Specialty Rubber Products You Didn’t Know That Elasto Proxy Supplies

Five ProductsElasto Proxy supplies industrial products that you probably didn’t know we offered. Why does this matter to you? Engineers need reliable parts that support larger product designs. Components that don’t work, won’t fit, fail in the field, or wear out too soon can cause project delays and cost overruns. If your current supplier can’t support your application, Elasto Proxy may offer an alternative.

Purchasing personnel also need suppliers who meet business and technical requirements. For purchasing agents, sticking with the same vendor may seem like the easiest way to do business. Yet it’s not always the best way, as sourcing managers can attest. As companies consolidate vendor lists to reduce operational expenses, they’re also buying more parts from suppliers with strong vendor scorecards.

In this article from Elasto Proxy, you’ll learn about five products that we offer that you probably didn’t know we did. Do you need rubber that’s bonded to metal, silicone hose, metallic-colored extrusions, molded plastic parts, or sewn products? If your company is buying these products from another supplier, you could save time and money by ordering them from Elasto Proxy instead. (more…)

The True Costs of Industrial Rubber Products

True CostsWhat are the true costs of industrial rubber products such as seals, gaskets, and insulation? Buying rubber materials and fabricating them in-house may seem cost-effective, but is your company really saving money? For that matter, are you sacrificing quality, consistency, and potential sales opportunities for a questionable cost savings?

Companies that want to know the true costs of industrial rubber products need to understand the full scope of their manufacturing costs. Typically, these costs are divided into three categories: direct labor, direct material, and manufacturing overhead. If any of these costs are incorrect, your financial statements may under-report inventory value and the cost of goods sold.

In this article from Elasto Proxy, we’ll examine each category of manufacturing costs so that you can consider how your in-house operations compare to outsourced fabrication. By understanding your true costs, you can make better business decisions and strengthen your manufacturing operations. (more…)

Four Ways to Cut Rubber Products

Cut Rubber ProductsWhat’s the best way to cut industrial rubber products like seals, gaskets, and insulation? Manual cutting, die cutting, water jet cutting, and abrasive water jet cutting each offer advantages. They also meet different business and technical requirements. As this article from Elasto Proxy explains, choosing the right cutting method for your application requires a complete and careful analysis. (more…)

Noise Control and Acoustic Insulation: Sound Sources and Frequencies

Noise Control and Acoustic InsulationAcoustic insulation absorbs, transmits, or redirects sound – a form of energy that travels in waves. Unwanted sounds, or noise, aren’t just unpleasant to hear. They can harm human health, jeopardize worker safety, and contribute to structural fatigue. The consequences of noise can be severe, but its characteristics are sometimes misunderstood.

In Part 1 of this series, Elasto Proxy shared a surprising example of two machines running at different decibel (dB) levels in the same room. In Part 2, we’ll examine some other sources of noise in the industries we serve. Importantly, you’ll learn why acoustic insulation must account for more than just a sound’s source. Frequency, the speed of the change of the sound, is a key design consideration for noise control. (more…)

Nitrile Rubber Products for Sealing and Insulation

Nitrile RubberWhen is nitrile rubber the right choice for sealing and insulation? This common elastomer is known by many names, including Buna-N, NBR, and acrylonitrile butadiene. There are plenty of trade names for nitrile, too. No matter what you call it, nitrile rubber offers good resistance to oils, fuels, and chemicals. Temperature and environmental conditions are limiting factors, however, and may require the selection of a more expensive material such as Viton™.

In this article from Elasto Proxy, you’ll learn about nitrile’s advantages and disadvantages. You’ll also examine NBR compounds, compare commercial and specialty Buna-N, and consider some typical nitrile applications. Elasto Proxy supplies specialty nitrile products to a variety of industries and can create a custom sealing solution that meets your specific requirements. Nitrile isn’t the only oil-resistant elastomer, but it’s a cost-effective choice compared to some other compounds.

Nitrile Advantages and Disadvantages

Nitrile rubber provides good-to-excellent resistance to many oils and solvents. Examples include:

  • animal and vegetable oils
  • crude petroleum oil
  • kerosene and gasoline
  • liquified petroleum (LP) gases
  • motor oils
  • mineral oil based hydraulic fluids
  • silicone greases and oils

For engineers and buyers, it’s important to understand that nitrile’s resistance to petroleum oils is limited by temperature. According to most chemical resistance charts, nitrile resists petroleum oil at temperatures up to 250° F (121° C). If your application requires both oil resistance and higher temperature resistance, a fluorocarbon such as Viton™ may be required instead. Nitrile is also unsuitable for highly polar solvents such as acetone, which is used in some food processing and medical applications.

Nitrile’s advantages include good physical properties such as resistance to compression set, tearing, and abrasion. Typically, NBR or Buna-N comes in durometers (Shore A) ranging from 20 to 95 for applications that require a softer or harder rubber. Nitrile resists water, but provides poor resistance to weather, ozone, and aging. Acrylonitrile butadiene is also unsuitable for some applications because Buna-N won’t withstand temperatures that are colder than -40° F (-40° C).

Nitrile Compounds and Specialty Grades

Through compounding, material suppliers have developed different types of nitrile with enhanced material properties. For example, hydrogenated nitrile butadiene rubber (HNBR) can withstand slightly higher temperatures than NBR and provides improved resistance to polar fluids. Carboxylated nitrile butadiene rubber (XNBR) has a higher compression set than Buna-N and offers improved tear and abrasion resistance. Nitrile can also be blended with polymers such as polyvinyl chloride (PVC).

For engineers and buyers, choosing the right type of nitrile may involve comparing commercial rubber to specialty grades. Commercial grades generally cost less and are available in higher minimum order quantities (MOQs). Specialty grades generally cost more and have larger MOQs, but they’re custom compounds with improved properties. ASTM D2000 provides a standard way to describe elastomers and uses the designations BF, BG, BK, and CH with both standard and specialty nitrile. (more…)

Commercial Grade Rubber vs. Specialty Rubber: Make the Right Choice

Commercial Grade RubberCommercial grade rubber provides sealing and insulation for a wide variety of applications. Compounds such as commercial grade EPDM, silicone, and neoprene also cost less than specialty rubber materials that meet standards, approvals, or regulatory requirements from organizations such as ASTM International, Underwriters Laboratories (UL), and the U.S. Food and Drug Administration (FDA).

For engineers, choosing the right rubber means understanding when a specialty material is required, and when a commercial grade rubber is sufficient. Engineers want to make sure that the products they design meet application requirements, but over-specifying an elastomer can incur unnecessary costs. In addition to paying more per unit of material, you may have to buy greater minimum order quantities (MOQs).

In this article from Elasto Proxy, we’ll consider the differences between commercial grade rubber and specialty rubber in terms of some real-world examples. You’ll also learn about some best practices that can strengthen your seal designs. (more…)
