The Difference Between Rubber and Plastic | EPDM vs. Silicone 


Cooper Standard ISG has the expertise to work with EPDM materials of all kinds, effectively building in the desired properties for any louver and damper application. EPDM options range from soft to firm, and include a light-density sponge for weight reduction. See more about our EPDM materials and how we can optimize applications with high-quality rubber. 


Often specified for high-temperature applications, silicone is the go-to material to keep heat and dust protected from louver and damper applications. Cooper Standard ISG expertise can help develop a seal with optimum properties for the most severe conditions. Learn more about our silicone properties and capabilities


Cooper Standard ISG engineers can help you develop a superior cost/performance value story with our in-house thermoplastic material expertise, including polypropylene, polyethylene, nylon, Santoprene, and Fortrex™. Learn more about our thermoplastic materials and how they can improve your next project. 

Accelerate Installation and Assembly with Value-Added Capabilities

At Cooper Standard ISG, we look for opportunities to optimize assembly efficiencies, reduce assembly costs, improve ergonomics and more.  Whatever the need, Cooper Standard ISG can be a go-to partner for adding value in strategic and innovative ways. 

Adhesive Laminating

Attaching high-performance, pressure-sensitive adhesive strips to both EPDM and silicone seals provides fast and easy installation at your facility. Learn more about how to choose the rubber adhesives that best fit your needs. 

Dual-Durometer Seals

Seals combined with two or more materials are known to provide ease of assembly and deliver optimum compression, deflection, and other performance properties. See more about our custom extrusion solutions.

Custom Color

Seals are not only available in black, but can be extruded in other colors, such as gray, white, and brown for advanced aesthetics for windshield trim. 

Custom Cutting

We can cut your extrusions to the exact length needed, as well a precision notch or punch seals to fit over bolts and other features in your fixture.

Custom Splicing

Cooper Standard ISG can create custom o-rings and other continuous seals by utilizing high-quality splicing processes, such as adhesives, heat splicing and transfer molding to help save assembly time and ensure tight tolerance and accuracy.

Push-Pin Seals

An alternative to adhesives in some applications, seals can be produced with precisely spaced pins for fast and easy assembly.

Specialty Engineering Solutions

Through leveraging advanced technologies, as well as a team of experts, we provide a range of comprehensive solutions that are tailored to meet diverse sealing requirements with utmost precision. These include: 

Molded Products

For large and/or intricate profiles, ISG offers extensive expertise in molding rubber and plastic seals and gaskets, using processes including compression molding, transfer molding, injection molding and more.

Rubber To Metal Bonding

A complex process demanding tight tolerances, specialized materials and processing expertise, rubber to metal bonding can enable a host of performance advantages including vibration damping, longer component life, superior insulation and more.

iDea® Seal Technology
