  • Military Vehicles Need Thermal Acoustic Insulation

    Military Vehicles

    Thermal acoustic insulation is used in the floors, doors, side panels, and engine bays of military vehicles. Many different types of insulating materials are available, but you don’t need to be a material scientist to make the right choice. By choosing an experienced custom-fabricator who provides design assistance and help with material selection, you can strengthen your product designs as well as your supply chain. That’s why the North American defense industry asks Elasto Proxy for thermal acoustic solutions. Continue reading

  • MRAP to MTAP: Rubber Gaskets for Military Vehicles

    Have you ever wondered why the military uses so many acronyms? It's because soldiers, sailors, airmen, and marines need to convey information quickly, accurately, and efficiently. That's why suppliers to the defense industry are also more likely to hear a term such as “MRAP” than the phrase “mine-resistant ambush-protected vehicle”.  For defense contractors who want to win new business, mastering these acronyms can be like learning a new language.

    Like any specialized discipline, gasket design has its own language, too. For example, many rubber gaskets are made of synthetic elastomers with names such as Buna-N and EPDM. Published specifications such as ASTM D2000 use letters and numbers to “call out” the properties of vulcanized rubber in a highly-structured way. Units of measure such as durometer (hardness) are sometimes unfamiliar, so buyers and designers may need assistance in order to translate the language of rubber into project specifications. That's just part of how Elasto Proxy can help. Continue reading

  • Hatch Seals for Military Vehicles

    Hatch Seal Hatch Seal from Elasto Proxy

    In this case study, you’ll learn how Elasto Proxy solved a sealing challenge for a manufacturer of military vehicles. The rubber hatch seals that we supply resist over-compression and demonstrate our defense industry knowledge and technical expertise.

    Hatch seals for military vehicles need to meet multiple requirements. In addition to keeping out wind, water, dirt, and mud, these rubber parts must resist temperatures in environments such as arctic cold and desert heat. Rubber hatch seals need to withstand compression, too. If the vehicle’s hatch causes the seal to over-compress, the rubber part won’t provide proper sealing. Ultimately, this permanent deformation or compression set creates a gap and can cause seal failure. Continue reading

  • Thermal Acoustic Insulation for Military Vehicles

     thermal acoustic insulationIn this case study, you’ll learn how Elasto Proxy applied its expertise in technical design, compound selection, and custom fabrication to replace the thermal acoustic insulation in the engine bays of military vehicles. How can we help you solve your sealing and insulation challenges? Contact us.

    When a manufacturer of military vehicles isn’t satisfied with a product design, more than just the bottom line is at stake. For coalition forces in Iraq and Afghanistan, armored fighting vehicles provide mission-critical force protection. Most military observers focus on features like the steel plating and the guns, but this type of vehicle won’t deploy anywhere without a big diesel engine under the hood.

    In military vehicles such as armored personnel carriers, diesel engines run hot and loud. Without engine bay insulation, this heat and noise could put both the powerplant and military personnel at risk. Thermal acoustic insulation must also meet flame, smoke, and toxicity (FST) standards. In addition, engine bay insulation must withstand vehicle wash-downs and exposure to detergents and other cleaning chemicals. Continue reading

  • Acoustic and Thermal Insulation for Military Vehicles

    Acoustic and Thermal InsulationAcoustic and thermal insulation won’t stop an IED attack, but it’s still mission-critical. Learn about acoustic foams and thermal management materials, and how Elasto Proxy custom-fabricates insulation sandwiches that protect engines and soldiers against noise, heat, and vibrations.

    Clyde Sharpe General Manager at Elasto Proxy

    Military machines like the MRAP are designed to project power while protecting personnel. With their V-shaped hulls and add-on armor, the mine resistant ambush protected (MRAP) vehicle can withstand IEDs, mines, RPG rounds, and small arms fire. Ballistic protection alone won’t keep armored vehicles on patrol, however. The MRAP is powered by a big diesel engine that runs hot and loud. Without engine bay insulation, heat and noise could put both the powerplant and military personnel at risk.

  • Specialty Seals and Custom Insulation for Military Vehicles

    Specialty Seals and Custom Insulation for Military Vehicles Specialty Seals and Custom Insulation for Military Vehicles

    Doug Sharpe President of Elasto Proxy

    Sealing and insulation solutions for military applications must be able to withstand extreme conditions. Depending on the mission, service, and theater of operations, military vehicles may face high or low temperatures, snow or blowing sand, and attacks via land mines, rocket-propelled grenades (RPGs), or improvised explosive devices (IEDs).

    In both Iraq and Afghanistan, armored fighting vehicles played a pivotal role in protecting U.S. and Coalition personnel. Most observers notice a military vehicle’s plating and weapons systems, of course, but rubber also plays an important role. That’s true as well for Coast Guard and Navy frigates, and for Air Force helicopters and air planes.

    Spliced and Molded Window Gaskets

    Elasto Proxy designs and custom-fabricates many different rubber parts for military applications. In the image that accompanies this blog entry, callouts 1 and 2 show examples of spliced and molded window gaskets. With film splicing, our custom fabrication specialists can create rubber gaskets with strong bonds – and without adhesives or secondary trimming.

    Other available splicing solutions include cold bonding, vulcanizing, and C-press injection molding. The C-press process is more expensive than film splicing, but is often the right choice for square gaskets with radius corners. C-press injection molding is also recommended for bulbs with difficult shapes, especially with small-to-medium quantities of the most challenging seal designs.

    Acoustic and Thermal Engine Bay Insulation

    Elasto Proxy also supplies military vehicles with engine bay insulation. In the image above, callouts 3 and 4 are examples of acoustic insulation and thermal insulation. Both types of specialty insulation products can be made of composite materials and then formed into application-specific shapes and thicknesses. Typically, the structure is sandwich-like with multiple layers.

    Acoustic engine bay insulation is usually made of lightweight, sound-dampening materials that allow sound waves to bounce off. Thermal insulation is designed to absorb heat from an engine compartment and deflect heat away from the cab. Silicone, a synthetic resin, is often used because it resists high temperatures and provides acoustic insulation at the same time.

    Windows Channels, Sealing Profiles, and Vibration Mounts

    In addition to window gaskets and engine bay insulation, Elasto Proxy can also supply specialty window channels and custom rubber profiles. In the blog image, the rubber channels shown in callout 5 help can be used to secure window frames and hold window glass in place. These rubber parts also seal gaps and help prevent the ingress of dust, smoke, or water into the vehicle’s interior.

    Elasto Proxy can also custom-fabricate rubber profiles that help keep air, sand, and water out of a vehicle compartments. As callout 5 shows, sponge profiles and solid profiles are available for specialized applications. Finally, as callout 6 indicates, Elasto Proxy can supply vibration mounts for sensitive electronic displays within a vehicle’s interior.

  • How to Select Marine Rubber and Plastic

    Philippe Grenier Production Coordinator at Elasto Proxy

    Rubber and plastic materials for marine applications must be able to withstand water, saltwater, wind, sunlight, temperature extremes, and other environmental conditions. Whether on the high seas or in coastal waters, part failure can sink product designs. For marine buyers and ship builders alike, smooth sailing means choosing the right compounds. Boats are built of many different materials, of course, so rubber and plastic parts must also support larger designs that include metals, composites, and wood.

    Missions and Choices

    Standards for civilian and military shipbuilding can and do differ, and pleasure craft such as yachts and sailboats have different “missions” than frigates and littoral combat ships (LCS). When choosing marine rubbers and marine plastics then, technical buyers may need to account for program and application requirements along with designs and environmental conditions. A compound that’s right for a window seal on a commercial fishing boat may not be recommended for muffling the sound of its diesel engine.

    Despite these differences, many marine vessels use the same general types of rubber and plastic products. In addition to seals and insulation, boat builders need to source rubber trim and plastic bumpers. By working with a supplier who listens to your needs and analyzes your requirements, you can find reliable off-the-shelf or customer-fabricated solutions. With specialty seals and custom insulation, there are many options available. Even an anti-slip pad must be right for marine environments.

    Seals and Insulation

    Ships and boats need high-quality rubber products – including for watertight compartment sealing. Parts such as a latch seal on a ship’s deck, a porthole or window seal that’s close to the waterline, or an access hatch seal for an engine room serve important functions. Depending on the type of marine engine, the door seal on a fuel tank must be able to resist specific petroleum products such as gasoline and diesel fuel. Remember, too, that some two-stroke outboards can use ethanol-blends. Alternative fuels such as biodiesel blends are more common on land, but you may need to account for their use at sea.

    Seals aren’t the only rubber products that can require specialized characteristics. Acoustical and thermal engine bay insulation is also critical. Thermal insulation is designed to absorb heat from a boat or ship’s engine compartment. Often, silicone is used because this synthetic rubber can resist high temperatures while providing acoustic insulation from high-decibel diesel engines. Self-extinguishing firestocks and custom composite insulation are also available. By building sandwich-like composites, custom fabrication specialists can form application-specific shapes and thicknesses

    Trim and Bumpers

    Civilian ships such as yachts, sailboats, tug boats, and fishing vessels also use parts such as rubber trim and plastic bumpers. Naval ships aren’t built for commerce or pleasure, but these durable watercraft still need door, window, and edge finish trim as well as window channels. Sealing and insulation are also mission-critical. As the image that accompanies this blog entry shows, the first LCS in the U.S. Navy, the USS Freedom, has several rows of windows.

    Since our founding 25 years ago, Elasto Proxy has served both the military and maritime industries. Today, light-up rubber bumpers are one of the many solutions that we offer. Equipped with long-lasting, energy-efficient LED lights, each elastomeric bumper is designed to illuminate the location of quays, pontoons, docks and embankments while protecting marine structures against impact by boats or ships.

  • How to Select Military Approved Plastics

    LAV-300x300Doug Sharpe President of Elasto Proxy

    Plastic materials for military applications must be able to withstand demanding conditions. Whether at land, air, or sea (and even space), part failure is not an option. For technical designers and buyers alike, supporting the mission means choosing the right materials.

    Do you need military approved plastics that can withstand the high temperatures of desert battlefields? What about polymers that provide not just water resistance, but resistance to saltwater at low temperatures? How about specialty plastics that can withstand the g-forces encountered during air support sorties?

    Understanding application requirements is important, but compound selection can also mean picking polymers that are approved specifically for military use. So how can you determine what you need? And how can choosing the right partner strengthen your supply chain?

    The Acrylic Glass Example

    Poly(methyl methacrylate) or PMMA is an acrylic glass that’s better known by brand names such as Plexiglas®. Strong and lightweight, this versatile plastic is typically opaque or clear. PMMA weighs only about half as much as regular glass, but has considerably greater impact strength.

    Unlike other plastic materials, Plexiglas can be manufactured to impart light-transmitting, light-focusing, or light-diffusing properties. In addition to offering resistance to ultraviolet (UV) rays, this synthetic polymer can reflect noise, provide heat shielding or heat insulation, and resist scratching.

    Production and repair personnel like working with Plexiglas because it’s tough enough to withstand handling and installation, and can be sawed, routed, and polished to meet application requirements. This PMMA is also desirable because it burns with little smoke and doesn’t form acutely toxic gases.

    Military Specifications and Material Testing

    Do the material properties of PMMAs make them right for every military application? It’s not that simple. For buyers who work with organizations such as the U.S. Department of Defense (DoD), there are published military specifications to consider. (Typically, however, Plexiglas parts are used in aircraft cabin windows, instrument panels, canopies, wingtip camera lenses, and outer laminates.)

    Although these specialty acrylic materials are available in a range of sizes and thicknesses, buyers need to choose plastic products that meet military specifications such as MIL-PRF-5425E. What do military standards like this mean, and why are they so important?

    In the case of MIL-PRF-5425E, this military standard covers material properties such as optical quality, transparency, and heat resistance. In turn, MIL-PRF-5425E incorporates 10 different test methods from the American Society and Testing and Materials (ASTM).

    Typically, supplier websites and data sheets indicate whether a particular plastic meets various ASTM standards. By working with a supply chain partner who can help you with material selection, however, you can simplify the task of sourcing military-approved plastics.

    U.S. DOD standards aren’t the only military specifications in the world, of course. For example, the North Atlantic Treaty Organization (NATO) publishes standardization agreements (STANAG) that establish common requirements for equipment and materials among member nations.

    Underwriters Laboratories (UL) also publishes standards for security applications. UL 752 defines nine protection levels, each for a specific type of ammunition. For example, a Level 1 UL rating is for a 9-mm full metal copper jacket with a lead core. UL’s supplementary shotgun level is for 12-gauge shotguns.

    To select the right military-approved plastics then, you’ll need to understand application requirements, know which standards apply, and also consider program budgets. With regard to costs, consider the case of mine-resistant ambush protected (MRAP) vehicles that U.S. forces use in Afghanistan.

    These military vehicles feature windshields made of an expensive ballistic glass, but it was a specialty laminate that captured headlines several years ago. According to an estimate from the Defense Logistics Agency (DLA), using a tear-away film could help limit windshield replacements and save the Pentagon as much as $75 million annually.
