EPDM Rubber for Sealing and Insulation

EPDM Rubber

When is EPDM rubber the right choice for sealing and insulation? EPDM seals and gaskets are used widely with vehicles and equipment, but this synthetic elastomer has unsatisfactory resistance to gasoline, diesel fuel, and motor oil. EPDM’s advantages are numerous, however, and this cost-effective compound is often a better choice than silicones – especially in outdoor environments.

If you’re wondering whether EPDM is the right choice for your sealing and insulation application, Elasto Proxy invites you to take a closer look at this M-class elastomer. The M in M-class indicates that EPDM is part of ASTM D1418, a common specification for characterizing rubber compounds. Often, design or product engineers use ASTM specs to designate the rubber material on a part drawing.

In this article, we’ll examine EPDM’s advantages and applications. We’ll also consider its disadvantages – and consider how EPDM rubber compares to some other materials. Finally, we’ll look at how EPDM is supplied and fabricated. Continue reading EPDM Rubber for Sealing and Insulation

How Silicone Rubber Is Used for Sealing and Insulation

Silicone RubberHow is silicone rubber used for sealing and insulation? Silicones have valuable properties, but engineers need rubber that meets specific requirements. If you’re wondering whether silicone seals, gaskets, or insulation are the right choice for your application, consider some of the uses for this versatile polymer.    The examples you’ll read about aren’t the only uses for silicone, but they’re representative. Continue reading How Silicone Rubber Is Used for Sealing and Insulation

When to Use Silicone Rubber for Sealing and Insulation

Silicone RubberWhen is silicone rubber the right choice for sealing and insulation? Silicones have many desirable properties, but can cost more than other polymers. That’s why some engineers avoid them – even though silicone prices have fallen. At the same time, newer materials such as thermoplastic elastomers (TPE) are interesting but even more expensive.

If you’re wondering whether silicone rubber is the right choice for your application, Elasto Proxy invites you to take a fresh look at these synthetic elastomers. In Part 1 of this two-part series, we’ll examine the advantages of silicone rubber, cover some basic chemistry, and then focus on silicone gasket materials. Next, we’ll categorize silicones in different ways so that you’ll be ready to understand the applications. Continue reading When to Use Silicone Rubber for Sealing and Insulation

TPE Profiles Reduce Waste, Glow in the Dark, Feature Custom Colors

TPE ProfilesTPE profiles are replacing EPDM rubber in applications such as mobile equipment, food equipment, and infrastructure. Unlike EPDM, thermoplastic elastomers (TPE) are recyclable. That’s especially important in Europe, where manufacturers are moving away from petroleum-based materials.

In North America and other parts of the world, the availability of TPEs in custom colors is driving demand. TPEs can cost more than EPDM profiles, but thermoplastic rubbers (TPRs) – as TPEs are sometimes called – offer important advantages for product designers and engineers. Are TPE profiles the right choice for your next project? Continue reading TPE Profiles Reduce Waste, Glow in the Dark, Feature Custom Colors
