so avoiding overdesign and unnecessary cost

The latest thermally conductive adhesive tape from Chomerics can significantly simplify PCB assembly by eliminating thermal grease and mechanical fasteners.
Ceramic heat spreaders replace heatsinks
Designed for EMI-sensitive applications, the latest low-profile heat spreaders from Chomerics provide a simple and effective method of cooling semiconductors.
Premier shields give weight, cost and space savings as well as greater design freedom and improved strength compared with most other existing shielding applications and approaches.
Designs with wall thicknesses down to 0.8mm can be achieved using the abrasion and corrosion resistant materials.
By having its shielding functionality integrated, the need for costly supplementary processes such as plating and painting are alleviated.
The ability to include design features such as internal compartments means that a single Premier part can accommodate multiple logic and RF components in a single shield.
This helps to further reduce cost and eases assembly.
Flame retardant versions of Premier are suitable for continuous use at 70C with excursions to 85C.
Existing non-flame-retardant variants are available with a continuous operating temperature range of up to 105C to provide a solution for extremely thermally demanding applications.
Flame retardant versions of Premier are available in a choice of three compounds that give increasing levels of shielding performance.
Basic performance is given by A220-FR, A230-FR delivers intermediate shielding, and A240-FR offers up to 85dB attenuation.
The mechanical performance of the various materials is also different, with higher shielding performance versions being more rigid than lower attenuation grades.
