ELBEX • January 21, 2016

Custom rubber extrusions from Elbex meet a wide variety of demands in industries like automotive, mass-transit, construction, water control, appliances, and more. Our extrusions help the engineers and designers working in these fields to bring together complex designs, improve tools, and accomplish their goals. With a variety of applications, uses, and materials that we make in house, our extrusions can help your engineers better meet the demands of your industry. 

Extrusion Applications

Extruded products stand out from molded rubber products because they are made under the pressure of a precise extrusion tool and design die. The resulting products allow for custom designs like: 

  • Architectural facades
  • Gap fillers for automotives, major appliances, and large scale machinery
  • Sheeting used to create barrier
  • Hollow tubing for water transport or storage

These are only some of the many applications that clients have found for our rubber extrusions, and with a high level of customization, it’s possible that you someone might bring us a new application, pushing the utility of our products even father. 

Materials to Match 

The two primary materials we use to create these diverse products are rubber and silicone. Silicone is most often employed in the creation of sheeting for barriers, but we always match the material with the project to ensure the best solutions possible. Whatever the material is, we ensure that the difficult geometry, quality assurance, and customer satisfaction is all handled in-house to make sure that not only will the material match the application, but it is processed with the care and attention necessary to match our high standards. 

If your engineers have been searching for new, durable, and custom solutions to a design issue, our extruded rubber products could be the piece that you were missing. With the help of our expert engineers we can find a solution to multiple issues and create the tool that you require.

Filling voids with reliable seals is a constant challenge in industrial environments. Without the right fit, seals won’t perform their job right, resulting in poor performance and even the contamination of sensitive environments. This is where Elbex’s ribbed rubber profiles come in. Our custom ribbed sealing profiles offer superior compression and sealing power by being tailored to your specific application needs. Here’s how our custom ribbed rubber profiles can make a difference for you. The Function and Superiority of Ribbed Sealing Profiles Ribbed sealing profiles play a vital role in manufacturing and industrial applications by filling voids or gaps between two surfaces to create an effective seal. However, ribbed rubber profiles take things even further, as their “ribs” significantly increase the profile’s ability to compress and fill irregularities. This results in a tighter and more durable seal than what you would find with a smooth profile, which also makes ribbed profiles far more versatile. Custom Design is Our Standard for Industrial Applications We are proud of our ability to deliver custom-manufactured ribbed sealing profiles that meet your exact requirements. We can work with you directly to develop the perfect custom ribbed rubber profile, as our extensive capabilities allow us to meet almost any design. Aside from the design itself, we use top-quality materials to help our seal products withstand harsh environments, including direct sunlight and chemical exposure, so the finished profile will deliver lasting performance. Leveraging Elbex's Comprehensive Engineering Expertise At Elbex, we are committed to delivering dependable support throughout the design and engineering processes. Our in-house tool and die design capabilities allow us to create custom ribbed rubber profiles in a way that meets your budget and timeline needs.

Choosing rubber materials can make all the difference for the performance and longevity of your rubber extrusions. The wrong choice can lead to compromised performance and even product failure or costly redesigns – so it’s normal to feel overwhelmed by this decision. Fortunately, with Elbex’s data-driven material selection criteria for specific rubber extrusion applications, you don’t have to leave this chance. Here’s how we help you pick the right materials, every time. The Guiding Questions: Elbex's Strategic Selection Process Choosing the right materials largely comes down to asking in-depth questions to understand the application and its operating environment. Our engineers ask critical questions like: What will the part’s primary function be? What are the application’s temperature requirements (both high and low)? Will the part be exposed to specific chemicals or fluids? Will the part be located indoors or outdoors (UV, ozone, weather exposure)? Does the part need to meet any regulatory requirements, such as food-grade, fire-retardant? What is the target cost per part?  The answers to these questions allow us to select the right compound for each extrusion, ensuring optimal performance while still fitting within your budget. A Closer Look: Key Elastomer Properties & Their Applications When selecting rubber materials for different applications, we look at their distinct characteristics. For example, durometer (or hardness) directly impacts a material’s sealing and abrasion. You generally want a softer material for better sealing, but harder for durability. Here’s how some of the most common elastomers compare: Silicone rubber: Silicone rubber properties include solid performance in both extremely hot and very cold temperatures, excellent flexibility, and strong UV/weathering resistance. Silicone is often used in high-heat applications, as well as the medical and food industries. EPDM rubber: Common EPDM rubber applications include outdoor seals, gaskets, and weatherstripping. This material’s resistance to water, ozone, sunlight, and weathering make it great for outdoor use. Neoprene rubber: Neoprene rubber applications can be quite varied thanks to its resistance to oil, heat, and flame. This versatile, all-purpose material is often a good fit for industrial and automotive applications. Nitrile rubber: Like neoprene, nitrile rubber applications often include the automotive and manufacturing industries thanks to its excellent resistance to oils, fuels, and many chemicals. The Elbex Advantage: Expertise at Your Service Choosing rubber materials is a critical step in any project. With Elbex on your side as a true collaborative partner, you get the unparalleled expertise and guidance you need to make the right choice, every time. Our goal is to empower you with useful information and help you find value-driven solutions that balance your cost and performance needs.

Modern architecture needs to deliver both aesthetic appeal and long-term building performance. This requires components that help buildings withstand harsh exterior conditions while maintaining their structural integrity. With Elbex, you get an expert partner who can produce a wide range of custom rubber profiles for architecture. Here’s how we can help. The Unseen Heroes: Functions of Architectural Rubber Architectural rubber extrusions play a variety of essential roles in modern buildings. They fill voids and seal surfaces to keep out air, water, and sound for energy efficiency and occupant comfort. UV-resistant rubber profiles for facades ensure a proper fit between different building materials. Many glazing systems and seals reduce vibration and prevent noise. All of these solutions work together to improve building durability and performance. A Crucial Differentiator: UV and Ozone Resistance UV and ozone resistant rubber extrusions for exterior architectural applications are especially important for building projects. Over time, exposure to ultraviolet rays and ozone can cause standard rubber to crack, become brittle, and lose its sealing properties. UV and ozone resistant profiles use carefully formulated material mixtures to prevent these issues and better protect the building's aesthetic and functional performance. A Portfolio of Precision-Engineered Solutions At Elbex, we produce a wide portfolio of rubber extrusions specifically formulated for architectural needs. Glazing systems set glass, provide environmental barriers and reduce vibration. Gaskets and seals protect against water, air, and sound. Bulb seals provide maximum sealing power for doors, windows, and hatches, while D-sections fill voids to provide sealing, vibration, and noise control. Setting blocks minimize uneven surfaces and provide support by positioning and seating materials. We also produce silicone sheeting, which can be used in a wide range of architectural projects.
