  • Cold Bonding for Rubber Gaskets

    Cold BondingCold bonding for rubber gaskets joins lengths of material without the use of heat. This bonding technique doesn’t require low-temperature conditions, but is called “cold” because no heat is applied to the gasket. By contrast, hot splicing requires either a conventional heat source or infrared (IR) light. Vulcanization and molded corners for rubber gaskets also involve heating gasket materials.

    With cold bonding, an adhesive is applied to the ends of the lengths that will be joined together. Different types of bonding systems are available, including compounds that vary in terms of viscosity, chemistry, and material properties. Cold bonding for rubber gaskets can save time and eliminate tooling costs, but engineers need a complete understanding of this joining method before choosing glued gaskets. Continue reading

  • How to Install Rubber Gaskets

    Install Rubber GasketsDo you know how to install rubber gaskets for optimal sealing and insulation? If rubber seals are installed improperly, small leaks can admit air, water, dust, light, and sound. That’s a big problem for assembly and maintenance personnel who work in industries like mobile equipment, defense, aerospace, stainless steel and food equipment, infrastructure, and medical and health.

    Engineers and sourcing managers can help by specifying the right profile materials, but gasket installation is about more than compound selection. Gaskets can attach with mechanical fasteners, but bolts and screws require tools. Plus, mechanical fasteners can loosen from vibrations. Adhesives are great for gasket installation, but spray-on systems are messy and can raise environmental health and safety concerns.

    In this article from Elasto Proxy, the first in a series of “how to” blog entries, we explain how to install rubber gaskets for sealing and installation. In addition to adhesive selection, you’ll learn about key profile measurements. Importantly, Elasto Proxy shares requirements and best practices, too. If you want to learn how to install rubber gaskets, this article is for you. Continue reading

  • Rubber Door Seals for Walk-In Bathtubs

    Walk-in BathtubsWalk-in bathtubs allow people with limited mobility to bathe themselves safely and independently. Typically, they’re used in hospitals, healthcare settings, retirement communities, and assisted living facilities. Unlike a traditional bathtub, a walk-in bathtub has a door on the front or side of the unit. This allows users to enter and exit the tub without having to lift their legs over the side. This reduces the chance of slip-and-fall injuries, and also supports wheelchair accessibility.

    Walk-in bathtubs feature various door designs and come with various capabilities. Hydrotherapy options include whirlpools and adjustable bubble jets. Units with adjustable shower heads, integral handrails, LED lighting, and inside-the-tub seating are also available. Many walk-in bathtubs now include fast-draining capabilities so that users don’t need to remain in the unit for long periods of time while the bathtub empties. Product features vary, but all walk-in bathtubs need reliable rubber door seals. Continue reading

  • Four Reasons to Meet Elasto Proxy at IDEX 2017

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

  • Gensets: Door Seals, Acoustic Insulation, and Rubber Bumpers

    GensetsGensets 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

  • Silicone Gaskets with High Flex-Fatigue Resistance

    Flex Fatigue ResistanceElasto 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

  • Graphite Gaskets for Temperature, Pressure, and Corrosion Resistance

    Graphite GasketsThis graphite gaskets article is the second in a series about textile-based gaskets for industrial fluid sealing.

    Graphite gaskets combine strong thermal resistivity with resistance to thermal shock, a type of damage that occurs when components are subjected to rapid changes in temperature. Typically, these industrial gaskets are fabricated from expanded sheets and foil-core materials. Graphite gaskets from Elasto Proxy are fabricated through water jet cutting and support the use of pressure-sensitive adhesives (PSAs) for ease-of-application on your assembly line or in the field.

    As a reinforcing textile, graphite also provides numerous advantages. Unlike other types of gasket materials, graphite’s mechanical properties increase with temperature. In multi-layer components, graphite can be sandwiched together with other gasketing materials (such as foils) to create custom sealing and insulation solutions. Graphite is also flexible and can be produced without fillers or binders that can limit sealing performance in demanding applications. Continue reading

  • Non-Asbestos Gaskets: Aramid Fibers and Rubber Binders

    Non-Asbestos GasketsThis non-asbestos gaskets article is the first in series of about textile-based gaskets for industrial fluid sealing.

    Non-asbestos gaskets provide durable, flexible sealing and insulation in high-temperature environments that also require resistance to air, water, steam, oils, acids, or chemicals. These industrial gaskets are made of compressed sheet materials that consist of fibers such as aramid and an elastomeric binder. Aramid fibers are exceptionally strong and heat resistant. The rubber binder that’s used enhances the seal’s mechanical properties and promotes torque retention.

    In this technical article from Elasto Proxy, the first in a series about textile-based gaskets for industrial fluid sealing, we’ll examine the advantages of non-asbestos gaskets made of aramid fibers. We’ll also compare four different binder materials that enhance the performance of aramid as a gasketing material. As an experienced provider of sealing and insulation solutions, Elasto Proxy can recommend the right gasket materials, provide seal design assistance, and custom-fabricate your gaskets with precision.

  • Vibration Damping Materials and Acoustic Insulation

    Vibration DampingElasto Proxy explains what you need to know about choosing vibration damping materials. This article is the final installment in our multi-part series about acoustic insulation.

    Vibration damping materials are acoustically optimized to reduce resonant vibrations that can cause unwanted noise or sound. Applications include machine enclosures, hospital equipment, electronic devices, and engine bays. If vibrations aren’t dampened, high cycle fatigue can cause components to fail. Excessive noise, vibration, and harshness (NVR) can also suggest poor quality in manufactured products. With electronic devices, vibrations can weaken soldered connections and even result in the loss of data. Continue reading
