Sound Transmission Class (STC) and Acoustic Insulation

sound transmission classSound transmission class (STC) describes the ability of a product or material to stop the transmission of airborne sound. Since the 1960s, STC ratings have been used to describe the acoustical properties of ceilings, walls, floors, and doors. Today, STC values are provided for acoustic insulation made from a single material, and for multi-layer composites that are sandwiched together. Higher STC numbers are generally better, but there are exceptions to this rule – and other factors to consider as well.

In this article from Elasto Proxy, you’ll learn what STC is and how it’s measured. For starters, we’ll cover some basic concepts about sound, vibrations that travel through the air or another medium (such as a wall) and can be heard by the human ear. Along the way, it’s important to remember that sound can also be reflected inward (such as within a metal enclosure) and cause vibrations. So while preventing the transmission of unwanted sound (noise) is important, you may face other design challenges, too. (more…)

Custom Weather Stripping for Doors and Windows

custom weather strippingCustom weather stripping from Elasto Proxy can meet the challenges of static or dynamic sealing in hot or cold weather conditions.

Here in the northern hemisphere, the days are becoming colder. In Canada, where Elasto Proxy is headquartered, the snows will arrive long before December 21, the first day of winter. At offices and factories across North America, doors and windows that let warm air out and cold air in mean higher heating costs. Leaky door and windows can also make occupants less comfortable and workers less productive.

Standard weather stripping can help, but what if your sealing and insulation application requires a specialized solution? After all, off-the-shelf rubber products aren’t designed and manufactured with your specific needs in mind. For a custom sealing solution you can count on, choose weather stripping from Elasto Proxy. All weather stripping isn’t the same, and selecting a custom-fabricated rubber product can save you time and money in the end. (more…)

Three Types of Custom Silicone Gaskets

Custom Silicone GasketsCustom silicone gaskets provide strong environmental sealing and excellent temperature stability. They resist water, ozone, sunlight, weathering, and aging; withstand high temperatures; and maintain their flexibility at low temperatures. Silicone rubber is also chemically inert and provides good dielectric properties. Custom silicone gaskets can be categorized in various ways, but there are three basic types: solid, sponge, and foam.

For product designers and technical buyers, it’s important to understand the differences between these three types so that you can choose the right one for your application. Type is just one of many specifications you’ll need to consider, but it’s a good place to start. For example, depending on your application, you may need to choose a silicone that’s UL listed for flame-resistance or FDA approved for medical or food processing applications.

For over 25 years, Elasto Proxy has been helping companies like yours get the custom silicone gaskets that they really need. In addition to design assistance and help with compound selection, we provide gasket fabrication services that are fast, dependable, and cost-effective. From prototyping and custom fabrication to warehousing and shipping, Elasto Proxy saves you time and money. (more…)

Seals and Insulation for Military Projects at AUSA 2016

military projectsIs your company part of the defense community? Do you design, build, or buy components for military projects such as vehicles? Are you headed to AUSA 2016 next week? From October 3 to 5, 2016, leading defense contractors and subcontractors will join military officers and government officials for the annual meeting and exposition of the Association of the United States Army (AUSA). Held at the Walter E. Washington Convention Center in Washington, D.C., AUSA 2016 is where you’ll learn about the latest in land power.

As an experienced member of the defense supply chain, Elasto Proxy will be in Washington for this important event. Robert Naccarato, Elasto Proxy’s Sales Manager, and Tom Henry, U.S. Branch Manager, invite you to join them in the Canadian Pavilion, or to arrange a meeting in another tradeshow location at your convenience. If you need custom seals, gaskets, or insulation for military vehicles, you’ll want to take advantage of this special opportunity. (more…)

Rubber Hatch Seal Case Study

military vehiclesRubber hatch seals for military vehicles don’t just keep out wind, water, dirt, and mud. They need to withstand extreme temperatures and various weather conditions. Hatch seals must avoid compression set, too. If a vehicle’s hatch causes a rubber seal to over-compress, the part won’t provide proper sealing. Ultimately, this permanent deformation creates a gap and causes seal failure. That’s bad news for military vehicles and the highly-trained personnel who operate them.

In this case study from Elasto Proxy, you’ll learn how we solved a sealing challenge for a manufacturer of military vehicles. The rubber hatch seals that we supply resist over-compression and demonstrate the value that we add to defense contracts. For our 25 years, Elasto Proxy has been an important link in the military supply chain. Elasto Proxyalso holds a Controlled Good Certificate (CGC) and works closely with trade groups such as the Canadian Association of Defense and Security Industries (CADSI). (more…)

What’s the Right Rubber Tubing for Your Application?

Rubber TubingRubber tubing is used in fluid transport and for electrical protection. Applications include shock absorption and low compression force sealing. Different elastomers have different properties, so design engineers and technical buyers need to choose rubber tubes carefully. Specifications such as durometer (hardness) and inner and outer diameter are especially important to consider.

By choosing the right rubber compound for industrial tubing, you can strengthen your company’s product designs. You can also control costs by selecting rubber tubes that are cut-to-size and ready-to-install. Metal tubes resist high temperatures and provide physical strength, but they cost more than rubber tubes. Plus, metal tubing may be subject to rust, corrosion, or scaling. (more…)

Military Acoustic Thermal Insulation

Americans say “Zee” for the letter Z. Canadians say “Zed” instead. In both North American countries, their militaries say “Zulu” so that radio or telephone messages can be understood clearly. If you’re a defense contractor that makes military vehicles, it’s important to know you’ll receive exactly what you asked for. Elasto Proxy, a trusted member of the defense supply chain, can custom-fabricate thermal acoustic insulation that meets all of your requirements.

In this product overview, you’ll learn about two types of thermal acoustic insulation – each with part numbers that begin with Z. So whether you say Zee, Zed, or Zulu, you can count on Elasto Proxy’s U.S. and Canadian offices to support the mission every time. (more…)

How to Choose Bulb Trim Seals

Bulb Trim SealsBulb trim seals provide sealing and insulation for doors, hatches, and enclosures. These industrial rubber products have bulb and retainer sections that are made of different materials. The bulb section provides sealing and insulation under compressive force. The trim or retainer presses onto a flange or substrate.  Each section of the seal also has a different durometer or hardness to support proper compression.

This technical article from Elasto Proxy is designed to help you choose the right bulb trim seals for your application. In addition to compound selection and part dimensions, product designers and technical buyers need to consider color, texture, internal supports, and exterior finishes. Your application may also require flame-resistant compounds or rubber that meets specific industry standards. (more…)
