  • 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

  • Thermal Acoustic Insulation for Reducing Heat and Sound (Part 2)

    thermal acoustic insulation

    This is the second in a two-part series about thermal acoustic insulation from Elasto Proxy, a global supplier of specialty "insulation sandwiches" that reduce both heat and sound.

    Elasto Proxy custom-fabricates thermal acoustic insulation for applications such as mobile equipment and military vehicles. These multi-layer composites meet your application requirements for a complete sealing and insulation solution. They also meet your business requirements for value-added products that are cost-effective, reliable, and easy-to-install on the assembly line or in the field.

    In Part 1 of this series, we examined why diesel-powered vehicles and equipment need insulation with both thermal and acoustical properties. We also examined how heat and sound travel, and some of the insulating techniques that are used.  In Part 2 of this series, we’ll examine two thermal acoustic products (ZTBRA and Z3T) that illustrate Elasto Proxy’s capabilities. Specialized services such as edge sealing for washdown-capable engine bay insulation complement our lamination and water jet cutting skills. Continue reading

    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

  • Thermally-Conductive Silicone Coated Fabrics for Heat Sink Gaskets

    Heat Sink GasketsTechnical buyers and product designers have a choice of materials for heat sink gaskets. Learn about the advantages of thermally-conducive silicone coated fabrics, and how Elasto Proxy creates custom solutions for thermal management challenges.

    Computers, telecommunications equipment, and electronic devices generate significant amounts of heat. Unless this heat is dissipated, component damage and system failure can result. By establishing an effective thermal path between a heat-generating component and a metallic heat sink, thermal interface materials dissipate heat and support product life and performance. Some materials, such as thermally-conductive silicone fabrics, also provide properties that strengthen product designs. 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.

    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.

  • Thermal Insulation and Acoustic Insulation for Military Vehicles and More

    IED attacks, landmines, and mortar fire aren't the only threats to military assets such as mine-resistant ambush protected (MRAP) vehicles. The big diesel engines that power these armored fighting machines generate large amounts of noise and heat. Military specifications limit the amount of noise exposure to occupants, and high heat from vehicle engines can damage components under the hood and make cab temperatures unbearable.

    Acoustic and thermal insulation may not receive the attention of the latest weapons systems, but vehicle designers understand the damage that excessive heat and noise can cause. Along with vibration damping products such as shock absorbers and floor matting, military vehicles like the MRAP may also need impact-resistant insulation that's shrapnel-proof.

    Sound Insulation and Heat Insulation

    Protecting personnel and equipment is a complex task, so defense contractors need partners who understand all of their requirements and can even help design new products. Depending upon the application, technical may need sound insulation, heat insulation, or both.

    Acoustic insulation is usually made of polyethylene or polyester foams that allow sound waves to bounce off. These lightweight, sound-dampening materials may also include a sound-absorbing barrier. Most acoustic insulation has an open cellular structure that permits the passage of air, a good insulator. Closed cell acoustic foams are used mainly in underwater applications rather than land vehicles.

    Thermal insulation is designed to absorb heat from a vehicle's engine compartment and deflect heat away from the cab. Silicone, a durable synthetic resin, is often used because it resists high temperatures and provides acoustic insulation from high-decibel diesel engines. Self-extinguishing firestocks and custom composite insulation are also available.

    Composite Panels and Civilian Applications

    Thermal and acoustic insulation can be made of composite materials and formed into application-specific shapes and thicknesses. For example, thermal-proof panels made of ceramic fiber, polyurethane foam, and microcellular or silicone foam can provide heat shielding as high 1200° C in locomotives. By laminating multiple layers of insulating materials together, suppliers can build sandwich-like panels that are suitable for military or civilian applications.

    Truckers also appreciate the benefits of high-quality insulation. Whether for long-haul trucking, construction site work, or local runs in a garbage truck, sound insulation is important. As with thermal insulation, sound insulating products can be color-matched to the vehicle. In commercial trucks, for example, a vinyl exterior may be applied to enhance the cab's appearance.
