Unlocking the Power of Rubber: Understanding Elastomer Properties for Optimal Performance

April 18, 2025

Rubber elastomers are used in countless industries and applications, from automobiles to architecture. However, understanding the physical properties of rubber elastomers is essential for getting the right material for the right application. At Elbex, our deep understanding of elastomer characteristics ensures you’ll get the right match for your project.


Key Properties of Rubber Elastomers


The following properties are critical when considering which rubber elastomer is right for your application:


  • Elasticity and resilience: Rubber has the ability to deform under stress and then return to its original shape. Important in vibration damping and shock absorption.
  • Tensile strength and elongation: The ability to stretch and withstand pulling forces without breaking.
  • Hardness: Is the rubber flexible or rigid? This affects its abrasion resistance and compression set.
  • Compression set: Compression set is a permanent deformation that occurs after prolonged compression. Long-term sealing or cushioning applications require a low compression set.
  • Temperature resistance: The elastomer’s ability to withstand high and/or low temperatures – important when considering the application’s operating temperature range.
  • Chemical resistance: An elastomer’s resistance to any chemicals, oils, and solvents that might be present in its operating environment.
  • Weathering and ozone resistance: The elastomer’s ability to withstand sunlight, ozone, and other environmental factors are especially important for outdoor applications.


Common Types of Elastomers and Their Applications


The following are some of the most common types of rubber elastomers:


  • Natural Rubber (NR): Used for tires, footwear, and adhesives, natural rubber is known for offering excellent elasticity, resilience, and tear resistance.
  • Styrene-Butadiene Rubber (SBR): This cost-effective elastomer offers good abrasion resistance. It is commonly used in tires, conveyor belts, and footwear.
  • Ethylene Propylene Diene Monomer (EPDM): EPDM offers excellent resistance to weathering, ozone, and heat. As a result, it is the go-to option for rubber roofing, as well as automotive seals and hoses.
  • Nitrile Rubber (NBR): With resistance to oil, fuel, and chemicals, nitrile is commonly used for automotive and industrial seals and gaskets.
  • Silicone Rubber (VMQ): Usable in a wide range of temperatures, while also offering excellent electrical insulation properties and biocompatibility, silicone is a top choice for medical devices, cookware, and electronics.
  • Neoprene Rubber (CR): Neoprene’s flame resistance, oil resistance, and weather resistance means it is frequently used for applications such as wetsuits, adhesives, and automotive components.

In manufacturing, precise tooling is an absolute must, especially when creating custom extrusions. Outsourcing tooling may seem like a good idea, but this can often lead to delays and poor quality control. Instead, working with Elbex, which offers in-house tool and die design and custom tooling capabilities, can ensure you get the efficiency and quality you need. The Elbex Advantage: On-Site Tooling for Unmatched Efficiency In-house tooling provides several noteworthy advantages for your project. First, doing everything in-house eliminates outsourcing costs, which can result in significant cost savings. Doing everything in-house also streamlines the production process, dramatically reducing lead times, minimizing delays, and improving the overall project workflow. All of this enables us to improve the delivery schedule for your finished products and ensure that deadlines are met. Perhaps most importantly, however, doing everything in-house allows us to maintain meticulous control over the entire process, ensuring that finished seals and gaskets meet quality standards. Elbex’s Tooling Capabilities: From Design to Production At Elbex, we offer a wide range of custom tooling capabilities that benefit the entire manufacturing process. We use AutoCAD to create precise 2-D models, which are the foundation for accurate tooling. Our engineers also leverage their industry expertise to optimize tool and die design for specific materials and profiles. During production, we use wire EDM to create intricate shapes and complex profiles with exceptional precision, as well as sinker EDM to create complex cavities and shapes in dies and molds. Precise cuts and finishes enabled by these processes ensure consistent quality for rubber seals and gaskets, even with intricate designs. The Elbex Process: A Seamless Experience By keeping everything in-house, we offer a streamlined experience from start to finish. We begin by assessing your needs and defining tooling requirements during an initial consultation. After this, our engineering team gets to work, using AutoCAD to design and model the tooling. Once the design phase is complete, we can begin manufacturing in-house, using wire EDM, sinker EDM, and other processes as needed to achieve custom tooling. Rigorous quality control measures are implemented throughout production so that both tool and die design, as well as finished seals and gaskets, meet all necessary quality standards. With our on-site custom tooling capabilities, Elbex can deliver a seamless experience at every stage of the project, while achieving the consistent quality you need.
