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 […]
Conductive Elastomer FAQs
A conductive elastomer is a specialized class of rubber-like materials engineered to conduct electricity while retaining the flexibility, resilience, and environmental resistance of conventional elastomers. These unique materials bridge the gap between electrical and mechanical performance, making them indispensable in applications where components must provide both sealing and electrical continuity. In fields such as aerospace, […]
