3B Certified Silicones with High Flex-Fatigue Resistance

SSP supplies silicones with high flex-fatigue resistance, a measure of a material's ability to withstand repeated flexing or bending without cracking. These silicones pass the DeMattia Flex Resistance Test and meet the full requirements of the A-A-59588 3B specification – with no exceptions for flexural testing.

Bonded EMI O-rings for Reduced Cost and Improved Performance

Bonded EMI O-rings from SSP use tooling that's faster and less expensive to produce. Because we build the tools and extrude the EMI cords in-house, we can supply you with more prototypes than if you'd waited for a single molded one. The bonding method that we use also reduces the risk of EMI leakage.

EMI O-rings for Industrial Automation

For industrial automation companies that need EMI O-rings, SSP provides both molded and bonded solutions. Molded EMI O-rings are produced as one-piece gaskets. Bonded EMI O-rings use tooling that's faster and less expensive to produce.

EMI Shielding for Electric Vehicles

By their very nature, EVs place a large amount of electrical and electronic content into confined spaces. The radiated and conducted emissions from these systems can disrupt circuits and result in conditions that range from minor inconveniences to dangerous losses of vehicle function. There are sources of EMI outside of the vehicle as well.

Extruded EMI Elastomers

SSP extrudes EMI elastomers in both standard and custom profiles. These extrusions can have very thick or very thin cross-sections and can be solid or hollow. Choose from channels, cords, half-rounds, P-shapes, rectangles, and U-shapes with silicone or fluorosilicone as the base elastomer.

Fluorosilicones for Environmental Sealing and EMI Shielding

Fluorosilicones combine the high and low-temperature resistance of silicones with the fuel and oil resistance of fluorocarbons. Compounds that are filled with metal or metal-coated particles also provide electrical conductivity and EMI shielding.

Frame Gaskets for EMI Shielding: How Molding Reduces Costs, Increases Yields, and Supports Low-Volume Production

SSP supplies mold-able EMI silicones. For frame gaskets, molding minimizes material waste, maximizes material yields, and eliminates the need to bond cut lengths. Fabrication processes like die cutting are efficient, but the cut-out section of a frame gasket can represent significant material waste.

How to Choose Particle-Filled Silicones to Meet Multiple Design Requirements

The EMI shielding that's used in automotive, aerospace, and medical electronics must meet multiple design requirements. For example, an EMI gasket that's used with aircraft may need to resist the splash of jet fuel. Shielding that's used with EV charging stations may require compliance with UL 94 standards for flammability.

Nickel-Aluminum Silicone for Corrosion-Resistant EMI Gaskets

Nickel-aluminum-filled silicones exhibit the lowest amount of flange pitting from galvanic corrosion, an electrochemical process that occurs when two different metals are in contact in a saltwater environment. These shielding silicones also exhibit excellent galvanic stability with aluminum flanges.

Silicone Prices and Silicone Specifications

Silicone prices are higher than before, but buyers need to consider the true costs of meeting silicone specifications - and what can happen if you choose a cheaper compound. If a supplier changes a formula, the material may no longer meet a qualification specification.

USP Class VI Silicones for Medical Manufacturing

Platinum-cured silicones are cleaner than peroxide-cured silicones, but choosing the right elastomer is about more than the cure system. Some medical silicones need to meet USP Class VI requirements. Samples of SSP-2390 have been USP Class VI certified by an independent laboratory.
