5752 Silicone shielding elastomer

Silicone shielding elastomers 5752

Silicone shielding elastomers is a 30-durometer, electrically-conductive, silver-aluminum silicone shielding elastomer that’s softer than many other EMI materials.

5752 - Silicone shielding elastomers

5752 - Silicone shielding elastomers is a 30-durometer (Shore A), electrically-conductive, silicone shielding compound that’s filled with silver-plated aluminum particles and softer than many silver-aluminum 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.

More Compression, Better Sealing

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 a ultra-soft silicone with a true 30-duromter (Shore A).

Ultra-Soft Silver-Aluminum Silicone

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 indefinite shelf life, but may require freshening after 1 to 2 years.
