Case Study: Replacing a Competitor’s EMI Gasket Material
Specialty Silicone Products makes offsets, or alternatives, to CHO-SEAL materials from Parker Chomerics. For example, SSP2486-70 is our 70-durometer (Shore A) silver-aluminum fluorosilcone that can be used instead of CHO-SEAL 1298. Like many of our EMI elastomers, SSP2486-70 is part of the M83528 Qualified Product List (QPL) from the Defense Logistics Agency (DLA). Recently, a […]
EMI Shielding: A Practical Guide for Reliable Electronics
SSP makes EMI shielding materials and products (i.e. EMI gaskets and EMI O-rings) from electrically conductive silicones that we make in Ballston Spa, New York (USA). This article is a basic but practical guide for engineers who need to design reliable electronics. Introduction Electromagnetic interference (EMI) is a critical concern in modern electronics, especially as […]
EMI Connector Gasket FAQ
Specialty Silicone Products (SSP) makes EMI connector gaskets that reduce or eliminate the transmission of electromagnetic interference (EMI) between connected devices, or through the connector itself. We mold and fabricate standard and custom products from the EMI elastomers that we make at our Ballston Spa, New York (USA) manufacturing facility. Many of SSP’s EMI elastomers […]
EMI Gasket Fabrication without Tooling
What’s the fastest way to fabricate a flat EMI gasket? Die cutting is quick and efficient at higher volumes, but there’s tooling to wait for. If you need low to medium volumes instead, have you considered flash cutting? This computer-controlled cutting process uses standard knives instead of specialized tools and is one of several EMI […]
Cold Spliced EMI O-Rings vs. Vulcanized EMI O-Rings
Compare cold spliced EMI O-Rings with vulcanized EMI O-rings and make the right choice for your EMI shielding project. Ask SSP for EMI O-rings. Specialty Silicone Products (SSP) extrudes EMI elastomers into solid cords that come in various stock sizes. Die cutters and other gasket fabricators can convert these cords into bonded O-rings that provide […]
EMI Shielding Comparison
Use the tables below for an EMI shielding comparison with electrically conductive silicones. EMI/RFI elastomers are shielding materials that combine the advantages of rubber with the electrical properties of metals. An inert, synthetic elastomer, silicone offers thermal stability over a wide temperature range along with resistance to ozone, water, and sunlight. When filled with tiny […]
EMI O-Ring Applications
EMI O ring applications solve the continuity issues in removable parts in an enclosure. They also seal gaps and improve enclosure reliability. EMI O-Ring Applications: Understanding the Basics What is EMI? Electromagnetic interference (EMI) occurs when external electromagnetic energy mixes with another electronic system and then disturbs the system’s original flow. EMI is one of […]
RFI Shielding Materials vs. EMI Shielding Materials
What’s the difference between RFI shielding materials and EMI shielding materials? This article explains. SSP’s electrically conductive elastomers are used for both RFI shielding and EMI shielding, so contact us to discuss your shielding application. RFI vs. EMI: Understanding the Differences Electromagnetic interference (EMI) and radio frequency interference (RFI) are often mentioned together in engineering […]
Does a Conductive Elastomer Gasket Provide EMI Shielding?
Does a conductive elastomer gasket provide EMI shielding? The short answer is yes, but some conductive elastomers provide ESD protection instead. What is a Conductive Elastomer Gasket? A conductive elastomer gasket is made of a rubber material that contains specialized fillers. Normally, elastomers are electrically insulating rather than electrically conductive. That means they prevent rather […]
