Rubber Bulb Trim Materials

Bulb Trim Seal Compounds, Colors, and ApprovalsBulb trim seal compounds, colors, and approvals may surprise you.

Bulb trim seals don’t just come in EPDM rubber. They’re available in colors besides black, too. That’s good news if you need to use recyclable materials, or if you’re searching for colorful sealing solutions to complement distinctive product designs. Bulb trim seals that contain EPDM aren’t all the same either. Some meet specific industry or regulatory standards. Others are made of harder or softer rubber.

Do you need bulb trim seals for doors, hatches, or enclosures? In this week’s blog entry, Elasto Proxy’s last for 2017, we’ll finish the year with a flourish – and with a look at some of the compounds, colors, and approvals for bulb trim seals. Black EPDM gaskets are available if you need them, but procurement and engineering personnel may have more choices in compounds than they may realize. (more…)

Rubber Bulb Trim Dimensions

Bulb Trim Seal MeasurementsLearn about bulb trim seal measurements from Elasto Proxy. 

Bulb trim seals are industrial rubber products that are used to seal and insulate doors, hatches, and enclosures. They fit radiused corners and have separate bulb and retainer sections, each of which can have a different durometer (hardness) and use a different material. The bulb compresses to form a seal when the door, hatch, or enclosure is closed. The trim or retainer attaches to the flange or substrate.

There are many different types of bulb trim seals, and plenty to learn about these industrial rubber products. In this two-part series from Elasto Proxy, we’ll examine three bulb trim seal measurements that engineers need to specify: bulb size, bend radius, and flange thickness. (more…)

Silicone Couplers

Silicone ConnectorsSilicone couplers are molded rubber parts that connect the intake pipes and tubes in diesel-powered vehicles and heavy equipment. These engine components resist high temperatures while providing strength and flexibility. Typically, silicone couplers are used in mobile equipment such as generator sets (gensets), ships and boats, and on-road and off-road equipment for forestry, mining, construction, and agriculture.

EPDM Rubber Gaskets 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. (more…)

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. (more…)

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. (more…)

TPE Reduces 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? (more…)

Rubber Bulb Trim Basics

Bulb Trim SealsBulb trim seals are used with doors, hatches, and enclosures. They have two sections: the bulb and the retainer. The bulb section provides sealing and insulation under compressive force. The trim or retainer section presses onto a flange or substrate.

Elasto Proxy supplies many different types of industrial rubber products, but there are three things about bulb trim seals that engineers need to know. (more…)

Rubber Gate Seal for Water Filtration System Lasts Longer, Resists Disinfection, Adds Business Value

Water Filtration Case StudyWhen a manufacturer of water filtration systems needed a rubber gate seal that would last longer and resist ultraviolet (UV) light, Elasto Proxy provided a value-added solution. This custom gasket doesn’t just resist exposure to water, contact with metal and concrete, and disinfection with UV light. The gate seal also supports ease-of-installation and is ready to ship from Elasto Proxy’s warehouse in Newmarket, Ontario.

The 60-durometer EPDM lip seal (J-seal) that Elasto Proxy provides attaches to the bottom of a metal gate used in water treatment facilities. This rubber seal is also compressed against hard concrete floors and exposed to a range of temperatures. UV disinfection kills waterborne microbes that can make people sick, but ultraviolet light can also degrade rubber materials. Without reliable sealing and strong bonding, gaskets like this can’t meet business or technical requirements.

To provide a complete sealing solution, Elasto Proxy leveraged its expertise in seal design, material selection, custom fabrication, warehousing, and logistics. (more…)
