USA-Based Custom EMI Gasket Manufacturer & Elastomer Compounder
Specialty Silicone Products (SSP) is a premier ISO 9001:2015 certified manufacturer of custom EMI gaskets, conductive elastomers, and RFI shielding solutions. Based in Ballston Spa, New York, we handle every stage of production—from custom compound formulation and particle filling to precision molding, extrusion, and die-cutting.
Whether you need MIL-DTL-83528 QPL-listed materials for military avionics or cost-effective conductive silicone extrusions for commercial electronics, SSP delivers high-performance EMI gaskets with industry-leading lead times.
Complete EMI Gasket Manufacturing Capabilities
We offer flexible, in-house manufacturing capabilities to meet exact mechanical specs, environmental requirements, and budget targets:
Compression Molding: Precision-molded O-rings, custom profiles, flat sheet gaskets, and complex 3D geometry designed to meet strict shielding specifications.
Extrusions & O-Rings: Conductive silicone and fluorosilicone profiles, including solid cord, hollow O-tubing, channels, and bonded or continuous vulcanized O-rings.
Die-Cutting & Fabrication: High-speed die-cutting and custom fabrication from filled silicone sheeting with low closure force options.
In-House Tooling & Prototyping: Rapid prototyping and custom tooling development to accelerate your product design cycle.

Frequently Asked Questions
What is the lead time for custom EMI gaskets?
Standard conductive sheeting and extrusions typically ship within 3 to 4 weeks. Custom molded shapes and specialized tooling schedules are provided upon quote request.
Does SSP manufacture EMI gaskets compliant with MIL-DTL-83528?
Yes. SSP produces QPL-listed conductive silicone and fluorosilicone materials compliant with MIL-DTL-83528 specifications for defense and aerospace applications.
Can SSP supply pressure-sensitive adhesive (PSA) backings on EMI gaskets?
Yes. We offer non-conductive and electrically conductive pressure-sensitive adhesive (PSA) backings to simplify assembly and mounting.
