CUSTOM GASKETS

Custom gaskets from Interstate provide superior sealing and insulation for medtech and scientific, electronics, industrial, and filtration applications.

Interstate Specialty Products manufactures custom gaskets from non-metallic materials such as rubber, Gore GR, Poron, and Teflon / PTFE. We can recommend the right gasket material and manufacturing method for your application, or use customer-supplied materials. For over 60 years, Interstate has specialized in custom gasket manufacturing. Here at our facility in Sutton, Massachusetts, we offer both precision die cutting and digital knife cutting services, as well as large format cutting and adhesive laminating services.

Rubber Gaskets

Custom rubber gaskets from Interstate meet all your application’s requirements. Interstate die cuts specialty gaskets from a wide range of elastomers, including natural and synthetic rubbers, solid elastomers, and sponge and foam elastomeric materials. We can also create custom gaskets from specialized or proprietary elastomers.

Ask Interstate to create rubber custom gaskets like these for your next project.

From low-volume runs to high-volume quantities, choose Interstate for custom gasket manufacturing that meets the tight tolerances your application requires.

Gore GR Gaskets

Custom Gore GR gaskets resist corrosive chemicals and high temperatures while providing excellent dielectric properties and dimensional stability. To create these specialty gaskets, Interstate converts Gore GR sheet gasketing, an expanded PTFE (ePTFE) from W.L. Gore & Associates. Custom gaskets made of this ePTFE provide greater resistance to creep and cold flow than PTFE, which is prone to deformation.

Interstate die cuts Gore GR material to exacting tolerances, and can supply custom Gore GR gaskets with adhesive backings. Adhesive backings promote ease-of-installation, especially with peel-and-stick gaskets that use pressure-sensitive adhesive (PSAs).

PTFE (Teflon) Gaskets

Teflon / PTFE custom gaskets from Interstate provide excellent thermal insulation and resist corrosive chemicals. Teflon, the DuPont brand name for polytetrafluoroethylene (PTFE), is a good choice when improved resistance to creep and cold flow is not required. Custom gaskets made of pure PTFE are chemically inert and water-resistant, but may deform under heavy use.

Interstate can die cut PTFE sheets to exacting tolerances and supply customized PTFE gaskets with fabric supports and adhesive backings. We can manufacture gaskets from virgin PTFE, or materials that contain PTFE and fillers for improved resistance to strong acids or caustics.

Poron Gaskets

Poron custom gaskets from Interstate provide shock absorption and impact protection along with sealing and insulation with excellent compression set resistance. They’re made of Poron microcellular urethanes from Rogers Corporation, and are available in different types or grades – such as Condux Plus foams for electrical resistance and Poron V-0 foam for UL94 flame resistance.

Interstate can craft custom Poron gaskets using precision die cutting or digital knife cutting from sheets, rolls, or spools. With Poron’s double-sided skin, applying PSAs is simple. These gaskets also work well with various adhesives. Specialty gaskets made of Poron foam can also meet exacting tolerances, an important consideration in small handheld devices such as cell phones.
