Silicone shielding elastomers are a 30-durometer, electrically conductive, silver-Aluminium silicone shielding elastomer that is softer than many other EMI materials.
5752 – Silicone shielding elastomers are a 30-durometer (Shore A), electrically conductive, silicone shielding compound that is filled with silver-plated Aluminium particles and softer than many silver-Aluminium materials. 5752 – Silicone shielding elastomers combines EMI shielding with environmental sealing, and proves that metal-filled conductive silicones don’t have to be “too hard” for demanding applications.
The material is available in sheets of max. 380 x 500 mm and in the thickness: 0.81, 1.02, 1.57, 2.03, 2.63 mm.
Seal designers worry that a gasket made from a hard rubber will make an enclosure difficult to close, or allow the ingress of contaminants, chemicals, or water. Softer seal materials can improve compression, but it’s still essential to avoid metal-on-metal contact. To address customer requests and industry complaints about metal-filled elastomers, it is developed as an ultra-soft silicone with a true 30-durometer (Shore A).
5752 – Silicone shielding elastomers are supplied as fully-cured, conductive sheet stock; continuous extrusion profiles; or ready-to-mold compounds. Catalyzed raw materials are ready for press-cure molding and have a shelf life of six months. Uncatalyzed materials have an unlimited shelf life, but may require freshening after 1 to 2 years.
