Custom Rubber Extrusions


Our rubber extrusion operations are built on the belief that every customer's need is unique. Cooper Standard custom extrudes rubber for various industries from a wide variety of compounds, grades and specifications.

We can help you through the entire extrusion process – from choosing the right material to using the most cost-effective manufacturing methods.


Rubber sealing components protect, dampen vibration or aesthetically enhance finished products for appliance, HVAC, automotive, lighting, commercial & residential window and door, power sports, food services, electrical vehicles and many others.

There are many decisions to consider when designing a seal or gasket. When you partner with Cooper Standard, we offer the following services to develop or refine a seal that meets your custom needs.

  • Material Formulation and Testing
  • Engineering Design
  • 2D and 3D Finite Element Analysis (F.E.A.)
  • 3D Modeling
  • Equipment Development
  • In-house Tool Capabilities


Cooper Standard gives you access to advanced materials science and expertise. We can develop materials to meet industry standards. Partner with our engineers to discover what rubber material is right for you according to your unique specifications.

Featured Capabilities
Value-Added Capabilities

Coatings & Capstocks

Our various coating options can serve as an assembly aid or reduce noise, wear and abrasion. This process can be used to coat entire sheets or a localized area on each part.

Color Match

We offer color matching capabilities for silicone and organic compounds. For specific color requirements, please provide us with a sample or Pantone (PMS) number so we can match the color to your needs.

Extrusion Cutting Processes

We can finish products with a variety of cutting processes including: cut to length, punching, die-cutting, notching, drilling, kiss-cutting, slitting and custom cutting. In some cases, these finishing processes can be good alternatives to rubber molding.

Drilling & Punching Seals

Seals may require vent holes that enable the part to collapse under pressure. During part extrusion, holes can be drilled at precise, uniform intervals. Cut-to-length parts also can be placed in a punch press where a die creates the intended feature.


Flocking is a velour-textured material that can be applied to many polymers and dyed to match virtually any color. Flocked surfaces help reduce friction and water absorption while dampening vibration and offering thermal insulation.

Identification Printing

Identification marks on products can be crucial to manufacturing efficiency and quality. From an intricate logo to customer part numbers, we can provide identification markings that best fit your requirements.


Adhesive (tape) can often eliminate mechanical fastening systems (staples, nails or retaining clips) and their inherent challenges. Many different heat-activated and pressure-sensitive adhesives are available to meet your requirements. Learn how to choose rubber adhesives. 

Specialty Packaging

In addition to designing materials and profiles, we can specify and order your private label packaging to provide a complete product solution.

Push-Pin Seals

These seals provide an alternative to standard laminated seal methods with pins that are spaced according to your requirements.

Splicing and Welding

Splicing and welding can be used to form a simple O-ring or a complex multi-side product. We offer cold and hot splicing as well as transfer molded joints and vulcanized corners.

Multi-Durometer Extrusions

Multiple-durometer products combine two or more materials through a single die so that the extrusions merge together into one structure. The more rigid material serves as means of attachment, while the softer compound completes the seal.

iDea® Seal Technology

This co-polymer design features a custom or standard EPDM bulb and a rigid plastic base. The result is a seal with excellent compression set that easily slides into a channel and minimizes stretch.

Clip-on Seals

Rubber profiles are reinforced with steel or aluminum carriers for durable protection or an aesthetic finish. When a clip-on seal is coupled with a rubber or plastic profile, the result is a tight seal with excellent compression properties. Custom or catalog clip-on seals available. Push-on Trims, QuickEdge® Trims

Rubber Sheeting

We offer a variety of sponge and dense silicone sheets that can be used as manufactured or fabricated to suite a variety of application requirements.

Application Considerations

Explore the breadth of Cooper Standard’s materials offerings and the engineering expertise practiced when selecting the right material for an application.

Custom Extrusions: Rubber Vs Plastic

There are many variables to review when choosing between rubber and plastic. Cooper Standard has both material options, plus many years of experience servicing diverse industries with the right material for every unique application. Explore the science behind the selection process.

Custom Extrusions: EPDM vs. Silicone

When trying to meet stringent performance requirements, Cooper Standard offers EPDM and Silicone as popular seal and gasket materials. Knowing which material is the best option for a seal's environment and longevity while balancing cost is key.

Custom Extrusions: EPDM vs. Neoprene

In general, EPDM and Neoprene are both good multi-purpose materials that Cooper Standard offers, but each have specific properties that were created to meet your unique material specifications. Let’s explore their differences.
