The Elasto Proxy Sample Box: What’s Inside?
Seeing is believing, but there’s nothing like holding a product sample in the palm of your hand. When it comes to rubber, a 90-durometer profile feels like a hockey puck and a 40-durometer component feels like a pencil eraser. Seeing and feeling these rubber products makes them more “real”, and having some samples to choose from provides a fuller sense of what’s available.
For 25 years, Elasto Proxy has been solving sealing and insulation challenges for partners like you. We can’t put a quarter-century’s worth of solutions in one box, but we can show you some samples of our hand-crafted products. So whether you’re looking at our sample box now, or remembering the parts you saw before, we want to make sure you can feel the Elasto Proxy difference.
On the Left
As you look at the sample box, you’ll notice five products on the left that are all shaped like right angles. These door seals differ in terms of materials of construction, splicing method, and features.
ECO4-124-EM is a thin, dual durometer profile that’s been used as a door seal on a truck, and that’s also suitable for mass transit and construction applications. Made of solid and sponge EPDM rubber, this high-quality part is spliced with a 90° corner. ECO4-124-EM also features grooves that allow the seal to be pushed onto a door frame and into place.
APO7-1842 is made of silicone for high-temperature applications such as bakery ovens. Used as a door seal, this part is gray in color with a thin, whitish splice. Elasto Proxy also offers clear splicing for joining bulb gaskets.
EC12-045-EMT1 also features a thin-splice joint, but uses high-bond tape instead. D-shaped with a small rib, this reliable rubber part is used by the mass transit industry to seal engine doors.
EC28-215-EM is bulb seal that’s been film-spliced. This cost-effective bulb trim features a lip that installers bend and push to keep the seal in place. Spliced with a 90° corner, EC28-215-EM is used as a gasket on the bottom of car and truck doors.
APO4-1734 is a rubber profile that’s joined with an injection-molded corner instead of with film splicing. The parts are cut by hand, demonstrating Elasto Proxy’s unique combination of hand craftsmanship and technology. APO4-1734 is made of solid U-channel and is used for sealing latch doors.
In the Middle
With our waterjet cutter, Elasto Proxy can produce parts like you see in the middle of the sample box. Water jet cutting of sheets is fine, fast, and accurate. This versatile cutting method also lets us cut multiple sheets for efficiency – and with minimum waste. Water jet cutting can also produce out-of-the-box sealing and insulation solutions that keep your assembly lines humming.
Some of the samples you see are acoustic materials. Others are parts of insulation panels for heat and sound. By layering different materials into a composite “sandwich”, Elasto Proxy can satisfy even the most demanding application’s appetite.
SH-1000-54-PVTBL is an acoustic foam that’s used inside vehicle cabs to provide a sound barrier. Available in black, tan, and gray, this insulation features a vinyl finish that’s easy to clean. During part installation, assembly line personnel can peel and stick this sound-dampening foam to vehicle interiors.
SH-500-54-MM is installed between steel flooring and rubber matting to provide cushioning, dampen sound, and offer insulation against cold temperatures. Made of a basic rubber blend, this cost-effective closed cell sponge makes surfaces more comfortable to walk on in production environments.
SH-375-54-ZT is another acoustic foam that’s easy to install and clean.Its density is lower than that of SH-500-54-MM, however, so SH-375-54-ZT is softer.
SH-394-9-Z is made of Vulkocell®, apolyurethane elastomer for high-performance applications. Tan in color, this part resembles a piece of bread, but has a much higher density. Applications for SH-394-9-Z include automotive suspensions and floor mats. In cars and trucks, the part absorbs impacts and helps protect the suspension. In military vehicles, Vulkocell® is used to coat floor matting and help absorb the impact of blasts under the vehicle, such as from improvised explosive devices (IEDs).
SH-125-60-F dampens sound in engine bays and can also serve as a firewall. This part resembles recycled fiber, but hardens under application conditions.
SH-500-54-ZTBRA is also used to insulate engine bays. This sandwich-like composite features aluminum facing to reflect the heat, and includes both acoustic foam and a barrier material.
SH-500-58-ZMT is a sandwich-like composite with an aluminum facing and reinforced neoprene skin. The interior layers include a silicone compound for high-temperature resistance.
SH-500-48-MF is a type of acoustic and thermal insulation that features melamine foam. Often, a protective outer layer is added to keep the skin from tearing. The product is lightweight, and this part is recommended for tight sealing.
SH-500-48-ALU is a lightweight, bulletproof aluminum foam. Used in ballistic panels, this material is extremely light because of the presence of air pockets. During production, bubbles cool to create areas with different densities.
On the Right
The rounded receptacles on the right of the sample box contain a wide variety of rubber profiles that can be spliced into gaskets. Look for lock channels, edge trims, D-shapes, E-shapes, T-shapes, O-ring cord, and bulb seals. Both solid and sponge rubber profiles are available.
Let’s take a closer look at some of the parts you’ll find here.
Bulb trim seals come in 35 different shapes and a variety of flange thicknesses. Most are made of EPDM compounds, and all are designed for applications such as when there’s pressure between a door and a moving part.
Edge trim is used to protect personnel from the sharp edges of metal shelving and tabletops. Typically, parts are cut with a saw. Materials of construction include rubber, plastic, and fiberglass.
Rubber profiles are available in different wall thicknesses and include D-Shapes, P-shapes, E-shapes, U-channels, and lip seals. They are cut and glued, typically by applying an acrylic or high bond tape. Some profiles are made of sponge rubber. Others are made of solid materials.
Dual durometer parts feature a base that’s made of solid rubber and a bulb area that’s made of sponge rubber. As their name indicates, these components have areas with different durometers (duro).
Weather stripping is an inexpensive way to seal holes and gaps, typically with doors and windows. Available in a variety of thicknesses, widths, and sizes, weather strip has an exposed skin that reveals the structure of the bulb.
Window channels or lock channels help secure window frames to vehicle bodies and hold window glass in place. They include beaded and unbeaded channels with or without stainless steel beads.
Finally, the profiles at the bottom-right of the sample box come in white, off-white, blue, and even fire engine red. They’re all made of silicone, but Elasto Proxy can source a full range of rubber and plastic materials for your application.
