Elbex - Custom Rubber Extrusions

At ELBEX, we work tirelessly to exceed customer expectations and manufacture high-quality rubber extrusions. A big part of our ability to meet these goals comes from the wide variety of profiles we can manufacture — including bulb seals, bumpers, and D-Section profiles.

Bulb Seals

Bulb seals create a seal by taking on the shape of the channel or void they need to fill. To that end, we offer several standard bulb seal extrusions, while also using our in-house team to develop custom bulb seals when necessary. We use different materials based on the needs of the application or environment to ensure reliable performance.

Bumpers

Bumper extrusions form a cushion that reduces movement and vibrations, especially from impacts. These extrusions are helpful in applications where the movement of the equipment has the potential to damage other property or the equipment itself. We typically use EPDM for bumper profiles because of its high abrasion resistance.

D-Section Profiles

D-Section profiles are similar to bulb seals in that they are often used to fill voids or create a seal between two different surfaces. Their name comes from their distinctive shape, which looks like the letter “D.” They typically use a pressure-sensitive adhesive that is applied to the flat end to remain stationary. Though used in a wide range of industries and applications, they are most often used to create a weather seal around windows and doors.

No matter what type of extrusion you need for your application, you can trust our team to perfectly meet your project requirements. Contact us today to learn more about how we can turn your application into a reality.

“Bumps and bruises" are inevitable in busy industrial environments. But whether these incidents cause major damage to equipment and infrastructure often depends on whether or not you use extruded rubber bumpers. Impact-resistant rubber bumpers for manufacturing facilities provide a high level of protection against collisions, ensuring that such incidents don’t lead to even bigger problems. With custom rubber bumpers from Elbex, you can have even greater confidence that your equipment, vehicles, and infrastructure are properly protected. The Versatility of Extruded Protection Not all rubber bumpers are created equal. At Elbex, we use the rubber extrusion process, which allows us to produce rubber bumpers in long, continuous lengths. The curing that rubber components go through during rubber extrusion provides superior linear strength and durability when compared to molded alternatives, especially for lengthy bumpers. This process allows us to produce rubber bumpers for a wide range of applications. We can produce bumpers for loading dock protection in mass transit, or to protect docks and boat hulls in the marine industry. We can even produce custom bumpers to protect expensive machinery from forklift or trolley impacts. Designed to Take the Hit For industrial rubber bumpers, few things are more important than the right material. That’s why we use EPDM as our material of choice for these applications. EPDM’s strong abrasion resistance helps it withstand the wear and tear of harsh industrial environments. In addition, these impact resistant rubber bumpers for manufacturing absorb the energy of collisions. This helps them reduce vibration and structural stress on the equipment that is being protected, in addition to preventing surface-level scratches. Custom Profiles for Specific Risks The combination of the rubber extrusion process and our team’s industry expertise enables us to create heavy duty rubber bumpers for industrial equipment in a wide range of shapes and lengths. Whether you need D-sections, U-channels, or something else entirely, we’ll help you get the right fit. And with our salt-bath curing process, you can expect continuous quality and durability from end to end. A small investment in high-quality bumpers can help you save thousands in repairs to industrial structures and equipment. With Elbex, you’ll get the customized level of protection your facility needs. Contact us today to learn more about our capabilities or to request a quote for your facility.

Effective sealing goes a long way in protecting products, buildings, and equipment from air, water, and environmental exposure. Rubber bulb seals may seem simple, but there’s a good reason why they are used across industries: they are extremely effective. Bulb seal extrusions provide rubber sealing profiles that create tight, consistent seals in a variety of use cases. For example, extruded rubber bulb seals for weatherproofing prevent leaks and improve insulation. Custom rubber bulb seals for doors and windows are especially effective at providing precise fit and performance. With Elbex on your side, you can get the reliable, high-quality sealing that you need. Here’s a closer look at how rubber bulb seals can make a difference for your projects. How Rubber Bulb Seals Work Bulb seals offer a simple, yet remarkably effective design. The hollow bulb shape allows for compression, which then creates a tight seal when pressure is applied. This flexibility helps the seal maintain its performance over time and at a variety of pressures. Even with movement or vibration, proper design ensures consistent sealing against air, water, and noise, while also improving insulation. Sealing Efficiency and Performance Benefits Compared to flat or rigid profiles, bulb seals have a much greater ability to adapt to uneven surfaces and gaps. This results in greater sealing efficiency, durability, and long-term performance, even in demanding industrial environments. With well-designed rubber sealing profiles tailored to your application’s environmental hazards, you can further reduce maintenance needs and increase the lifespan of your seals. Applications Across Industries The versatility and adaptability of extruded rubber bulb seals for weatherproofing makes them a top selection across multiple applications and industries. In construction and architecture, you’ll find bulb seals in doors, windows, and curtain walls. Bulb seals are also used for industrial equipment enclosures and machinery sealing. You’ll find them in mass transit vehicle doors, windows, and compartments. And bulb seals are even used for sealing temperature-controlled environments in appliances. Their versatility is truly amazing. Custom Rubber Bulb Seals for Precision Fit As versatile as bulb seals are, customization is still critical for dependable sealing performance. At Elbex, our team has the expertise and equipment necessary to produce custom rubber bulb seals for doors and windows as well as other specialized industrial applications. With in-house tooling and die design, material selection and design support, and the ability to produce seals in continuous lengths and consistent profiles, we’ll help you get the best results for any application.
