Military Gaskets for EMI Shielding: What are MIL-DTL-83528 and QPL 83528?
Designers of military gaskets face application-specific challenges. For example, not all EMI shielding elastomers that meet MIL-DTL-83528 requirements are QPL listed. For gasket fabricators who support military applications, it’s important to know what MIL-DTL-83528 is and how it’s related to the QPL. It’s also worth learning about some other conductive shielding elastomers that are used […]

Silicone Gasket for EMI Shielding
Do you need a silicone gasket for EMI shielding? Among its advantages, silicone rubber is flexible, weather-resistant, and can withstand a wide range of temperatures. Silicones for custom rubber gaskets are also available in lower (softer) durometers, even when they contain electrically contain fillers such as silver-coated or nickel-graphite particles. Composites and Costs A silicone […]
Custom Rubber Gaskets for EMI Shielding
Custom rubber gaskets for EMI shielding combine shielding against electromagnetic interference (EMI) with environmental sealing. These EMI gaskets are fabricated from specialized materials that consist of a base elastomer and an electrically conductive filler. Base elastomers include silicone, fluorosilicone, and EPDM. Fillers include silver-coated and nickel-graphite particles. During material selection, engineers need to balance EMI […]
Chomerics EMI Gasket Alternatives from SSP
Specialty Silicone Products (SSP) makes EMI gasket materials that you can use as alternatives to CHO-SEAL® materials from Parker Hannifin. The table shows when SPP products are offsets.
EMI Material Types
EMI material types fall into two main functional categories: reflective (conductive) and absorptive (lossy). There are many specialized formulations depending on the environment, frequency range, and mechanical requirements. Methods of classification include composition, mechanism of action, and form factor, but engineers generally choose from among the following. Conductive elastomers Conductive foams and fabrics Metal-based materials […]

Conductive Silicone Rubber Manufacturer
Conductive silicone rubber is a special type of silicone material that can conduct electricity. Normally, silicone is an electrical insulator, meaning that it doesn’t let electricity flow through it. When silicone is mixed with electrically conductive particles, however, the resulting compound becomes able to carry electrical current based on its properties. How is Conductive Silicone […]
EMI Gasket Manufacturers: How They Differ
EMI gasket manufacturers can fabricate a range of products from electrically conductive silicones. That’s important since different challenges with environmental sealing and EMI shielding require different solutions. For example, industrial robots require molded or bonded EMI O-rings that fit into a groove. Enclosures may require flat EMI gaskets that are die-cut or flash-cut instead. There […]
Silver Prices and EMI Shielding Costs: What You Need to Know
Silver Prices and EMI Shielding Costs: What You Need to Know Last week, the price of silver hit a record high of $54.47 USD per troy ounce. That’s good news if you’re a silver investor but concerning if you buy silver-filled elastomers for EMI gaskets or EMI O-rings. If current trends continue, the high price […]
