Everything You Need to Know About Expansion Joints
ELBEX • December 6, 2021
Expansion joints play a vital role in a wide range of construction projects, helping to hold separate components together while also lessening the impact of vibrations and temperature-related expansion and contraction. Quality materials and design are an absolute must for this important rubber extrusion.
Protecting Structural Applications
Expansion joints protect building materials from structural stress, which is primarily caused by temperature-related activity. Concrete, building faces, glass, and even pipelines expand and contract as a result of seasonal warming and cooling, as well as exposure to other nearby sources of heat. Without an expansion joint in place, the added pressure can cause materials to crack. Expansion joints help make the application more “flexible” by absorbing this stress and keeping materials from rubbing against each other. Expansion joints can also minimize damage from natural ground settling.
The Use of High-Quality Materials
Unsurprisingly, the quality of a rubber expansion joint is directly tied to the quality of the materials used in manufacturing. At Elbex, we use natural rubber products from high-quality sources to ensure that they will meet the desired performance requirements of a particular application. Accounting for unique environmental hazards (such as extreme temperatures or chemical exposure) helps enhance the longevity of a custom expansion joint.

Comfortable, quiet, and reliable mass transit is essential for delivering a great experience for passengers – but overcoming the pervasive challenges of noise and vibration isn’t easy. As a leading expert in providing specialized mass transit rubber extrusions, Elbex can help you produce vibration dampening rubber components and noise reducing rubber gaskets for mass transit vehicles that are tailored to your specific needs. The Demands of the Mass Transit Environment Mass transit is subjected to constant movement and structural flexing. Powerful engines, as well as vehicle interaction with tracks or roads, generates constant noise and vibration in transit vehicles. Over time, this can impact mass transit structural integrity. Excess noise and vibration can also cause discomfort for passengers, negatively impacting how the public views your transit system. Rubber extrusions play a vital role in dampening noise and vibrations. However, achieving lasting results requires rubber components that can withstand extreme temperatures, continuous stress, varying loads, and environmental factors such as UV, ozone, and moisture exposure. Elbex's Precision in Mass Transit Rubber Extrusions Elbex is uniquely positioned to address your mass transit rubber extrusion needs. Our deep understanding of highly resilient natural rubber, weather-resistant EPDM, oil-resistant Nitrile, shock-absorbing SBR, and other rubber compounds enables us to select the right material for each application. Materials are formulated for vibration dampening, thermal stability, and durability against transit-specific stressors. Our custom profile design and engineering capabilities are another valuable strength. Our team can collaborate with your transit engineers and designers to ensure perfect fit and functionality, even for complex sealing and dampening needs. Our extrusion and molding processes are designed for tight tolerances and consistent quality, while our ISO certifications guarantee the reliability and durability of each rubber extrusion. Core Solutions for Enhanced Transit Performance At Elbex, we offer a wide range of rubber extrusion solutions that can enhance transit performance. Engine mounts, suspension bushings, body mounts, and interior panel isolators isolate shocks and reduce resonant frequencies to extend vehicle lifespans, limit structural fatigue, and improve ride quality. We also produce noise reducing rubber gaskets for mass transit vehicles, including window and door seals, floor gaskets, and HVAC system seals. With the help of these acoustic and environmental barriers, your mass transit vehicles will have quieter cabins, enhanced passenger comfort, better thermal insulation, and protection against external elements like dust and water. Additional mass transit extrusions that contribute to vehicle integrity and performance include weatherstripping, bumper guards, D-seals, and custom tubing. No matter what you need, Elbex can provide high-quality, customizable solutions.

In industries like mass transit and construction, secure fitting and protected edges are key to the durability and safety of many applications. Rubber extrusions, particularly custom extruded u-channels and variations like ribbed rubber channels can play an essential role in these areas – and Elbex’s expertise in providing custom solutions will help you move forward with confidence. Understanding U-Channel Rubber Extrusions U-channel rubber extrusions are named for their distinctive U-shape, which allows them to fit over edges or within channels on mating pieces to ensure a secure fit and protect edges. The size and thickness of the legs and base should be adapted to the needs of the application, since precise dimensions are needed to get a secure fit. Depending on needs, extra features like ribbed rubber channels can be added for increased grip, vibration dampening, or sealing. As with other rubber extrusions, various materials, such as EPDM, neoprene, or silicone can be used for U-channels. The right material depends on the application’s environmental conditions (like temperature, chemicals, and UV exposure), as well as performance requirements such as flexibility and durability. Diverse Applications Across Industries U-channels serve a variety of important functions. They can be used as edge guards to protect surfaces from damage and provide a finished look, such as in automotive door edges, metal paneling, or machinery housings. The tight fit of these rubber extrusions within the channel also dampens vibrations and prevents unwanted movement between components. This is especially important for preventing excess wear and promoting structural integrity in transportation equipment and other machinery. U-channels are also used to create seals against dust, moisture, and other environmental elements. Weatherstripping in homes and glazing seals on building and automotive systems are common examples of this. With the right materials, U-channels can provide essential protection, even in extreme environments that undergo frequent temperature changes.

Rubber extrusions are incredibly versatile, used across a wide range of industries. At the same time, we recognize that understanding the basics of rubber extrusion for beginners can be challenging. In this blog, we’re going to provide a step by step overview of the rubber extrusions process, and how Elbex’s approach to the rubber extrusion process can benefit your company. The Fundamentals of Rubber Extrusion Rubber extrusion is a process in which uncured rubber materials (such as EPDM, silicone, neoprene, and nitrile) are forced through a shaped die. This is done to create a long, continuous profile, reducing waste and making the production of rubber extrusions more efficient. The extruder forces the rubber through the die, which can be adapted to create different shapes for different applications. The continuous profile then goes into a cooling system, where it cures and hardens. After it is cured, handling equipment allows the long profile to be cut to length to form multiple extrusions. Elbex's Streamlined Rubber Extrusion Process: A Step-by-Step Overview At Elbex, we follow a five-step process for streamlined rubber extrusion creation: Step One: Initial Consultation and Design Input. Most projects start when the client provides design information. This usually comes in the form of a drawing or sketch that provides a visual of the extrusion, or a physical sample that we can reverse engineer. Step Two: In-House Die Creation. Once we have a finished design, we manufacture our rubber extrusion dies in-house. By eliminating the need for external vendors, we can lower costs and provide a faster turnaround. This also ensures that the die is the proper shape for the extrusion. Step Three: The Extrusion Process. Once the custom-made die is ready, we use our extrusion equipment to force the heated rubber through the die. The right level of heat and pressure is essential to maintain the right shape during this step. Step Four: Curing and Vulcanization. After going through the die, the rubber is vulcanized (or cured) with chemicals like sulfur to help it harden and improve its physical traits. Step Five: Cooling and Handling. After the extrusion has cured, it needs to cool. Cooling completes the hardening process, after which the rubber can be cut to length or spooled based on application needs.
