Engine compartment insulation keeps heat and noise in the engine bay from reaching a vehicle’s interior. Thermal insulation protects drivers, operators, and passengers from high temperatures that can also damage on-board electronics such as GPS tracking systems. Acoustic insulation dampens damaging sound-induced vibrations and protects personnel from decibel levels that can harm human hearing.
With forestry equipment, military land systems, and other types of mobile specialty vehicles, the cab where the operator sits is usually next to the engine compartment. If the cab is directly above the engine bay, installing thermal-acoustic insulation under the cabin floor is a smart choice. Cabin insulation supports additional noise reduction. Inside the engine compartment, insulation is attached to the firewall.
For mobile equipment manufacturers, choosing the right engine bay insulation is an important design consideration. Product designers and engineers need to understand their options, but it’s also important to understand how thermal-acoustic insulation is made. Engine compartment insulation that’s custom-fabricated doesn’t just reduce heat and sound. It helps you to control costs and improve quality.

How 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. Continue reading How Silicone Rubber Is Used for Sealing and Insulation
Unmanned ground vehicles (UGVs) need rubber UGV gaskets that can help protect sensitive electronics from high heat. UGVs also need weather-resistant door and hatch seals, and custom gaskets for cameras and LED lights that can handle extreme temperatures while keeping out water and dust. Manufacturers of UGV electronics, vehicle bodies, and imaging systems must meet different requirements, but custom fabrication can solve sealing and insulation challenges across the UGV supply chain.
Elasto Proxy, a global supplier of specialty rubber products, custom-fabricates the rubber gaskets that unmanned systems need. In this article, the second in a series about unmanned vehicles, Elasto Proxy examines three types of UGV gaskets: thermally-conductive insulation, environmental seals, and rubber gaskets for cameras and LED lights. Part 1 of this series covered UAV gaskets. Future articles will examine seals and insulation for USVs, UUVs, commercial drones, and unmanned system accessories.

Thermal-acoustic insulation for military land systems absorbs heat and sound. These composite structures are used in engine compartments, doors, floors, side panels, and hatch covers. Elasto Proxy custom-fabricates thermal-acoustic insulation from foams, films, facings, and other specialized materials that meet your requirements. Our capabilities include water jet cutting for precise cuts, lamination for the reliable joining of different materials, and taping for thermal-acoustic insulation that’s easy-to-install.
For designers of military vehicles, it’s important to specify thermal-acoustic insulation that supports the mission. The big diesel engines that power military land systems run hot and loud. Heat and noise from the engine bay don’t just make the crew compartment uncomfortable. The air conditioning needs to run constantly, soldiers can’t hear each other over engine sounds, and the vehicle’s thermal profile is more susceptible to infrared detection. High heat can damage vehicle electronics, too. Continue reading Thermal-Acoustic Insulation for Military Land Systems
Engine bay insulation for military vehicles keeps noise and heat in the engine bay from reaching the passenger compartment. The diesel engines that power military land systems run loud and hot, raising concerns about solider health and safety. Warfighters need to be able to hear each other above engine sounds, and a vehicle where the air conditioning runs full-blast is less fuel-efficient. Hotter vehicles also have stronger heat signatures, making them more susceptible to thermal detection by hostile forces.
Thermal-acoustic insulation is important, but manufacturers of military vehicles also need to protect on-board electronics and instruments from sound-induced vibrations. Otherwise, these noise disturbances can shorten equipment life through component failure. Resistance to flash and fire supports the mission, too. Engine bay insulation must also resist oil and automotive chemicals, withstand washdowns with water and detergents, and support cost-effective fabrication. Continue reading Engine Bay Insulation for Military Vehicles
EMI shielding gaskets for military electronics are used in everything from touchscreens to targeting systems. To prevent electromagnetic interference (EMI) from disrupting electronic equipment, Elasto Proxy custom-fabricates EMI shielding gaskets from particle-filled silicones. These specialized materials combine the materials properties of silicone rubber with the electrical properties of metal. Elasto Proxy uses waterjet cutting to convert shielding silicones, and bonds cut lengths with conductive adhesives.
EMI gaskets from Elasto Proxy meet the requirements of MIL-DTL-83528, a U.S. Defense Logistics Agency (DLA) specification for electrically-conductive elastomeric shielding gaskets. MIL-DTL-83528 establishes minimum shielding effectiveness levels for various material types over a frequency range of 20 MHz to 10 GHz. MIL-DTL-83528 also specifies hardness or durometer (Shore A) measurements for shielding silicones that are categorized as low, medium, or high durometer. Continue reading EMI Shielding Gaskets for Military Electronics
IDEX is the world’s most strategically important tri-service defense exhibition. For OEMs, military buyers, and prime contractors, this global event is the place to find technologies for land, air, and sea. The International Defense Exhibition and Conference (IDEX) is also where defense subcontractors present key component-level solutions for military programs and projects. That’s why Elasto Proxy, a leading custom-fabricator of specialty seals and insulation, will highlight four unique solutions at IDEX 2017. Continue reading Four Reasons to Meet Elasto Proxy at IDEX 2017
Gensets or generating sets are designed to supply off-grid electricity. They usually consist of a diesel or gasoline-powered engine and an electrical generator (such as an alternator) that converts mechanical power into electricity. Some gensets, such as the ones that provide emergency backup power at hospitals and water treatment plants, are large and stationary. Others gensets are portable because they’re wheeled, or are mounted on wheeled trailers that are pulled by trucks or other motorized vehicles. Continue reading Gensets: Door Seals, Acoustic Insulation, and Rubber Bumpers
Elasto Proxy custom-fabricates silicone gaskets with high flex-fatigue resistance. These specialty gaskets are made of materials that meet the A-A-59588 3B specification for 50, 60, and 70-durometer silicones.
Silicone gaskets have many desirable properties. They’re chemically inert, resistant to ozone and ultraviolet light, offer thermal stability over a wide temperature range, and can repel water and form watertight seals. Silicone rubber is used in a variety of sealing and insulation applications, but some silicones have inadequate flex-fatigue resistance – a measure of a material’s ability to withstand repeated flexing or bending without cracking.
In some industries, however, flex-fatigue resistance is required. For example, aerospace engineers need silicones with high flex-fatigue resistance for door seals, window seals, and vibration-isolating mounts used with alternators, compressors, and assembly bolts. Members of the mobile equipment industry need crack-resistant silicones for engine mounts and exhaust hangers. Designers of aerospace and defense electronics need silicones that can flex without cracking in high-performance keypads. Continue reading Silicone Gaskets with High Flex-Fatigue Resistance
