What is SBR?

SBR, also known as BunaS, is a synthetic copolymer of styrene and butadiene. SBR was originally developed to replace natural rubber in tires and its use in the manufacture of tires continues to the present day. SBR and natural rubber account for 90% of the total world rubber consumption. SBR has a typical service temperature range between –50° F and +225° F.

ADVANTAGES:

SBR has similar properties to natural rubber, but SBR has superior water resistance, heat resistance, abrasion resistance, low temperature flexibility, and heat aging properties (i.e., in excess heat SBR hardens and becomes brittle instead of softening like natural rubber does). SBR also has good electrical insulation, alcohol resistance, oxygenated solvent resistance, and mild acid resistance. SBR can be successfully bonded to a wide range of materials.

LIMITATIONS:

SBR has poor resistance to oils, fuels, hydraulic fluids, strong acids, greases, fat, and most hydrocarbons. Without special additives, SBR is vulnerable to ozone, oxygen and sunlight.

COMMON APPLICATIONS:

SBR is recommended for applications where water, automotive brake fluid, or alcohols with a low molecular weight are present. Common applications include tire, tubes, gaskets, belts, hoses, seals, shock mounts, skirt board rubber, lining rubber, and conveyor belt covers. SBR is not normally produced in o-ring form.

Durometer

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer number, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion/extrusion resistance.

Typical Questions Asked

What is the application or function of the part?
Is there a target cost per part that should be considered?
Will the part be located inside or outside?
What, if any, are the temperature requirements?
Is there exposure to specific chemicals?

2024 and Beyond: ELBEX’s Vision for the Future of Rubber Extrusion

27 Mar, 2024

We live in a time of rapid change — and this is just as true of the rubber extrusion industry as it is in other areas. At ELBEX, we believe a forward-thinking approach is vital to stay at the forefront of rubber extrusion. Emerging Trends in Rubber Extrusion in 2024 As 2024 begins, several trends have stood out in the rubber extrusion industry. These include advancements in eco-friendly materials, improvements in manufacturing automation, and increased demand for rubber extrusions from emerging markets. At ELBEX, ongoing investments in research and development have proven essential for helping us take advantage of these trends so we can better serve our clients. Incorporating Advanced Technology Manufacturing processes are constantly improving thanks to new technologies such as AI and the internet of things. These technologies enable us to automate certain processes to achieve greater efficiency, quality control, and customization capabilities. Sustainability: A Core Focus for ELBEX in 2024 Energy efficiency and the use of eco-friendly materials have long been a focus at ELBEX, but they are even more important in 2024. Current sustainability initiatives include the use of recycled materials and a focus on implementing energy-efficient processes that minimize waste. Expanding into New Markets and Applications New industries and markets represent a major area of growth for rubber extrusion products. Areas such as renewable energy, electric vehicles, and smart infrastructure will all rely on rubber extrusions, and as such, we must continually research and develop new profiles that will work with these applications. ELBEX’s Commitment to Quality and Customer Satisfaction In the midst of these trends, ELBEX is committed to maintaining high quality standards, as demonstrated through our ISO certification. By taking advantage of the latest industry trends, we can further improve results for our clients and drive meaningful outcomes. With a proactive approach to embracing current and future trends in the world of rubber extrusions, ELBEX is positioned to continue shaping the future of the industry in 2024 and beyond.

Maximizing Efficiency, Minimizing Waste: ELBEX’s Low Scrap Success in Rubber Extrusion

19 Mar, 2024

One of the most important indicators of a manufacturer’s efficiency is its scrap rate — or the percentage of defective products that need to be thrown away or recycled. At ELBEX, we are proud to consistently achieve low scrap percentages with each job we undertake. The Importance of Low Scrap in Manufacturing In manufacturing, scrap can have significant environmental and economic impacts. Unusable products must be recycled and replaced, which means more time, energy, and materials used in the manufacturing process. This can drive up costs for both the business and its clients, while also creating a larger carbon footprint. ELBEX’s Approach to Minimizing Scrap At ELBEX, we implement a wide variety of steps to minimize scrap, starting by using high-quality materials that are less likely to result in defects. We combine this with the latest in rubber extrusion technology and processes and a skilled team that draws on decades of industry experience. Strong quality control systems help us reduce waste at every step of the process. Impact on Quality and Cost-Effectiveness These practices, which help us achieve a low scrap percentage, ultimately result in higher quality products and less waste. This creates cost savings for everyone involved, as production runs can be completed faster and with less material. Reduced energy consumption also means less of an impact on the environment. ELBEX’s Ongoing Commitment to Improvement ELBEX is committed to continuous improvement, including finding new ways to further reduce scrap and enhance efficiency. By embracing new technology and sourcing the highest-quality materials, we can become even more sustainable and cost-efficient. At ELBEX, we believe our low scrap percentage is an indicator of our efficiency, quality, and environmental responsibility. While there is always room for improvement, we’re proud of what we’ve achieved so far and how it can help you, too.
